Abstract

The present invention discloses a pesticide main agent for controlling erythrina indica ichneumonid and preparation made up by using said main agent. Said main agent mainly contains (by wt%) 5.0-40.0% of quinalphos and 1.0-30.0% of methomyl. Said main agent can be made into emulsifiable concentrate, microeumulsion and emulsion in water.

Description

technical field [0001] The invention relates to a main pesticide agent for controlling Erythrina chinensis and the preparation thereof. Background technique [0002] Quadrastichus erythrinae Kim belongs to the family Eulophidae, the subfamily Tetrasticchinae, and the genus Quadrastichus. It is a new species published internationally in 2004. [0003] On July 25, 2005, the mainland of my country first discovered the dangerous pest Erythrina spp. Its reproductive ability is strong, and adults can mate soon after emergence. Before laying eggs, females pierce the epidermis of the host with the ovipositor, and lay eggs in the epidermal tissue of new leaves, petioles, twigs or young shoots of the host. After hatching, the larvae Feeds on mesophyll tissue, most of the galls on the leaves have only 1 larva, and a few galls have 2 larvae; the number of larvae in the stem, petiole and new branch tissues can reach more than 5. The larvae complete their development and pupate in the ...
