Biotic pesticides and its pest control manner null for hamoguribae pest control

摘要

PROBLEM TO BE SOLVED: To obtain a biological agroshemical, effective in controlling a leaf miner fly resistant insecticides without adversely affecting the ecosystem and so-called gentle to the environment by using a spacific parasitic wasp as a natural enemy. ;SOLUTION: This biological agrochemical for controlling a leaf miner fly uses Hemiptarsenus varicornis which is a species parasitic wasp as a natural enemy. An imago or a chrysalis of the Hemiptarsenus varicornis is especially preferred. The parasitic wasp is obtained by making the leaf minor fly, e.g. Liriomyza Backer lay an egg on a kidney bean, providing a larva in the final instar, freeing an imago of the parasitic wasp at this time, making the parasitic wasp lay an egg on the larva of the Liriomyza congesta Becker, discoloring larva of the Liriomyza congesta Backer, whose egg was laid by the parasitic wasp, dark brown, taking out the resultant discolored larva, making the parasitic wasp eclose and parasitizing the eclosed parasitic wasp on a new larva of the Liriomyza congesta Becker. The operations are repeated to carry out the maintenance, control and proliferation of the parasitic wasp. The parasitic wasp kills the leaf miner fly by making the imago of the parasitic wasp lay the egg on the body surface of the larva of the leaf miner fly one by one and making the hatched larva of the parasitic wasp eat the larva of the leaf miner fly or sucking the humor of the larva of the leaf miner fly by the imago of the parasitic wasp.;COPYRIGHT: (C)1997,JPO
