Tea stem borer is a kind of borer pest that commonly occurs in southern China's tea gardens. Not only did it cause tea production reduction in the same year, but it also caused tree decline. According to surveys in Yangmaoyang Township in Yiyang, Hunan Province, the old tea plantations had almost worm-bumps in the plexus, and the damage rate of tea shoots with a diameter of 8 mm or more was 23.4%, and the rate of larvae was 10.3%. The victim’s death is often caused by the death of the victim’s branches. The masses often mistakenly believe that the tea tree has died naturally, and the production does not pay much attention to its control.
Tea cricket larvae hatched very irregular, lasting about 40 days, soon after drilling into the shoot shoots, unfavorable drug kill. Tea is a direct edible agricultural product and should not be used as medicine. According to the hazard characteristics of tea aphids, it is most economical, simple and effective to adopt the prevention and control method of timely cutting off pests. There are only 0.5 flower workers per acre, and the cutting effect is more than 95% at a time. It can effectively control the damage and protect the tree vigor.
The worm occurred in 1 generation in Yiyang, Hunan, and the field larvae hatched in late June. In the middle and late July, it was the hatching period. After hatching, the larvae enter the tea shoots from the young part of the tea shoots. After 4 to 5 days, the xylem is damaged and the leaves of the tea leaves begin to wilt. The larvae plucked down from the branches, first damaging the side branches, and then standing along the side branches into the main branches, until the base of the tea stems, tea stems with a diameter of 1 to 2 cm can also be strangled by it. Due to the damage of main stems, the transport of water and nutrients is difficult, and the above branches (including a large number of branches that have not been damaged) of the affected parts are all dead. As a result, the actual loss of the tea tree is several times greater than the damage. The longer the damage to the larvae, the greater the loss of the tea tree, so early measures to eliminate the larvae can significantly reduce losses.
Cutting pests at the right time is a simple and effective measure to control the insects. According to a systematic survey, the insect shoots sporadically occurred at the end of June, and the number of vermiform shoots increased sharply in the middle and late July. In early August, only a few new shoots appeared, and they entered a stable period in the middle of the month. Therefore, mid-August is the appropriate period for cutting tipping. At this time the advantages of cutting tip: 1 insect removal effect is good. One-off cutting tip, the pest removal rate of up to 95%, too early cutting, cutting more than a few times to control the insect pests, spend more; cut too late, tea tree loss aggravated. 2 provincial workers. In August, tea leaves were green and green, and the larvae appeared wilting, chlorotic, and then yellow, but they did not fall off and were clearly visible at a long distance. After October, the leaves of the damaged branches fell off, and they were easily confused with the light branches caused by diseases or mechanical damage. The accuracy of cutting off the shoots was greatly reduced, and the labor force increased by 2 to 3 times. 3 less loss of tea buds. According to the survey, in mid-August, only 5 tea buds were lost per tip, which had little effect on the yield. After one and a half months, it increased to 61, and 103 tea buds were lost after three and a half months, a 19-fold increase. 4 can protect the tree potential. In mid-August, the tip was cut, and only 1.02 grams of shoots were cut per shoot without damaging the tree vigor. After 1 and a half months, 23.6 grams of branches were cut and increased to 51 grams after 3 and a half months, an increase of 49 times. Almost equal to the weight of a main branch, severely weakened the tree vigor, affecting tea production in the coming year.
As long as it is timely and economically profitable, the cut-tip tea stem worms only have 0.5 flowers per acre, which can save more than 8% of tea losses, protect the tree vigor, and can benefit all year round, and can also reduce the number of application times during tea collection. It is beneficial to improve the tea garden ecological environment.
