Apr 01, · ► The toxicities of 30 insecticides to adult Trichogramma nubilale were evaluated. ► The insecticides tested showed different degree of toxicity to T. nubilale. ► Organophosphates and carbamates had the highest intrinsic toxicity to T. nubilale. ► The insect growth regulators exhibited the least toxicity. ► The other four chemical groups induced Cited by: Sep 01, · The ovarian cycle was studied in two species ofTrichogramma, the thelytokousT. cacoeciae and the arrhenotokousT. brassicae. For both species, egg development was recorded (1) in the immature stages (2) in adult females before and after one bout of oviposition. The two species differed in the numbers of immature eggs formed and stored in the ovaries, and in the Cited by:
Trichogramma adult Trichogramma are essential for controlling moth species which affect agricultural plants at some point during the growing season. Moths are adult insects that usually feed on nectar produced by plants and honeydew produced by certain insects. PRODUCT DESCRIPTIONS: Egg-laying adult Trichogramma brassicae, platner/iminutum, and pretiosum, are Moth Egg Parasitoids capable of moth control as well as caterpillar control. These mm. mini-wasps are effective Lepidopteran egg parasitoids. Lepidoptera (lep-ih-DOP-ter-rah) is the name of the order that moths and butterflies belong to.
Trichogramma are shipped (as pupae) inside of grain moth eggs ready to emerge as adults. They can be loose or glued to perforated cards. Loose eggs can be divided into paper cups or other containers; there are approximately 20, eggs in a cubic centimeter (ml). Shipped as pupae in host eggs, glued to one inch by one inch paper squares, Trichogramma arrive ready to hatch out as adult wasps. Release when moths are first present and periodically thereafter. Release 5, (1 square) per 5, square feet weekly, for weeks.
