Abstract:
... Vine weevil, Otiorhynchus sulcatus F. (Coleoptera: Curculionidae), is an economically important insect pest of horticultural crops. To identify an effective and reliable monitoring system for adult vine weevil, this study investigated the influence of colour, height and entrance position on the efficacy of a model monitoring tool using modified paper cups as refuges. Vine weevil preferences were d ...

Abstract:
... To develop a new pest control device for greenhouses, we verified the effect of the noncontact force generated by ultrasonic transducers on two small insect pests: the sweet potato whitefly Bemisia tabaci Gennadius and the cotton aphid Aphis gossypii Glover. First, we examined their dispersion behavior in response to the device, and the dispersion rate of whiteflies from leaves was approximately 6 ...

Abstract:
... BACKGROUND: Conidia from Metarhizium are part of the commercial formulations used worldwide for insect pest control. Among the alternatives proposed to improve conidia production, the use of packed column bioreactors allows controlled processes with higher levels of production and productivity than those obtained with the traditional process in plastic bags. However, problems associated with overh ...

Abstract:
... Coffee berry borer (CBB) (Hypothenemus hampei; Coleoptera: Curculionidae: Scolytinae) is a major insect pest affecting coffee cultivation that causes large economic losses worldwide. Characteristics related to its life cycle makes it very difficult to control. Usually, CBB control measures are carried out at plot scale, with almost no actions taken at wider landscape scales. It is unclear how plot ...

Abstract:
... Greenbug (Schizaphis graminum Rondani) is a destructive insect pest that not only damages plants, but also serves as a vector for many viruses. Host plant resistance is the preferred strategy for managing greenbug. Two greenbug resistance genes, Rsg1 and Rsg2, have been reported in barley. To breed cultivars with effective resistance against various greenbug biotypes, additional resistance genes a ...

Abstract:
... Inundated release of parasitoids is an environmentally friendly pest insect control method. Deep understanding influence of different temperatures on development of parasitoids is very helpful for improving biological control effectiveness. Thus, the life history parameters of Anisopteromalus calandrae (Howard) (Hymenoptera: Pteromalidae) reared on mature larvae (about 30 days old) of Lasioderma s ...
... The advent of genetically modified crops expressing insecticidal proteins of the bacterium Bacillus thuringiensis (Bt) revolutionized the management of insect pest species. Nonetheless, such disruption does not come free from controversies and concerns. The quick spread of Bt resistance in targeted pest species is an example, and the impact in non‐targeted arthropod species is another. The former ...

Abstract:
... Insect pests of cocoa constitute a major production constraint in Ghana and they are the cause of significant crop losses and reduced income for smallholder farmers annually. Pest control is mainly achieved through the application of insecticides with different modes of actions. These insecticides are either synthetic for conventional cocoa production systems or of natural botanical sources for or ...
... We present a de novo mitogenome assembly obtained from specimens sampled in the so-called summer population (SP) of Thaumetopoea pityocampa (Denis and Schiffermüller, 1775) in Portugal. Contrary to the typical larval development occurring in winter in this species, the larvae of this unique population develop during summer. The sequencing data used were obtained from genomic libraries originally g ...
... Accurately counting the number of insect pests from digital images captured on yellow sticky traps remains a challenge in the field of insect pest monitoring. In this study, we develop a new approach to counting the number of insect pests using a saliency map and improved non-maximum suppression. Specifically, as the background of a yellow sticky trap is simple and the insect pest object is small, ...

... Fall armyworm (FAW) Spodoptera frugiperda is considered the main defoliating insect pest of maize in many countries. Silicon (Si) applied to plants has been shown to increase the resistance to insects, especially in grasses such as maize. This study characterized the effects of Si fertilization regarding priming, induced resistance, and tolerance to FAW in a landrace variety and hybrid of maize. S ...
... Great tits are insectivorous birds that feed mainly on caterpillars during the breeding season. Their high pest control potential in apple orchards has been documented. Nestbox provisioning is an increasingly suggested tool for ecological pest control, but the underlying assumption that birds forage in intensively managed orchards has never been formally tested. We conducted a fine-scale study of ...
... The wide spread cultivation of transgenic Bt-cotton in India has altered the pest profile from bollworms to sap-sucking insect-pests especially whitefly [Bemisia tabaci (Gennadius)]. A whitefly epidemic in 2015 destroyed cotton crop on nearly 1.5 million hectares in North Indian cotton growing states. Management of whitefly is not easy due to its wider host adaptability, potential for insecticide ...
... Human-modified landscapes are often composed of small and isolated natural habitat fragments immersed in agricultural and urban matrices. Within them, ecosystem services provided by wildlife, such as pest insect suppression, may decrease or even be lost leading to a substantial increase in agricultural production costs. Pest insect suppression by bats has been identified as an essential ecosystem ...
... Weevil (Sitophilus zeamais Motsch.) is a vital arthropod pest of maize (Zea mays L.) grains and flours in traditional storage systems. The pest bore holes into stored grains reducing their nutrient contents germination potentials and contaminating produce with frass. Its control using synthetic insecticides such as permethrin is being downplayed due to eco-mammalian toxicity from pesticide residue ...

Abstract:
... Flonicamid (N-cyanomethyl-4-trifluoromethylnicotinamide) is a novel systemic insecticide that shows high insecticidal toxicity against sap-sucking pests. However, little is known about the sublethal effects of flonicamid on melon aphid, Aphis gossypii Glover, a serious insect pest of many vegetables. Herein, the toxicity of flonicamid to A. gossypii was determined using the leaf-dipping method, an ...

Abstract:
... The beet army worm, Spodoptera exigua, is a widely distributed polyphagous pest of economically important crops worldwide. The management of this pest insect continues to face many challenges. Despite synthetic chemicals posing a serious threat to the environment, these remain the conventional approach for controlling S. exigua in the field. An over-reliance on chemical control has not only led to ...
