age-specific functional response of trichogramma brassicae (hymenoptera: trichogrammatidae) parasitizing different egg densities of ephestia kuehniella (lepidoptera: pyralidae)
the parasitoid trichogramma brassicae bezdenko is used for inundative releases in biological control programs against lepidopteran pests in agro-ecosystems. age-specific functional responses of t. brassicae to different egg densities (5, 10, 20, 30, 40, 60, and 80) of sterilized eggs of ephestia kuehniella at 23±1°c, 60±5% rh, and 16:8 h (l:d photoperiod ) were studied. e. kuehniella densities ...
متن کاملlnundative Release of Trichogramma for the Control of Cruciferous Lepidoptera: Preintroductory Selection of an Effective Parasitoid
Egg parasitoids of the genus Trichogramma are the most widely used natural enemy for biological pest control in the world. Their use is restricted to lepidopterous pest species. Due to relatively cheap mass rearing systems employing factitious host species, Trichogramma are usually applied for inundative biological control: repeated releases of high numbers of parasitoids aiming at a direct con...
متن کاملEffect of Host Change on Demographic Fitness of the Parasitoid, Trichogramma brassicae
Trichogramma brassicae (Bezdenko) is the most important species of Trichogramma parasitoids in Iran. The cotton bollworm, Helicoverpa armigera (Hubner) is a polyphagous insect pest that attacks many crops including cotton, maize, soybean, tomato, etc. The bollworm egg is a suitable target for many Trichogramma species. Factitious hosts such as eggs of the flour moth, Anagasta kuehniella (Zeller...
متن کاملA composite genetic map of the parasitoid wasp Trichogramma brassicae based on RAPD markers.
Three linkage maps of the genome of the microhymenopteran Trichogramma brassicae were constructed from the analysis of segregation of random amplified polymorphic DNA markers in three F2 populations. These populations were composed of the haploid male progeny of several virgin F1 females, which resulted from the breeding of four parental lines that were nearly fixed for different random amplifi...
متن کاملBiocontrol efficacy and viability of Trichogramma chilonis on Corcyra cephalonica and Spodoptera litura under laboratory conditions
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...
