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

Entomologia 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.

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

MicrobiologyOpen, 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 ...

The American cocoa pod borer, Carmenta foraseminis, an emerging pest of cocoa: A review El barrenador americano de la mazorca de cacao, Carmenta foraseminis, una plaga emergente del cacao: una revisión

Agricultural and Forest Entomology, Volume 27, Issue 3, Page 340-356, August 2025.
Abstract This review provides a synthesis of the available knowledge on Carmenta foraseminis, an emerging cocoa pest in northern South America. This moth was first described in 1995 in Panama, and its proliferation across the Amazon basin is currently threatening the production of cocoa in the region and may endanger the sector's sustainability. Hence,

What is the potential for artificial selection of insect biological control traits? A systematic review of their genetic variation, heritability, and evolvability

Entomologia Experimentalis et Applicata, Volume 173, Issue 6, Page 463-497, June 2025.
Growing interest in optimizing biocontrol traits, particularly due to Nagoya Protocol constraints, necessitates understanding their heritability and genetic variation. This systematic review of 5209 studies on arthropod biocontrol agents yielded 94 relevant articles, with 42 providing heritability values.

SELECTIVITY OF REGISTERED AGROCHEMICALS FOR SOYBEANS AIMING IMMATURE PHASES OF TRICHOGRAMMA PRETIOSUM [PDF]

, 2022
The aim of this study was to evaluate the effects of agrochemicals registered for soybean on parasitoid Trichogramma pretiosum in immature stages. Bioassays were conducted in the laboratory by exposing eggs parasited, using the methods proposed by the ...

DNA methylase 1 influences temperature responses and development in the invasive pest Tuta absoluta

Insect Molecular Biology, Volume 33, Issue 5, Page 503-515, October 2024.
Dnmt1 regulates the adaptability of tomato leaf miner to temperature. TaDnmt1 RNAi impacts the larval growth and development, resulting in a significant increase (57%) in larval mortality and decrease in pupation (49.3%) and pluming (50.9%). The rapid geographic expansion of Tuta absoluta infestation is closely associated with TaDnmt1‐mediated ...

Demographic parameters of the indigenous egg parasitoids, Trichogramma spp., parasitizing the invasive tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)

Egyptian Journal of Biological Pest Control, 2019
Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), one of the most destructive pests of tomato, has recently invaded India. Before recommending any bio-control agent for its control, it is important to study the demographic parameters of the bio-agent ...
