Description
Technical field
The present invention relates to field of pesticides, and in particular to a kind of biological insecticides for preventing and treating high mountain paddy leaf roll snout moth's larva.
Background technology
Rice leaf roller is one of rice Occurrence, belongs to lepidoptera pyralidae.Rice plant of tillering stage it is aggrieved influence its just
It is frequently grown；Middle and later periods is aggrieved, influences yield and becomes apparent from, and particularly later stage sword-like leave is aggrieved, causes abortive grain rate to increase, and loss is serious.
Ovum, which dissipates, to be originated on blade, is generally more using blade back, newly hatched larvae climbs to blade tip leaf roll feeding, and slightly larger larva then pierces the leaf heart, leaf
Food mesophyll is stung on intrathecal or blade face, and spins and clove hitch bud is indulged on the both sides of leaf.After the good bud of knot just in bud along vein eat mesophyll and
Epicuticle, it is killed leaf and strip tikka different in size is presented.After larva is aging, luxuriantization is tied again in plant bottom and leaf sheath portion
Pupa.One larva all one's life edible 5~9 leaf of evil, it is a piece of withered white to be killed serious field presentation.Recently as hybrid paddy rice and of short stem
The popularization of kind and the change of cropping system, habitat and Feeding Condition are all preferable, thus rice leaf roller breed it is fast, into
Motility rate is high, and rice hazard is on the rise.It is largely built agent that medication is prevented and treated in production, only suitably prevents and treats 1~2 instar larvae,
