Prevention and control of sunflower peach oysters from the living habits of sunflower, today Xiao Bian will share with you how to prevent sunflower peach pods.
First, living habits
The north is 2-3 generations old and 4-5 generations in the south. In the early stage, it mainly damages fruit trees or sorghum, corn and hemp crops. The second-generation larvae in the north and the third-generation larvae in the south endanger sunflowers. Adults live in a nocturnal manner. Hi lay eggs on the cutting edge of the sunflower plate or on the inner wall of the filaments and tubular flowers. The newly hatched larvae feed on the seeds and feed on the seed kernels. After growing up, they walk through the flower disk and many insect paths appear. In the rainy season, the disk is perishable, and the larvae mature on the disk or stalk after aging, and some larvae survive the winter.
Second, control methods
(1) Use hard, thick and smooth insect-resistant varieties of fruit shells.
(2) Pay attention to the treatment of overwintering hosts, eliminate overwintering larvae, and reduce overwintering pests.
(3) Use black light, high pressure mercury light, etc. to seduce adult insects.
(4) In the adult spawning period, spray 50% or 50% phoxim or 1000-1500 times liquid to control adult and newly hatched larvae.
The above is a method of preventing and controlling sunflower peach aphid. I hope I can help you.
