Comparative genomics of the miniature wasp and pest control agent Trichogramma pretiosum. [PDF]

BMC Biol, 2018
Background Trichogrammatids are minute parasitoid wasps that develop within other insect eggs. They are less than half a millimeter long, smaller than some protozoans.

Transferability of microssatellite markers to Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae)

Revista de Ciências Agroveterinárias, 2022
The biological pest control has expanded in Brazil with the Trichogramma pretiosum as the main natural enemy. The microsatellite molecular markers Simple Sequence Repeat (SSR) have been the most used, as they are multiallelic, robust and reproducible ...

Mitochondrial Genomes of Two Asexual Trichogramma (Hymenoptera: Trichogrammatidae) Strains and Comparison with Their Sexual Relatives. [PDF]

Insects, 2022
Despite its substantial costs, sexual reproduction dominates in animals. One popular explanation for the paradox of sex is that asexual reproduction is more likely to accumulate deleterious mutations than sexual reproduction.

Functional response of Trichogramma pretiosum on Trichoplusia ni eggs at different temperatures and egg densities [PDF]

Pesquisa Agropecuária Brasileira, 2018
: The objective of this work was to determine the functional response of the parasitoid Trichogramma pretiosum on Trichoplusia ni eggs at different temperatures (20, 25, and 30ºC) and egg densities (5, 10, 15, 20, 25, and 30 eggs).

Posterior concentration of Wolbachia during the early embryogenesis of the host dynamically shapes the tissue tropism of Wolbachia in host Trichogramma wasps. [PDF]

Front Cell Infect Microbiol, 2023
IntroductionThe bacterial endosymbiont, Wolbachia spp. induce thelytokous parthenogenesis in certain parasitoid wasps, such as the egg parasitoid wasps Trichogramma spp.

Evolution of five environmentally responsive gene families in a pine‐feeding sawfly, Neodiprion lecontei (Hymenoptera: Diprionidae)

Ecology and Evolution, Volume 13, Issue 10, October 2023., 2023
We examine the predictability of gene family size changes in the pine tree specialist Neodiprion lecontei. Overall, our results are consistent with predictable gene family expansions and contractions in response to novel selection pressures. Abstract A central goal in evolutionary biology is to determine the predictability of adaptive genetic changes ...

More to legs than meets the eye: Presence and function of pheromone compounds on heliothine moth legs

Journal of Evolutionary Biology, Volume 36, Issue 5, Page 780-794, May 2023., 2023
In this study, we investigated chemicals in leg extracts of three heliothine moth species (Chloridea (Heliothis) virescens, Chloridea (Heliothis) subflexa and Helicoverpa armigera). Identical pheromone compounds were present on the legs in both sexes of all three species, with no striking interspecies or intersex differences.

Diurnal temperature amplitude affects diamondback moth adult and next‐generation traits

Journal of Applied Entomology, Volume 147, Issue 1, Page 63-71, February 2023., 2023
Abstract Temperature fluctuation is one of the most important factors in climate change, and research into its effects on organisms is increasing. Nonetheless, few studies have addressed its effects on insects and particularly on the parental generation.

Field margins and botanical insecticides enhance Lablab purpureus yield by reducing aphid pests and supporting natural enemies

Journal of Applied Entomology, Volume 146, Issue 7, Page 838-849, August 2022., 2022
Abstract Botanical insecticides offer an environmentally benign insect pest management option for field crops with reduced impacts on natural enemies of pests and pollinators while botanically rich field margins can augment their abundance. Here, we evaluated the non‐target effects on natural enemies and pest control efficacy on bean aphids in Lablab ...
