The jujube pink scale has three generations a year, overwintering with nymphs in the bark, starting its activity in April, laying eggs in early May, and the egg period is 9-10 days. The peak period of nymphs of each generation is early June, mid-July and mid-September. A large number of overwintering began in early October.

This insect mainly harms branches and leaves with adults and nymphs. The damaged leaves were withered and yellow, and the jujube fruit wilted, resulting in the weakening of the tree potential and the decrease of yield.

What are the main measures to control jujube pink scale?

(1) scraping trees to eliminate overwintering nymphs.

(2) during the occurrence of the first generation nymphs, spray control can be carried out by using 1 Muthamel 2 degree stone sulfur mixture, pine ester mixture 25 Mel 30 times, 25% quinathion EC 1000 Mel 2000 times.
