In the Atlas cedar forests located on northern massifs of Blidean and at eastern extension Saharan Atlas, 79 egg batches processionary moth Thaumetopoea pityocampa (Denis & Schiffermuller, 1775) were collected during summer period from two sites: Chrea National park (46), Ouled Yagoub forest (33). To assess effect characteristics parasitism, eggs monitored after hatching larvae and/or emerg...

Twenty-seven Trichogramma and Trichogrammatoidea species or strains of different origin were tested on diamondback moth (Plutella xylostella (L.)) for host acceptance and host suitability. The experiments were conducted at 27 ± 2oC and 75-90% RH. Depending on their initial parasitization activity, the number of offspring produced and emergence ratio, 18 Trichogramrna species were identified as ...

Wolbachia (Hertig) endosymbionts are extensively studied in a wide range of organisms and are known to be transmitted through the egg cytoplasm to the offsping. Wolbachia may cause several types of reproductive modifications in arthropods. In Trichogramma species, parthenogenesis-inducing Wolbachia bacteria allow females wasps to produce daughters from unfertilized eggs and these bacteria are p...

the codling moth, cydia pomonella, is the most important pest insect in apple orchards. efficacy of a native strain of the egg parasitoid wasp, trichogramma embryophagum, was statistically compared with chemical control and check treatments in an apple orchard. the best times for releasing the parasitoid wasps were determined by using a forecasting model based on estimation of growing degree ho...

Trichogramma spp. (Hymenoptera Trichogrammatidae) are endoparasitic wasps that attack the eggs of mainly Lepidoptera species. The morphology of the antennal multiporous gustatory sensilla of five Trichogramma species is studied and compared: Trichogramma cacoeciae Marchal, Trichogramma chilonis Ishii, Trichogramma dendrolimi Matsumura, Trichogramma turkestanica Meyer, and Trichogramma sibericum...

Cydia pomonella is a major pest in apples in Denmark. Trichogramma spp. are known biocontrol agents of C. pomonella eggs and two naturally occurring species in Denmark, which are also both commercially available, were chosen for mass-release trials. Trichogramma evanescens, T. cacoeciae or a mix of the two species were evaluated for mass-release to control C. pomonella in two commercial organic...
