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

Pest 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)

Pest 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

Pest 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

Wheat fertilization affects oviposition preference of wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae)

Pest Management Science, EarlyView.
Wheat fertilization increased plant growth, nitrogen and protein levels, influencing the wheat volatile profile and affecting female wheat midge choice to lay eggs. This could partly result from the observed changes in the VOC profile. Abstract BACKGROUND In Canada, the orange wheat blossom midge (hereafter called wheat midge), Sitodiplosis mosellana ...

Investigating zeta‐cypermethrin resistance stability in California Drosophila suzukii populations

Pest Management Science, EarlyView.
After continuous selection and removal of selection pressure in spotted‐wing Drosophila, zeta‐cypermethrin resistance remained stable over several generations. Following a population bottleneck, zeta‐cypermethrin resistance increased without selection, highlighting the importance of insecticide rotation.

Small molecules as arthropod kinin receptor antagonists, feeding modulators, or novel mosquitocidal agents

Pest Management Science, EarlyView.
A two‐pronged screen of small molecules – (1) on recombinant kinin receptor and (2) through topical application – identifies kinin receptor antagonists, feeding behavior modulators, and new mosquitocidal molecules. Abstract BACKGROUND Aedes aegypti and Culex quinquefasciatus mosquitoes are primary vectors for numerous human and animal pathogens and ...

Key agronomic and ecological factors impacting moth borers populations and their natural enemies in the context of sugarcane expansion and intensification. : S1012TU02 Integrated Pest Management [PDF]

, 2012
Global intensification and expansion of agricultural areas for more food and energy products is expected to change pest-plant interactions and the related ecosystem services. For example, intensification of agronomic practices, land use change, landscape
