INFLUENCE OF SOME INSECTICIDES ON THE EFFICIENCY OF Trichogramma SPP. (HYM., TRICHOGRAMMATIDAE ) TREATED AS IMMATURE STAGES INSIDE Sitotroga Cerealella EGGS AND INTRODUCED Pectinophora Gossypiella EGGS AFTER EMERGENCE. [PDF]

open access: yesJournal of Plant Protection and Pathology, 2015
Laboratory study was conducted to study the effect of some new insecticides on three different immature stages of three trichogrammatids and estimate its efficiency in parasitizing eggs of pink bollworm, Pectinophora gossypiella after the completion of ...

Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 436-452, May 2026.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.

Evaluation of diverse elite and landrace maize lines for testcross hybrid performance and combining ability under low and high phosphorus fertilization regimes

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract In the context of over‐fertilization, especially of phosphorus (P), the debate about the usefulness of applying starter fertilization to maize (Zea mays L.) must be revisited. One solution is to breed crops with an enhanced phosphorus use efficiency, which require less fertilizer yet are high‐yielding.

Native insect species should be selected for classroom rearings

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 1-10, January 2026.
Rearing insects in the school classroom can build positive attitudes towards insects among schoolchildren, which is becoming increasingly important as insect populations decline. Identified frequent use of non‐native insect species, raising environmental and ethical concerns after classroom rearing ends.

Comparative Genomics of the Endosymbiont Cardinium Causing Reproductive Manipulation in Encarsia Parasitoid Wasps

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
We assembled four Cardinium hertigii draft genomes: cEina3 causes cytoplasmic incompatibility, cEhis1 induces parthenogenesis, cEper2 is associated with parthenogenesis, and cEina2 infects asymptomatically. All four strains are closely related and hosted by Encarsia parasitoid wasps, but key differences exist, including their metabolic potential and ...

Suitability of Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae) as host for two local Trichogramma species (Hymenoptera: Trichogrammatidae) and possible implications on biological control programs

open access: yesJournal of Oasis Agriculture and Sustainable Development, 2021
In this study, laboratory tests were conducted to evaluate the suitability of Ectomyelois ceratoniae (Zeller) eggs as host for the development of two Trichogramma species: Trichogramma cacoeciae (Marchal) and Trichogramma bourarachae (Pintureau and ...

Attraction of Telenomus remus to Egg Volatiles of Spodoptera litura and Oviposition‐Induced Plant Volatiles From Tobacco (Nicotiana tabacum)

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
The parasitoid T. remus was attracted to OIPVs and S. litura egg volatiles. At lower concentrations of 1 and 10 ng/μL the parasitoid showed the highest attraction. The binary combinations of linalool (L) with tetracosane (T) and linalool (L) with cis‐3‐hexenyl acetate (C) strongly attracted the parasitoids.
