Abstract:
... Traps are routinely used in insect ecology, conservation, and pest control, but the understanding of trap counts remains limited. A well developed theory only exists for non-baited traps (e.g. pitfall traps) and the simplest animal movement modes, such as Brownian motion, but not for more complex or realistic situations. In particular, important questions as to how the trap counts may differ in ca ...

Abstract:
... Humans prey on animals with often dramatic effects on abundances, but also alterations to the phenotypical composition of prey populations. Instances of lethal management provide an opportunity to explore proximate mechanisms of phenotypical change. While there is evidence from exploitative predation (e.g. fisheries) that prey can change via evolutionary mechanisms, we present one of the first stu ...

Abstract:
... This review describes an innovative and efficient modification of a type of Malaise trap meme overlooked in a recent review of such insect traps. It further identifies the large variety of dipteran parasites of vertebrates caught in the traps when CO₂ was added as an attractant that otherwise rarely were caught in unbaited traps. Baited trap catches of parasitic flies mimicked those caught attacki ...

Abstract:
... We describe the identification, synthesis, and field-testing of aggregation-sex pheromones, or likely pheromone candidates, of seven species of South American cerambycid beetles in the subfamily Cerambycinae, of the tribes Eburiini and Neoibidionini. Analyses of extracts of volatiles released by adult males revealed that Eburodacrys dubitata White produce 11-methyltridecanal, whereas the males of ...

Abstract:
... During the last century, the range of the American burying beetle (Nicrophorus americanus Olivier) has been reduced by >90%. Only isolated, extant populations of this federally threatened species now exist, primarily in the Great Plains. Although the primary reason for this decline remains unclear, anthropogenic changes to habitat and vertebrate food sources used for reproduction have played a sig ...

Abstract:
... Forensic Entomology can be defined as an area of Biological Sciences that uses the knowledge about insects and other Arthropods in criminal investigations, since decomposing corpses are sources of resources for arthropods, including insects belonging to the Coleoptera order. The objective of this work was to carry out a rapid assessment inventory of beetles of forensic importance in an urban fragm ...
baittraps, etc ; Portunus; cost effectiveness; fisheries; seafoods; spawning; Indonesia; Sri Lanka; Show all 8 Subjects
Abstract:
... Quantitative assessment and management of small-scale fisheries is a persistent problem for fisheries. Crustaceans are particularly challenging for conventional techniques because their lack of permanent hard body parts makes ageing difficult. While a growing body of literature is aimed at developing alternative approaches to small-scale fisheries assessment there are concerns about the indiscrimi ...

Abstract:
... Detection of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), relies heavily on traps baited with the male attractant trimedlure. This lure is dispensed from solid polymeric plugs (2 g a.i.) that are changed out every 6 wk, because beyond this interval their attractiveness drops significantly below that of fresh lure. Existing data suggest that plugs loa ...

Abstract:
... We found Multilure traps baited with Strepha Trap® to be a useful method for sampling arboreal ants. A total of 7 ant species (Hymenoptera: Formicidae) were recorded from 8 Multilure traps associated with tree canopies in a Neotropical transition region in northeastern Mexico. The genus Azteca and the species A. schimperi Emery are reported for the first time in the state of Tamaulipas, Mexico. Th ...
... The role of leaf cuticular wax of cabbage, Brassica oleracea L., rapeseed, B. campestris L., and Indian mustard, B. juncea L. in host preference by two generalists, Spilarctia obliqua Walker and Pieris brassicae L., and a specialist, Plutella xylostella L. was investigated under laboratory conditions. A total of 25 n-alkanes from n-C₁₄ to n-C₃₆ and 15 free fatty acids (FFAs) from C₁₂:₀ to C₂₂:₀ we ...

Abstract:
... The UK coastal trap fisheries target two key species, European lobster Homarus gammarus (L.) and brown crab Cancer pagurus L. Their stock status is assessed periodically using size‐based, yield‐per‐recruit analysis. Fishery trends are described using landings and, where available, effort data to estimate catch per unit of effort (CPUE), nominally proportional to abundance. Despite being caught tog ...

Abstract:
... BACKGROUND: Vector surveillance is essential in determining the geographical distribution of mosquito vectors and understanding the dynamics of malaria transmission. With the elimination of human malaria cases, knowlesi malaria cases in humans are increasing in Malaysia. This necessitates intensive vector studies using safer trapping methods which are both field efficient and able to attract the l ...

Abstract:
... The addition of synthetic (E)-anethol to the known attractant phenylacetaldehyde synergized attraction of the cotton bollworm Helicoverpa armigera, the blend invariably catching 4 to 6 times more than phenylacetaldehyde on its own. Highest catches were recorded by the 1:1-3:1 blends. The addition of salicyl aldehyde, ±linalool, (R)-(+)-limonene, 2-methoxybenzyl alcohol and 4-methoxybenzyl alcohol ...

Abstract:
... Species of the Papilionidae, Pieridae, and Nymphalidae families of Lepidoptera were inventoried, diversity of habitats of the core area of the ecological reserve “El Tisey-La Estanzuela” (natural protected area) of Nicaragua was analyzed, and butterfly food guilds and efficiency of collection methods were determined. The study was at 11 sites: Bosque Pino Santa Rosa, Bosque Mixto Napoleón, Bosque ...

Abstract:
... Animal personality, behavioural differences among individuals which are consistent through time and contexts, is generally described by one or more traits. Different methods are used to measure these traits, such as behavioural observations and trapping indices. Comparing several methods allows to validate different tests and to better identify which aspect of an animal's personality is being meas ...

Abstract:
... Timely insecticidal application for Stathmopoda masinissa Meyrick (Lepidoptera: Stathmopodidae), is important, for reducing damage to persimmon (Diospyros kaki Thunb.), an important tree fruit cultivated in Korea. In this regard, the early and precise detection of adult S. masinissa is desirable. In this study, we report the effect of (E4,Z6)-4,6-hexadecadienal (E4,Z6-16Ald) with sex pheromone com ...

Abstract:
... Management of excessive feral horse (Equus ferus caballus) and burro (Equus asinus) populations in the United States and globally has been a controversial subject for decades. I reviewed all available US federal feral horse and burro daily gather reports from 2010 to 2019 to extract equine species, technique (bait trapping or helicopter gathering), reason (emergency or other), number gathered, num ...

Abstract:
... We devised a way to distinguish separate visits by animals to a camera station. The probability that an image of a long-nosed potoroo (Potorous tridactylus) would occur declined with time since the last potoroo image, reaching an asymptote after 5min at a level that may represent the probability of initiation of new visits. ...

Abstract:
... Drosophila suzukii (spotted‐wing drosophila) spread rapidly during the first decade of the 2000s and then became widely distributed in Europe except for eastern countries. In Hungary, it was detected in 2012 for the first time, but its distribution in the eastern part of the country had been not studied. During the present investigation nine sampling sites in the north‐eastern part of the Carpathi ...
... The use of insect markers, such as fluorescent powders, is a useful tool for studying ecological and epidemiological questions. Evaluating their effect on vectors of human disease agents, such as the invasive mosquito vector Aedes aegypti (Linnaeus), is crucial for their practical and reliable use, especially in parameters linked to the risk of disease transmission such as adult survival, dispersa ...
