The life table statistics of six native Kenyan species/strains of Trichogramma and Trichogrammatoidea were established using a factitious host Corcyra cephalonica, Stainton (Lepidoptera: Pyralidae), at eight different temperatures (10, 15, 20, 25, 28, 30, 32 and 35 degrees C) and two humidity levels (40-50 and 70-80%). The objective was to select insects with superior attributes for augmentativ...

Trichogramma wasps are tiny parasitoids of lepidopteran eggs, used extensively for biological control. They are often infected with the bacterial symbiont Wolbachia, which converts Trichogramma to an asexual mode of reproduction, whereby females develop from unfertilized eggs. However, this Wolbachia-induced parthenogenesis is not always complete, and previous studies have noted that infected f...

Abstract We study a natural contact instanton equation on gauge fields over 7-dimensional Sasakian manifolds, which is closely related to both the transverse Hermitian Yang–Mills (HYM) condition and G2-instanton equation. obtain, by Fredholm theory, finite-dimensional local model for moduli space of irreducible solutions. Following approach Baraglia Hekmati in five dimensions [1], we derive coh...

the aphidiine parasitoids (hym., braconidae) attacking the pest aphids on various pome and stone fruit trees in different parts of iranwere studied. a total of 13 species belonging to seven genera of aphid parasitoids were identified in association with 17 aphid species on 10 different species of fruit trees. sixty nine tritrophic associations were detected from the studied area of which 25 ass...

Trichogramma, an egg parasitoid can be used in controlling many lepidopteran pests. Therefore, it is necessary to demonstrate the capacity of these natural enemies in controlling the pest population so as to use them in biological control programs against the pest. Such an attempt was made in this particular study, where the parasitization rate of Trichogramma chilonis was tested on the eggs of...

Unisexual Trichogramma forms have attracted much attention due to their potential advantages as biocontrol agents. Fitness studies have been performed and understanding the cost that Wolbachia may inflict on their hosts will help in deciding if Wolbachia infected (unisexual) forms are indeed better than sexual forms when used in biological control programmes. The influence of Wolbachia on the f...
