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

open access: yesEcology 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

Resposta funcional de Trichogramma pretiosum sobre ovos de Trichoplusia ni a diferentes temperaturas e densidades de ovos

open access: yes, 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).

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

open access: yesPest 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.

The role of insect cell lines in an artificial diet for the parasitold wasp, Trichogramma pretiosum

open access: yes, 2005
Trichogramma species are mass-produced for biological control using host eggs. Artificial diets have been developed to reduce production costs, however, most include insect haemolymph as a major component, which still results in a significant expense ...

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

open access: yes, 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.

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

open access: yesAustral 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.

SELEÇÃO DE ESPÉCIES DE Trichogramma sp. EM OVOS DA TRAÇA-DAS-CRUCÍFERAS, Plutella xylostella

open access: yesRevista Caatinga, 2011
Trichogramma species are found naturally parasitizing eggs of several lepidopteran species. Among the Trichogramma species, however, there is preference for certain lepidopteran species as host. Therefore, to succeed in a biological control program using

Pest risk assessment of Leucinodes orbonalis for the European Union

open access: yesEFSA Journal, Volume 22, Issue 3, March 2024.
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative risk assessment of Leucinodes orbonalis (Lepidoptera: Crambidae), the eggplant fruit and shoot borer, for the EU. The assessment focused on potential pathways for entry, climatic conditions favouring establishment, spread and impact ...

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

open access: yesRevista 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 ...
