How to control litchi fruit-boring pests? These methods are very effective
Litchi fruit-boring pests include the litchi tortricid (Cryptophlebia ombrodelta), the litchi small grey moth, the Yaowen moth and the litchi stem-end borer, among others.

Litchi fruit-boring pests include the litchi tortricid (Cryptophlebia ombrodelta), the litchi small grey moth, the Yaowen moth and the litchi stem-end borer, among others. Damage begins each year when litchi trees start to flower, and is most severe from late April to early June. The larvae first bite through the skin of the young fruit, then bore into the fruit and feed on the stone, causing heavy fruit drop, reducing yield and lowering fruit quality, with enormous damage. In addition, the larvae also feed on the young stems of litchi trees, greatly affecting the trees' vigour. Therefore, it can be said that litchi fruit-boring pests are the most important pests in litchi production. If they can be eliminated economically and effectively, higher yields and incomes from litchi orchards can be expected; otherwise it is just empty talk.
Because these pests have strong resistance to insecticides and bore into the stone to feed, conventional insecticides such as organophosphates (trichlorfon, dichlorvos), pyrethroids (fenpropathrin, cypermethrin), carbamates and some specific insecticides cannot achieve the expected control effect, and even some expensive imported insecticides are still not ideal. According to our large-scale trials, spraying with 7.5% Chongba emulsifiable concentrate at a 1:2000-4000 dilution gives a control effect of more than 98%. If quicklime milk made from 1-1.5 kg of quicklime is added to the spray solution, stirred thoroughly and then sprayed, the insecticidal effect is even better, and it can also ensure that there is no damage from fruit-boring pests for one month. This product also controls other litchi pests such as the litchi stink bug, the longan lanternfly and the white moth bug.
Debao brand 7.5% Chongba emulsifiable concentrate is one of the patented products produced exclusively by Deqing Xijiang Plant Protection Chemical Factory. The product is refined from a variety of plants and has systemic, contact and stomach-poison action. It is a highly effective, low-toxicity, economical and safe botanical insecticide, with good results against insecticide-resistant pests.
