... Complementary sex determination (CSD) is a widespread sex determination mechanism in haplodiploid Hymenoptera. Under CSD, sex is determined by the allelic state of one or multiple CSD loci. Heterozygosity at one or more loci leads to female development, whereas hemizygosity of haploid eggs and homozygosity of diploid eggs results in male development. Sexual (arrhenotokous) reproduction normally yi ...
... The majority of adult parasitoid wasps are unable to synthesize lipids and therefore face a trade‐off between the investment of lipids in eggs or in the maintenance of soma. It has been shown that resource allocation should depend on body size in parasitoids. Given that smaller females have shorter expected life times, they should concentrate their reproductive effort into early life. To test this ...
... A total of 817 samples (1,094.36 kg) of potential fruit fly (Diptera:Tephritidae) hosts were collected from 70 plant species across 29 families in the state of Amapá, Brazil. Twenty-three of these plant species were infested with tephritid larvae. Twelve species of Anastrepha were recovered in different proportions: Anastrepha striata (82.65%), Anastrepha coronilli (6.63%), Anastrepha obliqua (5.4 ...
... Infection with Wolbachia is known to induce diploidization of haploid eggs and enables the production of females from unfertilized eggs. Although there have been several attempts to achieve the artificial horizontal transfer of thelytoky-inducing Wolbachia in parasitoid wasps, the artificial induction of thelytoky has generally been unsuccessful. In this study, we used two strains of Asobara japon ...
... Few examples exist where parasites manipulate host behaviour not to increase their transmission rate, but their own survival. Here we investigate fitness effects of parasitism by Asobara species in relation to the pupation behaviour of the host, Drosophila melanogaster. We found that Asobara citri parasitized larvae pupate higher in rearing jars compared to unparasitized controls, while A. tabida ...
... Asobara japonica (Braconidae) is an endophagous parasitoid developing in Drosophila larvae. The present study shows that A. japonica was never encapsulated in Drosophila melanogaster, and that it caused an overall inhibition of the host encapsulation reaction since injected foreign bodies were never encapsulated in parasitized hosts. Both the number of circulating hemocytes and the phenoloxidase a ...

Abstract:
... In just a few years, the Asian fly Drosophila suzukii has invaded several continents and has become a very serious pest of many fruit crops worldwide. Current control methods rely on chemical insecticides or expensive and labour‐intensive cultural practices. Classical biological control through the introduction of Asian parasitoids that have co‐evolved with the pest may provide a sustainable solut ...
... Fruit flies (Diptera: Tephritidae) are major constraints on the production and marketing of fruits in African tropical and subtropical countries. In a perspective to manage these fly pests, an inventory of parasitoids associated with fruit flies was carried out from 2009 to 2011 in southern Togo through various fruit incubations. Nine species of native hymenopteran parasitoids associated with eigh ...
... Wolbachia is a maternally inherited bacterium that manipulates the reproduction of its host. Recent studies have shown that male-killing strains can induce cytoplasmic incompatibility (CI) when introgressed into a resistant host. Phylogenetic studies suggest that transitions between CI and other Wolbachia phenotypes have also occurred frequently, raising the possibility that latent CI may be wides ...

Abstract:
... The Drosophila parasitoid system is an excellent model for the study of biological and ecological interactions. In Japan, extensive studies have been carried out on Drosophila parasitoids since the early 2000s. Here we provide up‐to‐date information on their diversity, distributions, host use and reproductive mode. Until now, 45 wasp species have been recorded. In addition, four genetically distin ...
... Populations of the leafminer, Scaptomyza flava , were monitored fortnightly in turnip plantings at Pukekohe, south Auckland, for more than 2 years. The fly, and its main parasitoid, Asobara sp. (nr. persimilis) (Hymenoptera: Braconidae), were present throughout the year, with populations peaking in midsummer on spring plantings. A replicated field trial, comparing four planting dates, suggests tha ...
... Ovipositing Asobara japonica females inject venom (containing paralysis-inducing factors) immediately after the insertion of their ovipositors into Drosophila larvae, and lay eggs a little later. Interruption of their oviposition behaviour before egg laying causes high larval mortality in host Drosophila species, whereas normal oviposition does not. This suggests that venom of this parasitoid is t ...

Abstract:
... Drosophila suzukii is native to East Asia and an invasive pest of fruit crops widely established in the Americas and Europe. The lack of effective indigenous parasitoids of D. suzukii in the invaded regions prompted surveys for co-evolved parasitoids in Yunnan Province, China, from 2013 to 2016. From banana-baited traps (2013–2015), 458 parasitoids of drosophilids were reared, comprised of Braconi ...

Abstract:
... The invasive spotted wing drosophila, Drosophila suzukii Matsumura (Dipt.: Drosophilidae), a native of East Asia, has widely established in North America and Europe, where it is a serious pest of small and stone fruit crops. The lack of effective indigenous parasitoids of D. suzukii in the recently colonized regions prompted the first foreign exploration for co-evolved parasitoids in South Korea d ...
... Phenacoccus solenopsis (Hemiptera: Pseudococcidae) is the most important scale pest of cotton (Gossypium hirsutum) around the world and has emerged as an important pest on a wide range of host plants in many countries. This scale insect was first detected in Morocco in 2020 during sampling in a cactus crop in the Benni Mellal region (32° 20′ N, 6° 21′ W) and has also been found on many other non‐c ...

Abstract:
... Drosophila suzukii has become a key invasive pest of soft- and thin-skinned fruit crops in its invaded regions in Europe and Americas, where locally-occurring natural enemies are generally not effective for the suppression of this pest or are largely absent, such as larval-attacking parasitoids. As a part of systematic evaluations of candidate agents for classical biological control of this invasi ...
... Accumulating evidence suggests that genotype of host insects influences the development of koinobiont endoparasitoids. Although there are many potential genetic variations that lead to the internal body environmental variations of host insects, association between the host genotype and the parasitoid development has not been examined in a genome-wide manner. In the present study, we used highly in ...
... 1. Generalist koinobiont parasitoids often exhibit high flexibility in their development; their larvae shorten or prolong the developmental period depending on the host quality at parasitisation. However, flexibility of the growth rate of parasitoid larvae has rarely been investigated so far. 2. This study investigated how the koinobiont parasitoid wasps Asobara japonica and Leptopilina ryukyuensi ...
... Insect parasitoids can attack phylogenetically related hosts that share similar physiological properties and defense mechanisms and, more importantly, overlapping ecological niches. Here, host preferences of three parasitoids, Asobara japonica (Hymenoptera: Braconidae), Ganaspis brasiliensis and Leptopilina japonica (Hymenoptera: Figitidae), were examined on two closely related hosts, Drosophila s ...
... We studied the host range of Asobara japonica, a larval-pupal parasitoid of drosophilid flies. Habitat selection was found to be an important determinant of host range in this parasitoid; it attacked drosophilid larvae breeding on banana and mushrooms, but seldom attacked those breeding on decayed leaves. This parasitoid was able to use diverse drosophilid taxa as hosts. Attack by A. japonica some ...
... The Asian spotted wing drosophila, Drosophila suzukii, has recently become a serious pest of soft fruits in Europe. Classical biological control through the introduction of larval parasitoids from its native range in Asia is presently being considered. However, host specificity of potential biological control agents has to be determined to avoid releasing species that may have unintended non-targe ...
... The interactions between Drosophila melanogaster and the parasitoid wasps that infect Drosophila species provide an important model for understanding host–parasite relationships. Following parasitoid infection, D. melanogaster larvae mount a response in which immune cells (hemocytes) form a capsule around the wasp egg, which then melanizes, leading to death of the parasitoid. Previous studies have ...
... The relationship between host and parasitoid has been examined in terms of either the effects of infestation on host growth and development, or the growth and development of parasitoid larvae in response to the physiological and nutritional status of their hosts. Although a wide range of host–parasitoid interactions has been studied, detailed developmental profiles of parasitoid larvae and environ ...

... Insect parasitoids are often manipulated to improve biological control programs for various arthropod pests. Volatile compounds can be a relevant cue used by most parasitoid hymenoptera for host or host microhabitat location. Here, we studied olfactory responses of the braconid Asobara japonica Belokobylskij, an Asiatic endoparasitoid of the invasive pest Drosophila suzukii (Matsumura), toward its ...
... Developmental time and body size correlate with lifespan in a wide range of taxa, although not in insect parasitoids. When the rate of development is independent of adult metabolic rate, adult lifespan is free to adapt to the adult environment. We suggest that interspecific variation in intrinsic adult metabolic rates, differences in allocation of lipids to longevity, and reproduction and differen ...
... The association among Anastrepha species, braconid parasitoids and host fruits in southern Bahia is recorded. Doryctobracon areolatus (Szépligeti) was associated with A. serpentina (Wied.) in Pouteria caimito, A. bahiensis Lima in Helicostylis tomentosa, A. sororcula Zucchi in Eugenia uniflora, and A. obliqua (Macquart) in Spondias purpurea. Anatrepha obliqua was unique in fruits of Averrhoa cara ...

Abstract:
... Ecological communities are composed of many species, forming complex networks of interactions. Current environmental changes are altering the structure and species composition of ecological networks, which could modify interactions, either directly or indirectly. To predict changes in the functioning of communities, we need to understand whether species interactions are primarily driven by network ...
... The objective of this work was register the occurrence of Anastrepha species and parasitoids associated to fruits of Spondias mombin in three municipalities of the state of Amapá, Brazil. We collected fruits of S. mombin in the municipalities of Oiapoque, Porto Grande and Mazagão (10 samples per municipality, each one consisting of about 1 kg of fruit) in February and March 2014. We obtained 2,715 ...
... The olfactory responses of the native parasitoids Doryctobracon areolatus (Szépligeti) and Asobara anastrephae (Muesebeck) and of the exotic parasitoid Diachasmimorpha longicaudata (Ashmead) to guava (Psidium guajava L.) infested or not with fruit fly larvae were evaluated. D. areolatus and D. longicaudata females responded to the odors of uninfested rotting guavas, although D. areolatus was also ...
... Predicting the outcome of interspecific interactions is important in designing biological control programs that involve multiple species introductions. Three solitary larval endoparasitoids, Asobara japonica Belokobylskij (Hymenoptera: Braconidae), Ganaspis brasiliensis Ihering and Leptopilina japonica Novković & Kimura (both Hymenoptera: Figitidae) from Asia are potential agents for classical bio ...
... Asobara japonica (Hymenoptera: Braconidae), Ganaspis brasiliensis and Leptopilina japonica (Hymenoptera: Figitidae) are Asian larval parasitoids of spotted wing drosophila, Drosophila suzukii (Diptera: Drosophilidae). This study evaluated these parasitoids’ capacity to attack and develop from 24 non-target drosophilid species. Results showed that all three parasitoids were able to parasitize host ...
... Unlike other Drosophila species, the invasive Drosophila suzukii Matsumura (Diptera: Drosophilidae) shows a remarkable pest status. Among the physiological traits that may explain the high level of resistance to parasitoids of Drosophila larvae, the haemocyte load is shown repeatedly to play an important role. To determine whether haemocyte load can explain immunity resistance of D. suzukii to par ...
... The Palearctic species of Braconidae with brachypterous, micropterous, or apterous modification are discussed. The following new species are described: Chremylus planispinus Belokobylskij (France, Algeria), Chremylus algecirasus Belokobylskij (Spain), Pambolus erogolus Belokobylskij (Mongolia), Pambolus ovchinnikovi Belokobylskij (Kyr- gyzstan), Hormius stauropolicus Belokobylskij (Russia (North C ...

... The Drosophila parasitoid Asobara japonica Belokobylskij (Hymenoptera: Braconidae) has highly toxic venom that kills host larvae if its injection is not followed by an injection of lateral oviduct components along with egg‐laying. In the present study, the venoms of seven other Drosophila parasitoids (Asobara rossica, Asobara rufescens, Asobara pleuralis, Leptopilina heterotoma, Leptopilina japoni ...
... The tolerance and utilization of ethanol, acetic acid and acetaldehyde vapour was investigated in Asobara persimilis (Hymenoptera: Braconidae), a parasitoid of Drosophila. No significant utilization of ethanol or acetaldehyde occurred at low concentrations (<1.5% and 0.1% respectively), however both female and male longevity was increased at concentrations of 1.0 and 1.5% acetic acid. All substanc ...

Abstract:
... Wolbachia is a maternally inherited bacterium that is widely distributed among arthropods, in which it manipulates the reproduction of its hosts. Although generally facultative for its hosts, Wolbachia has recently become obligatory in Asobara tabida (Hymenoptera: Braconidae) in which it is required for the completion of oogenesis. Here, we describe a new Wolbachia strain (wAjap) that is associate ...
... Distributions and oviposition sites of Drosophila suzukii (Matsumura) and its parasitoids on wild cherry tree were studied in early summer in a suburb of Tokyo, central Japan. Adults of D. suzukii occurred in the foliage layer as well as in the undergrowth layer. The number of D. suzukii that emerged did not significantly differ between wild cherry fruit collected from the foliage layer and those ...
