BIOECOLOGY OF CALIFORNIA SHIELD (QUADRASPIDIOTUS PERNICIOSUS COMST) IN UZBEKISTAN

Abstract

Dangerous coccids are widespread in Uzbekistan. Of these, the californian shield insect is a quarantine pest. It damages many plants. It damages apple, pear, plum, quince, peach, almonds, hawthorn, elm, poplar and others. Diapausing larvae of the first age overwinter, covered with a dark gray or black shield. In spring, it feeds intensely, molts and forms a shield similar to that of an adult female. After the second molt, adult females are formed. After mating, the female spawns larvae of strollers, which spreads along branches and leaves, and can also settle on fruits. It gives rise to the next generation.
Key words: Female, male, larva, phase, cycle, molting
