SELEÇÃO DE ESPÉCIES DE Trichogramma sp. EM OVOS DA TRAÇA-DAS-CRUCÍFERAS, Plutella xylostella

Revista Caatinga, 2011
Trichogramma species are found naturally parasitizing eggs of several lepidopteran species. Among the Trichogramma species, however, there is preference for certain lepidopteran species as host. Therefore, to succeed in a biological control program using

Intraspecific Hybridization Improves Performance of the Biological Control Agent Hypena opulenta

Evolutionary Applications, Volume 19, Issue 8, August 2026.
ABSTRACT Introduced species often undergo genetic drift and natural selection, which can reduce genetic diversity and drive differentiation among populations. Intraspecific hybridization, outcrossing among individuals from genetically distinct groups, may counteract these effects by increasing heterozygosity, potentially improving performance. However,

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Compatibility between Entomopathogenic Fungi and Egg Parasitoids (Trichogrammatidae): A Laboratory Study for Their Combined Use to Control Duponchelia fovealis

Insects, 2020
The European pepper moth, Duponchelia fovealis (Lepidoptera: Crambidae), is a key pest in strawberry production. Entomopathogenic fungi (EF) and parasitoids of the Trichogrammatidae family are effective biological control agents of this pest with the ...

Host phenology‐driven infestation patterns of the carob moth (Ectomyelois ceratoniae) in Mediterranean walnut orchards: insights from comparison with codling moth (Cydia pomonella)

Pest Management Science, Volume 82, Issue 7, Page 6877-6889, July 2026.
In Mediterranean walnut orchards, Ectomyelois ceratoniae replaces Cydia pomonella as the primary pest. Capture peaks between packing tissue brown (PTB) stage and husk dehiscence define a critical window for monitoring and early harvest to prevent kernel infestation.
