Predation of nabis punctipennis on acyrthosiphon pisum in the presence of the alternative prey aphis craccivora in alfalfa
(Universidad de Concepción, 2020)
The feeding behavior of the generalist predator Nabis punctipennis Blanchard (Nabidae) on Acyrthosiphon pisum Harris (Aphididae), two hemipterans common in alfalfa in Chile, was studied in a laboratory experiment using A. ...
Acceptance and suitability of Acyrthosiphon pisum and Sitobion avenae as hosts of the aphid parasitoid Aphidius ervi (Hymenoptera: Braconidae)
(Czech Academy of Sciences, 2003)
Aphidius ervi Haliday is a parasitoid of natural populations of both Acyrthosiphon pisum (Harris) on alfalfa and Sitobion avenae (Fabricius) on wheat in Chile. In this study the performance of the aphid parasitoid on both ...
Seasonal, spatial and diel partitioning of Acyrthosiphon pisum (Hemiptera: Aphididae) predators and predation in alfalfa fields
(Elsevier, 2014)
Predators are important natural enemies, often responsible for preventing pest population outbreaks of in
many crops. Complementarity in resource use involves spatial or temporal segregation of predators,
which can result ...
Behavioural thermoregulation in Acyrthosiphon pisum (Homoptera: Aphididae): The effect of parasitism by Aphidius ervi (Hymenoptera: Braconidae)
(2001)
The effects of parasitisation by Aphidius ervi on the thermoregulatory behaviour of the pea aphid Acyrtosiphon pisum were studied in alfalfa fields and in an experimental thermal gradient. In the field, mummies were found ...
