Response of Trichogramma brassicae to increasing temperature using molecular and biological methods [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2023
The increase in the earth temperature is one of the latest problems threatening the earth ecosystem. Insects as poikilothermic organisms have a high dependence on their environment's temperature so increasing global temperature makes impressions on their

Evaluation of asexual Wolbachia-infected Trichogramma brassicae performance in greenhouse and field conditions [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2023
In some Trichogramma species, parthenogenesis is mostly induced by intracellular symbiotic Wolbachia bacteria. Populations of this egg parasitoid wasp that produce more female progeny can potentially have higher fitness.

The performance of Trichogramma (Hymenoptera: Trichogrammatidae) Parasitoids Feeding on Honey Sources

open access: yesJournal of Agricultural Sciences, 2021
The effectiveness of parasitoids as organism for biological control is at times limited by food sources. Most of parasitoids rely on carbohydrate foods to enhance their longevity and reproductive capacity.

The state of commercial augmentative biological control: plenty of natural enemies, but a frustrating lack of uptake [PDF]

open access: yes, 2011
Augmentative biological control concerns the periodical release of natural enemies. In com- mercial augmentative biological control, natural enemies are mass-reared in biofactories for release in large numbers to obtain an immediate control of pests. The

Interaction of exogenous factors (light and temperature) in their influence on the daily pattern of adult eclosion in Trichogramma embryophagum (Hymenoptera: Trichogrammatidae)

open access: yesEuropean Journal of Entomology, 2002
A comparative study of the direct influence of single, non-repetitive changes of light and/or temperature on the daily pattern of adult eclosion was conducted in laboratory conditions with the egg parasitoid, Trichogramma embryophagum (Hartig).

Maternal age and endogenous variation in maternal influence on photoperiodic response in the progeny diapause in Trichogramma embryophagum (Hymenoptera: Trichogrammatidae)

open access: yesEuropean Journal of Entomology, 2002
A laboratory study was carried out on photoperiodic control of prepupal diapause in the egg parasitoid Trichogramma embryophagum (Hartig). All experiments were conducted with an isofemale parthenogenetic strain. The maternal generation was reared at 20°C
