Selection of Effective Species or Strains of Trichogramma Egg Parasitoids of Diamondback Moth
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 ...
متن کاملSequence among Strains ofActinomyces spp
The nucleotide sequence of the Actinomyces viscosus T14V sialidase gene (nanH) and flanking regions was determined. An open reading frame of 2,703 nucleotides that encodes a predominately hydrophobic protein of 901 amino acids (Mr, 92,871) was identified. The amino acid sequence at the amino terminus of the predicted protein exhibited properties characteristic of a typical leader peptide. Five ...
متن کاملMorphology and distribution of antennal multiporous gustatory sensilla related to host recognition in some Trichogramma spp
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...
متن کاملHost-foraging success of three species of Trichogramma (Hymenoptera: Trichogrammatidae) in a simulated retail environment.
Three species of trichogrammatid egg parasitoids (Trichogramma deion Pinto & Oatman, Trichogramma ostriniae Pang & Chen, and Trichogramma pretiosum Riley) (Hymenoptera: Trichogrammatidae) were evaluated under laboratory conditions as potential biological control agents for the Indianmeal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), on retail shelves. A single shelving unit was...
متن کاملEffects of Intra- and Interpatch Host Density on Egg Parasitism by Three Species of Trichogramma
Host-foraging responses to different intra- and interpatch densities were used to assess three Trichogramma spp. (Hymenoptera: Trichogrammatidae) Trichogramma deion Pinto and Oatman, T. ostriniae Pang and Chen, and T. pretiosum Riley - as potential biological control agents for the Indian meal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae). Single naïve females were allowed 6 h to ...
