Medicinal Herb Cultivation 0 views
The red gall midge of goji belongs to the family Cecidomyiidae. The larvae damage the ovary inside the young buds, forming deformed flower buds that cannot bloom. The red gall midge of goji produces about 6 generations a year, overwintering as mature larvae in the soil, pupating in the following spring; adults appear in mid-April when goji buds, and May is the peak period, with eggs laid inside the tops of young buds. The larvae bore into and feed on the ovary, and the infested buds become deformed. Because they cannot bloom, they drop off. In late September, the mature larvae enter the soil to overwinter. The control method is to spray a 50% 1605 emulsifiable concentrate at 1000 times dilution in mid-April,

The control method is to spray a 50% 1605 emulsifiable concentrate at 1000 times dilution in mid-April, spray a 200 times dilution for ground closure, then irrigate. For larvae inside young buds, systemic insecticides such as a 40% omethoate 800 times dilution should be sprayed.

In addition, there are also the goji leaf beetle, the goji fruit-boring moth, the goji flea beetle, the goji black mirid bug, the goji leaf-roller moth, the Changchun weevil and the Indian meal moth, etc.
