Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to an insecticide for controlling Plutella xylostella and a screening method thereof. Background technique [0002] The diamondback moth (Plutella xylostella Linnaeus) belongs to the family Lepidoptera. One of the worldwide migratory pests, mainly damages cruciferous plants. Cruciferous vegetables are easy to reproduce in large-scale planting areas, and the warm winter and dry climate with little rain are conducive to population development. The larvae mainly feed on the leaves, the first instar larvae only eat the mesophyll, and the larvae above the third instar eat the vegetable leaves into holes and notches, and in severe cases, the leaves become reticular. At the seedling stage, it often concentrates on the heart leaves, and the seedlings mainly damage the tender stems, young pods and grains. Plutella xylostella has a large overwintering base and low natural mortality, w...
