Green peach aphids (Myzus persicae) maintained on different host plants (bok choy, clover and potato) for 15 generations were evaluated on each host plant to understand the impacts of within‐generational and cross‐generational effects on their performance.

The pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae), shows wing polyphenism (winged and wingless morphs) in its life cycle. The winged morph is adapted for dispersal; its two developmental adult stages (for dispersal and reproduction) are ...

The reproductive system of the male and oviparous female of a model organism—the pea aphid, Acyrthosiphon pisum (Hemiptera, Aphididae) [PDF]
The structure of the reproductive system of the sexual generation—males and oviparous females—of the pea aphid Acyrthosiphon pisum (Harris) (Hemiptera, Aphididae), a serious pest of cultivated plants of Fabaceae, was investigated.

Abstract The presence of predators can induce non‐consumptive effects on prey that result in subsequent changes to prey behaviour and defence. We investigate the interaction between top‐down non‐consumptive effects of various stages of the predator Coccinella septempunctata L.(Coleoptera: Coccinellidae) (larvae and adult) and bottom‐up effects of host ...

Effect of Host-plant on the Resistance of Acyrthosiphon pisum (Harris) to Insecticides
SummaryBy means of a laboratory spraying technique, ten comparisons were made of the resistance to rotenone of samples of adult apterous viviparous parthenogenetic females of the Pea Aphid, Acyrthosiphon pisum (Harris), reared on broad bean and on clover, respectively.

To attract mates, several coleopteran taxa release volatile sex pheromones via a behaviour termed calling. We studied a postulated calling behaviour in the seven‐spot ladybird Coccinella septempunctata L. for the first time. We also investigated the effects of immediate mating history and the presence of conspecifics on calling behaviour.

A barley cysteine-protease inhibitor reduces teh performance of two aphid species in artificial diets and transgenic arabidopsis plants [PDF]
Cystatins from plants have been implicated in plant defense towards insects, based on their role as inhibitors of heterologous cysteine-proteinases. We have previously characterized thirteen genes encoding cystatins (HvCPI-1 to HvCPI-13) from barley ...

ABSTRACT The use of substrate borne vibrational playback to control insect pests is a rapidly growing line of research targeting many problematic species. Among the control approaches currently being tested, vibrational deterrent playbacks that aim to prevent feeding and to drive pests away from the target area are comparatively under‐explored.
