Last Updated: 2024/11/22, Chinese wolfberry aphids, also known as green honey, honey, belong to the aphid family. Cluster tender shoots, buds, green fruits and other parts, absorb juice, damaged shoots curl, growth stagnation. In serious cases, the surfaces of leaves, flowers and fruits of Chinese wolfberry are all covered by aphid secretions, affecting photosynthesis, causing early defoliation, resulting in a great reduction in yield. Chinese wolfberry aphids occur for about 15 generations a year, overwintering with eggs in branch gaps and bud axils, hatching as dry mothers in late April of the following year, parthenogenetic birth, and winged aphids in the second and third generations, which propagate and expand in the field.

Chinese wolfberry aphids occur for about 15 generations a year, overwintering with eggs in the cracks and axils of buds, hatching in late April of the following year as dry mothers, parthenogenetic birth, winged aphids appear in the second and third generations, propagate and expand in the field, the aphid density is the highest from mid-May to mid-July, and the damage peak is in June. The insect population decreased slightly in the middle and last ten days of July, and the insect population density was the lowest in August and increased in September, causing damage to autumn shoots, producing sexual aphids in the first ten days of October, mating and spawning, peak spawning in the middle of October and the last ten days of November. During the damage period, the daily average temperature was between 18 ℃ and 28 May. the higher the temperature and the less rainfall, the faster the number of aphids increased.

At the initial stage of growth, 3% carbofuran diluted 2000 times liquid spray, 24% Wanling water agent 1000-1500 times liquid spray, 40% omethoate 1000 times liquid plus 5% rifampicin 5000 times liquid spray, the control effect can be achieved.
