Pest Type: Currant and Gooseberry Pest
Row: Diptera – Diptera
Family: Gall midges – Cecidomyiidae
It is found throughout the country. Damages black currants.
The adult is 1.6-1.7 mm long, the abdomen is yellow-orange, and at the end of the abdomen there is a long pointed ovipositor; wings are glassy, covered with thin hairs. Egg 0.2-0.3 mm long, oblong, spindle-shaped. Larva – 2-3 mm, orange-black.
Larvae overwinter in cocoons in the soil. During the budding period, the currants pupate. At the beginning of the budding, adults emerge. Females lay eggs in blackcurrant buds. Larvae regenerate after 3-4 days, feed on the contents of the bud. Due to damage, the buds grow unnaturally, acquire orange-black colors and die. After feeding, which lasts 14-20 days, the larvae pass into the soil, forming a cocoon, remain in it until the spring of next year. One
generation develops per year.
The protective measures are the same as for the current gall midge. However, if the damage is exceeded by a threshold, only one spray with insecticides should be carried out during the period of bud swelling.
