Trichogramma Westwood (Hymenoptera: Trichogrammatidae) cause high mortality rates in the potentially resistant pest species, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), and are considered integral to the resistance management plan for Bacillus thuringiensis transgenic cotton, Gossypium hirsutum L., production in the Ord River Irrigation Area (ORIA), WesternAustralia.Measured as perc...

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...

Abstract Background Domestication usually has negative effects on insect performance, especially when they are reared continuously for many generations. Rejuvenation can reduce the of domestication in parasitoid, Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) 30 generations (G) Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae). Life table and parasitism parameters prim...

ectomyelois ceratoniae zeller (lepidoptera.: pyralidae), is the key pest of pomegranate in iran. trichogramma wasps could be used as effective agents of biological control that can also be used effectively in ipm programs. the effect of host density on parasitism of trichogramma brassicae was studied by exposing densities of 4, 8, 10, 20, 40, 60, 80 and 120 eggs of factitious host (sitotroga ce...

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...

The cabbage moth, Mamestra brassicae L. (Lepidoptera: Noctuidae), is a serious pest of vegetable crops throughout the world. In order to determine whether or not M. brassicae is a migrant, and if yes, what is the pattern of M. brassicae seasonal migration, a long-term study on M. brassicae from April to October in 2003-2014 was carried out by means of a searchlight trap on a small island locate...

Genetic mapping is an important step in the study of any organism. An accurate genetic map is extremely valuable for locating genes or more generally either qualitative or quantitative trait loci (QTL). This paper presents a new approach to two important problems in genetic mapping: automatically ordering markers to obtain a multipoint maximum likelihood map and building a multipoint maximum li...
