Estimation of the competitiveness of Ephedrus plagiator in relation to other parasitoids from the subfamily Aphidiinae [PDF]

Archives of Biological Sciences, 2020
The parasitoid species Ephedrus plagiator (Nees, 1811) (Hymenoptera: Aphidiinae) is one of the most important biological agents against pest aphids. We investigated whether this species was in competition with some other aphidiine species for the same ...

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.

Female-induced increase of host-plant volatiles enhance specific attraction of aphid male Dysaphis plantaginea (Homoptera: Aphididae) to the sex pheromone

, 2009
All aphid species studied so far share the same sex pheromone components, nepetalactol and nepetalactone. Variation by different enantiomers and blends of the two components released by different aphid species are limited and can only partially explain ...

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

Pest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.
