Potential of endophytic Beauveria bassiana against Coraebus (Coleoptera: Buprestidae) oak borers
Pest Management Science, EarlyView.This study demonstrates that an endophytic, oak‐associated strain of Beauveria bassiana exhibits adaptations to Quercus plants and potential against Coraebus boring beetles, supported by distinctive biological traits. Abstract BACKGROUND Oak borers in the genus Coraebus, including the bark‐ and the wood‐boring beetles C. florentinus and C. undatus, are

Pest Management Science, EarlyView.The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Influence of Strip-Mining on the Mortality of a Wetland Caddisfly, \u3ci\u3eLimnephilus Indivisus\u3c/i\u3e (Trichoptera: Limnephilidae). [PDF]
, 2017 A coal mine about 2.2 km upstream from Stillfork Swamp Nature Preserve, Carroll Co., Ohio was suspected of causing a reduction in Limnephilus indivisus caddisflies in the south half of the preserve. Second instar L.

Pest Management Science, EarlyView.Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Cumulative effect of HaNPV against Helicoverpa armigera infesting Chickpea
Environment Conservation Journal, 2016 The instar-wise larval mortality in H. armigera due to HaNPV @ 0.500 ml/l showed a consistent decrease in all the five instars and cent per cent larval mortality was recorded in the first instar larvae.

Foodplant Processing Adaptations in Four \u3ci\u3eHyalophora\u3c/i\u3e Species (Lepidoptera: Saturniidae): Regional and Taxonomic Specialization [PDF]
, 2017 To determine whether local populations of four Hyalophora species (Lepidoptera: Satumiidae) had improved survival or were physiologically adapted for rapid and/or efficient growth on their local hosts, a series of larval feeding studies were conducted ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Pest Management Science, EarlyView.Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Cold tolerance of third-instar Drosophila suzukii larvae
Journal of Insect Physiology, 2017 Drosophila suzukii is an emerging global pest of soft fruit; although it likely overwinters as an adult, larval cold tolerance is important both for determining performance during spring and autumn, and for the development of temperature-based control methods aimed at larvae. We examined the low temperature biology of third instar feeding and wandering

Survey of the Reduviidae (Heteroptera) of Southern Illinois, Excluding the Phymatinae, With Notes on Biology [PDF]
, 2018 A survey of the nonphymatine reduviids of southern Illinois was conducted from April 1996 to November 1998. In addition to county distributions, information was collected on times of occurrence of adults and nymphs and associated habitats.

Pest Management Science, EarlyView.XXXX Abstract BACKGROUND Spodoptera frugiperda, commonly known as the fall armyworm, is a highly economically significant pest that affects various crops, resulting in substantial losses in productivity. Managing this pest primarily relies on chemical insecticides; however, the repeated development of resistance to these chemicals has rendered them ...
