Abstract

Infestation pattern of Carposina niponensis in plantations of Ziziphus jujuba and its control.

Abstract

Infestation of Ziziphus jujuba [Z. sativa] by Carposina niponensis was studied in the field in Shanxi, China, in 1983-85. The rate of infestation normally reached 60-70%. The generations overlapped, with adults of the overwintering generation emerging in mid-May, the eggs of the 1st generation being laid in early August and 2nd-generation larvae emerging from fallen fruit. Application of 50% fenitrothion, 50% parathion, 20% fenvalerate or 20% deltamethrin at the oviposition peak of the 1st and 2nd generations and removal of fallen fruit were effective means of control.
