目的研究人帐诱法和CO2灯诱法对北湾地区蚊、蚋种群昼夜活动的变化规律。方法选取3种不同生境同时采用人帐诱法和CO2灯诱法进行昼夜数量动态的调查。结果 2种方法对于危害种类及组成调查结果一致,在3种生境中班布蚋的危害均大于蚊虫,刺扰伊蚊为当地的优势蚊虫,组成占到95%以上,里海伊蚊和米赛按蚊数量很少;对于种群昼夜活动节律,刺扰伊蚊2种方法结果一致,都具有晨峰和昏峰,昏峰明显,数量多,晨峰数量较少,班布蚋的活动曲线较为复杂,不同生境变化较大,但一般具有4个高峰,两种方法调查结果差异较大。结论人帐诱和CO2灯诱都可作为蚊虫种群数量及活动节律的调查方法,但对于蚋种群CO2灯诱法是否能作为数量及活动节律的调查方法,还需做进一步的研究。 Objective To study the changes of circadian and circadian activities of mosquito and populus euphratica populations in Beibu Gulf by the methods of human-induced trap and CO2-light trap. Methods Three different habitats were selected to investigate the diurnal dynamics of the population by using the method of human-led accounting and CO2-light induction. Results The results of the two methods were consistent with the results of the investigation on the types and composition of the hazards. The damage of Bambu in the three habitats was greater than that of mosquitoes, and the dominant mosquito was Aedes albopictus, accounting for more than 95% of the total. The number of Anopheles mosquitoes was very small. The results showed that both the circadian rhythms of circadian rhythms and Aedes albopictus were consistent. Both of them had the morning peak and the fainter peak, the faint peaks were obvious, the number was large, the number of the morning peaks was small, Complex, different habitats vary greatly, but generally has four peaks, the two methods vary widely. Conclusions Both human-led accounting and CO2-light inducement can be used as investigation methods for population and activity rhythm of mosquitoes. However, further studies are needed to investigate whether the CO2 light induction method can be used as a method to investigate the quantity and activity rhythm.
