A Detailed Guide to the Harm Caused by the Jujube Leaf Beetle and Its Control Methods
The jujube leaf beetle belongs to the order Coleoptera, family Chrysomelidae. The larvae and adults of this insect damage jujube leaves and tender shoots. In outbreak years, the leaves are eaten bare, leaving only the bare fruiting branchlets, which greatly affects yield. The peak damage period for this insect is from mid-April to mid-May. Both larvae and adults damage jujube leaves, tender shoots, flower buds and flowers. Control methods: spraying mainly for flower protection is the primary approach. During the occurrence period of larvae and adults, spray 90% trichlorfon at 1500 times dilution or deltamethrin at 1.5 ten-thousand to 1.6 ten-thousand times dilution; generally the insecticidal effect is very good.
