Tea Insect Management
Tea mosquito bug

Both nymphs and adults of the mosquito bug prefer to feed on young plant tissue of leaves, tender stems, shoots, petioles and buds by piercing and sucking the plant sap with their proboscis. They are thereby injecting toxic saliva into the plant tissue causing it to break down into papery, pale brown necrotic patches. Feeding on the leaf results in water-soaked spot, which is at first circular and pale green turning dark
brown after a few hours. When the petiole and the mid rib are attacked they cause the curling of the leaf and it becomes distorted, blackens and finally dies. Feeding on the green shoot and its tip may result in the death of the shoot. In severe cases, the whole of the tea bush is blackened as if scorched by fire and there is virtually a total loss of crop.

1、Biological control: Spiders and praying mantis have been seen to catch and eat mosquito bugs but their influence on the pest population is not significant.

2、Cultural control: Monitoring the infestation level in the field, black plucking, weed control and removal of stalks containing tea mosquito eggs. Weeds serve as alternate hosts for many tea pests. The heavily shaded and moist areas will be damaged more by tea mosquito bug, therefore regulation of shade is important.

3、Insect application: Endosulfan, quinalphos (or mix with dichlorvos), chlorpyrifos,  fenthion. Minimum number of days between spraying and plucking is not less than 5 days to avoid taint. Spraying is done early in the morning and late afternoon when they are active. Spraying should be done after removing the infested leaves from the table by skiffing or by black plucking.
