Abstract

The invention relates to a prevention and control method for grape mealybugs. The prevention and control method comprises the following steps: firstly, ecological management: (1) paying attention to the use of phosphate fertilizers to strengthen the adverse resistance, and (2) applying Difulai and HYT(High Yield Technology) microorganism fertilizers to improve the soil texture and strengthen the soil fertility; secondly, agricultural prevention and control; thirdly, biological control; fourthly, biological prevention and control; fifthly, physical prevention and control; and sixthly, chemical prevention and control: (1) spraying a solution formed by diluting 25 g / l deltamethrin missible oil by 2000-2500 times for prevention when the mealybugs live through the winter, or using phoxim and pirimicarb around the soil so as to kill hibernating eggs, and (2) spraying a solution formed by diluting 25 g / l deltamethrin missible oil by 2000-2500 times for preventing and controlling the mealybugs living through the winter in the hatching period of each generation of larvae, so that the effect is better after a spreader is added in the medicament due to a layer of wax powder on the surface of each insect body. Moreover, the method can effectively prevent the grape mealybugs, and performs comprehensive prevention and control by adopting the measures such as agricultural prevention and control and physical prevention and control, so that the average incident rate of the grape mealybugs is reduced, the yield is increased, the rice level is obviously improved, and a good economic benefit is achieved.

Description

technical field [0001] The invention relates to a control method of grape mealybug, which belongs to the technical field of plant protection. Background technique [0002] Grape mealybugs mainly cause damage by adults and nymphs sucking juice under the skin of old vines and on the fine roots near the ground, forming large and small mound-like protrusions on the damaged parts. [0003] feature description [0004] The female adult of grape mealybug is 4.5-4.8mm long and 2.5-2.8mm wide, oval, lavender, covered with white wax powder, and has 8 antennae. Male adult, body length 1-1.2 mm, grayish yellow, transparent wings, purple luster in sunlight, 10-segmented antennae. There are 2 spines at the end of each tibia, and 1 pair of long needle-like setae at the end of the abdomen. Eggs are 0.32 mm long, 0.17 mm wide, oval, and pale yellow. The newly hatched nymphs are light yellow, with a body length of 0.5 mm and 6-segmented antennae with many bristles on them. There are 17 p...
