Facultative endosymbionts of aphids on strawberry crops affect aphid-parasitoid interactions
Biological ControlAphids are major agricultural pests and laboratory studies have shown that heritable bacterial endosymbionts can protect aphids against biocontrol parasitoids, but results from agricultural crop systems are lacking. Here we assess (1) which aphid species

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

Associative odour learning affects mating behaviour in Aphidius ervi males (Hymenoptera: Braconidae)
European Journal of Entomology, 2005 We used the aphid parasitoid Aphidius ervi reared in its host Acyrthosiphon pisum to examine if male sexual attractive responses can be conditioned to an odour (vanilla) that is not present in the natural environment.

Evolutionary Relationships of Courtship Songs in the Parasitic Wasp Genus, Cotesia (Hymenoptera: Braconidae) [PDF]
, 2019 Acoustic signals play an important role in premating isolation based on sexual selection within many taxa. Many male parasitic wasps produce characteristic courtship songs used by females in mate selection.

Endophytic entomopathogenic fungi as biological control agents of insect pests
Pest Management Science, Volume 80, Issue 12, Page 6033-6040, December 2024.Interaction between plants and endophytic entomopathogenic fungi. Fungal metabolites and induced systemic resistance enhance the plant's defense mechanisms against pests and pathogens. In addition, volatile compounds emitted by the plants colonized by endophytic entomopathogenic fungi play an important role in recruiting natural enemies of insect pests,

Parasitic wasp responses to symbiont-based defense in aphids
BMC Biology, 2012 Background Recent findings indicate that several insect lineages receive protection against particular natural enemies through infection with heritable symbionts, but little is yet known about whether enemies are able to discriminate and respond to ...

Heat wave impacts on crop‐pest dynamics are dependent upon insect ontogeny and plant resistance
Ecosphere, Volume 15, Issue 10, October 2024.Abstract Heat waves, brief periods of unusually high temperatures, are damaging to agroecosystems and are increasing in frequency and intensity due to climate change. Despite growing appreciation for the threat that heat waves pose to agricultural sustainability, we have a poor understanding of what determines their impact on agroecological ...
