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,

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 ...

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.

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 ...

Humidity modifies species‐specific and age‐dependent heat stress effects in an insect host‐parasitoid interaction

Ecology and Evolution, Volume 14, Issue 7, July 2024.
Understanding how species and their interactions respond to extreme heat events is important to evaluate the impact of climate change. Using a well‐established host‐parasitoid system, we show that the life history responses of hosts and parasitoids to heat waves can largely depend on humidity levels. Abstract Climate change is projected to increase the

Effect of sublethal concentrations of the bioinsecticide spinosyn treatment of Trichoplusia ni eggs on the caterpillar and its parasitoid, Trichogramma brassicae

Pest Management Science, Volume 80, Issue 6, Page 2965-2975, June 2024.
Eggs of the pest caterpillar Trichoplusia ni were exposed to sublethal concentrations of the bioinsecticide spinosyn. In the hatched caterpillars, genes encoding proteins involved in detoxification strategies were upregulated. Trichogramma brassicae wasps that emerged from these eggs had larger tibia length and wing area, suggesting higher performance.

Hymenopteran parasitoids of fall armyworm (Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)) in Australia, with the description of five new species in the families Braconidae and Eulophidae

Austral Entomology, Volume 63, Issue 2, Page 136-174, May 2024.
Abstract Fall armyworm, Spodoptera frugiperda (J.E. Smith) is an invasive pest of agricultural crops including sweet corn and maize. The moth was first recorded in Australia in January 2020 and is now considered established in most states and territories, and research is underway to develop management strategies. Extensive rearing of S.

RESPONSE OF TRICHOGRAMMA PRETIOSUM FEMALES TO VOLATILE SYNOMONES FROM TOMATO PLANTS1,2

, 1985
Volatile synomones in tomato plants stimulate search behavior in Trichogramma pretiosum Riley, resulting in increased rates of parasitization in both the laboratory and field. In a Y-tube olfactometer, female T.

Ocorrência de Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) em ovos de Bonagota cranaodes (Meyrick) (Lepidoptera: Tortricidae) em macieira Occurrence of Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) on eggs of Bonagota cranaodes (Meyrick) (Lepidoptera: Tortricidae) in apple tree

Revista Brasileira de Fruticultura, 2004
A lagarta-enroladeira Bonagota cranaodes (Meyrick) é nativa da América do Sul, sendo importante praga em macieira no Brasil. O controle é realizado exclusivamente com inseticidas, e o controle biológico é pouco explorado, motivo pelo qual há necessidade ...
