Insect oviposition in herbaceous plants attracts egg parasitoids despite fungal phytopathogen infection

open access: yesBiological Control
Egg parasitoids are important natural enemies of several insect pests. The ability to kill the pest before it can inflict damage to the plant makes egg parasitoids ideal candidates for biological control.

First report of Trichogramma danausicida and Trichogramma cacaeciae reared from Thaumatotibia leucotreta eggs in Israel

open access: yesZooKeys, 2018
The egg parasitpoids Trichogramma danausicida (Nagaraja) and Trichogramma cacaeciae (Marchal) (Hymenoptera: Trichogrammatidae), are reported for the first time in Israel. Moreover, our discovery of T.

Guidelines for Immunomodulatory Assays of Food Bioactives on Drosophila melanogaster Model

open access: yesFuture Postharvest and Food, EarlyView.
Guidelines are proposed for evaluating the immunomodulatory effects of food bioactives in Drosophila melanogaster, involving treatment with bioactives, pathogen preparation, infection routes, and immune response assessment. This model highlights the conserved mechanisms of cellular and humoral immunity for studying host‐microbe interactions.

Dinotefuran toxicity on predators and egg parasitoids of Piezodorus guildinii and Dichelops furcatus (Hemipetra: Pentatomidae) under field conditions

open access: yesPesquisa Agropecuária Tropical
Piezodorus guildinii and Dichelops furcatus stink bug populations are naturally regulated by predators and egg parasitoids. However, these natural enemies can be affected by the application of non-selective insecticides commonly employed for stink ...

Host Sex Discrimination by an Egg Parasitoid on Brassica Leaves

open access: yesJournal of Chemical Ecology, 2011
Egg parasitoids are able to find their hosts by exploiting their chemical footprints as host location cues. In nature, the apolar epicuticular wax layer of plants that consists of several classes of hydrocarbons serves as the substrate that retains these contact kairomones. However, experiments on chemical footprints generally have used filter paper as

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

A survey of egg-parasitoid species associated with Dendrolimus houi (Lepidoptera, Lasiocampidae) in Fujian, China [PDF]

open access: yesBiodiversity Data Journal
Dendrolimus houi Lajonquiere is a polyphagous defoliator with strong adaptability causing significant damage to hundreds of hectares of pine forest. The larvae primarily damage coniferous tree species.

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

open access: yesPest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Size-induced reproductive constraints in an egg parasitoid

open access: yesJournal of Insect Physiology, 2012
The size of adult parasitoids is influenced by the quantity and quality of resources available during immature development. Gregarious development of endoparasitoids results in scramble competition where the resources are shared among individuals developing into the same host.

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.)

open access: yesPest Management Science, EarlyView.
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major
