Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest 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.

Profiling insecticide resistance phenotypes and genotypes in Aedes aegypti populations across four regions in Puerto Rico

open access: yesScientific Reports
Vector-borne diseases exert a considerable toll on global health. The efficacy of vector control strategies is being threatened by the emergence and spread of insecticide resistance worldwide.

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

open access: yesPest Management Science, EarlyView.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Susceptibility of Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae) to novel and established insecticides in Brazil: resistance survey, baseline, and implications for management

open access: yesPest Management Science, EarlyView.
Baseline susceptibility of Phthorimaea absoluta to novel insecticides isocycloseram and tolfenpyrad was established in Brazil. Diagnostic doses were proposed for early resistance detection. Early tolfenpyrad tolerance and abamectin‐driven cross‐tolerance to isocycloseram via oxidases highlight cross‐resistance risks, emphasizing the need for routine ...

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields

open access: yesPest Management Science, EarlyView.
This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management

Insights into the role of non-coding RNAs in the development of insecticide resistance in insects

open access: yesFrontiers in Genetics
Pest control heavily relies on chemical pesticides has been going on for decades. However, the indiscriminate use of chemical pesticides often results in the development of resistance in pests. Almost all pests have developed some degree of resistance to

A systematic review of insecticide resistance in Aedes aegypti (Diptera: Culicidae) and implications for dengue control in Indonesia [PDF]

open access: yesVeterinary World
Background and Aim: Dengue fever, primarily transmitted by Aedes aegypti, remains a critical public health challenge in Indonesia, with periodic outbreaks exacerbated by widespread insecticide resistance.

Revisiting the Impact of Bt Corn Adoption by U.S. Farmers [PDF]

open access: yes
This study examines the impact of adopting Bt corn on farm profits, yields, and insecticide use. The study employs an econometric model that corrects for self-selection and simultaneity.

Bifenthrin Baseline Susceptibility and Evaluation of Simulated Aerial Applications in \u3ci\u3eStriacosta albicosta\u3c/i\u3e (Lepidoptera: Noctuidae) [PDF]

open access: yes, 2019
Striacosta albicosta (Smith) is a maize pest that has recently expanded its geographical range into the eastern United States and southeastern Canada. Aerial application of pyrethroids, such as bifenthrin, has been a major practice adopted to manage this
