Abstract:

The effect of solar energy self-control multi-function and multi-mode trap lamp trapping pest on Areca catechu L. was studied. A total of 255 924 pests in 8 orders, 26 families and 46 species in 240 days were trapped, among which the number and weight of Lepidoptera pests reached 64.33%. The number and weight of trap lamp increased from August to November, decreased from December to February, and increased after March. The change of trap number was consistent with the occurrence law of local pests, and the beneficial insects accounted for only 0.80% of total pests. The pest grade of Areca catechu L. in the control area of trap lamp was less than that of the non-trap lamp by 1-3 grades, and the occurrence level of insect pests was less than ++. The fruit setting rate in the control area of trap lamp was significantly higher than that in the area without trap lamp at the beginning of flowering and fruiting. The fruit falling rate was significantly reduced, which made the yield of trap lamp reach 10.96 kg per plant, 36.61% higher than that of the area without trap lamp. The results showed that the trap had a wide spectrum of insect traps and strong trapping effect. It could reduce the occurrence of insect pests, increase fruit setting rate and increase yield when it is used in A. catechu L. orchard.
