Rapid evolution and genetic basis of spinetoram resistance in Phthorimaea absoluta: evidence from six years of monitoring and laboratory selection

open access: yesPest Management Science, EarlyView.
Resistance to spinetoram in Phthorimaea absoluta is rapidly selected and functionally recessive at field‐relevant concentrations. Metabolic detoxification contributes partially, while cross‐resistance to spinosad and increased susceptibility to diamides and isoxazolines highlight practical options for resistance monitoring and insecticide rotation ...

Economic Impacts of the U.S. Soybean Aphid Infestation: A Multi-Regional Competitive Dynamic Analysis [PDF]

open access: yes
We estimated the economic benefits resulting from controlling soybean aphid infestation by using a multi-regional competitive dynamic equilibrium model. Results indicate that the reduction of soybean production resulting from a soybean aphid infestation ...

Characterisation of aphid antixenosis in aphid-resistant ancestor wheat, Triticum monococcum [PDF]

open access: yes
BACKGROUND: Due to the increasing presence of insecticide resistance across cereal aphid populations, new aphid management strategies, including the engineering of host resistance to aphids into commercial wheat varieties, are required.

RNA interference of the ecdysone receptor gene AgEcR in a wolfberry ‐ specialized strain of Aphis gossypii Glover affects its survival and fecundity and confers resistance in transgenic goji (Lycium barbarum L.)

open access: yesPest Management Science, EarlyView.
AgEcR, an ecdysone receptor from Aphis gossypii, is an RNA interference (RNAi) target. Artificial diet screening of five double ‐ stranded RNA fragments identified dsAgEcR2 targeting the D/E junction as the most potent. Transgenic goji expressing dsAgEcR2 caused molting defects and reduced fecundity, suppressing population growth and offering a ...

Assessment of insecticide use practices in licensed pest control operators in North Carolina

open access: yesPest Management Science, EarlyView.
A statewide survey of 105 licensed North Carolina pesticide operators found ants, mosquitoes, and aphids as top target pests, pyrethroids as the dominant insecticide class (68%), and limited resistance monitoring, establishing a baseline for future insecticide resistance management and outreach.

The influence of age on reproductive performance of the predatory ladybird beetle, Propylea dissecta

open access: yesJournal of Insect Science, 2004
The influence of age on reproductive performance of an aphidophagous ladybird beetle, Propylea dissecta was examined using male and female beetles of varying ages (1-30 days) after a single mating stimulus.

Epidemiology of aphid-transmitted plant-virus diseases

open access: yes, 1967
Aphids are notorious vectors of plant viruses. This role is facilitated by their method of feeding, by their enormous fecundity, and by their varied migration patterns.

Automatic insect identification, counting, and monitoring techniques: a review

open access: yesPest Management Science, EarlyView.
Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...

La biosynthèse des isoprénoïdes chez les pucerons : une cible potentielle de nouveaux bio-insecticides ? [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2008
Isoprenoid metabolism in aphids: a new target for bio-insecticides development? Currently, the control of aphids is largely dependent on the use of broad-spectrum chemical insecticides.
