Variation in Escape Behavior of Red and Green Clones of the Pea Aphid [PDF]
, 2018 Many insect species have evolved a number of antipredator tactics among which the animal can choose when attacked by a natural enemy. While it is known that individuals may differ in how the antipredator tactics are employed, quantitative studies are ...

Host choice and host leaving in Rhopalosiphum padi (Hemiptera: Aphididae) emigrants and repellency of aphid colonies on the winter host [PDF]
, 2000 Host choice and winter-host leaving in emigrants of bird cherry–oat aphid, Rhopalosiphum padi (Linnaeus), were investigated in the laboratory. In settling choice tests, emigrants collected from the winter host, Prunus padus, preferred this plant over ...

International Journal of Biological Innovations, 2022 A field trial was conducted during two rabi cropping seasons 2017-18 and 2018-19 to evaluate the role of some field crops as guard plants in pea crop. Sorghum, bajra and maize were cultivated at the boundaries of target crop (pea crop) to explore their ability to attract pea aphids (Acyrthosiphon pisum Harris) away from pea crop.

Interspecific differences of ladybirds (Coleoptera: Coccinellidae) in their repellency to ants
Journal of Zoology, Volume 327, Issue 1, Page 73-83, September 2025.Our study found that, unlike those from mealworms, compounds in whole‐body extracts of ladybirds effectively deterred ants. No correlation was found between the degree of aposematic colouration (highly conspicuous vs. less conspicuous) and repellence. Mycophagous ladybird species exhibited levels of protection comparable to predatory species, and large

Aphids associated with shrubs, herbaceous plants and crops in the Maltese Archipelago (Hemiptera, Aphidoidea) [PDF]
, 2011 A survey of the aphids associated with Maltese shrubs, herbaceous plants and crops was carried out. Sixty six aphid species were recorded from more than 90 species of host plants.

Discharge of Conidia of Entomophthora thaxteriana Petch from the Pea Aphid Acyrthosiphon pisum Harris [PDF]
Journal of General Microbiology, 1971 SUMMARY: At 21°, conidia of Entomophthora thaxteriana were first discharged from infected pea aphids about 6 to 9 h. after the aphids died and the rate of discharge was highest during a short period about 9 h. later. In constant light, the rate then decreased and discharge ended about 36 h. after an infected aphid died; in constant darkness the maximum

Agricultural and Forest Entomology, Volume 27, Issue 3, Page 463-475, August 2025.Abstract Invasive eucalypt psyllids pose a threat to the long‐term production of eucalypts worldwide. In order to reduce their economic impact, classical biological control using Psyllaephagus species has been used successfully. The objectives of this study were to determine the host specificity and host stage preference of Psyllaephagus blastopsyllae,

Chromosomal mapping reveals a dynamic organization of the histone genes in aphids (Hemiptera: Aphididae) [PDF]
, 2013 Despite their involvement in different processes, histone genes have been analysed in few insects. In order to improve the knowledge about this important gene family, genes coding for histones have been analysed in the aphid Acyrthosiphon pisum showing ...
