自然状态下大实蝇成虫羽化和柑橘实蝇类害虫田间虫量监测

本实验对川东北地区自然状态下柑橘大实蝇成虫羽化监测,诱蝇球诱集方式监测大实蝇、小实蝇和南亚果实蝇在柑橘弃管园中田间虫量实验。掌握了川东北地区柑橘大实蝇成虫羽化始见日在5月10日,盛期在5月中下旬；田间成虫监测发现诱集盛期在6月中下旬,终见日在7月25日；测算了大实蝇羽化和田间成虫始盛期、高峰期、盛末期的期距分别是34、31、37天,为确定防治柑橘大实蝇最佳时期提供依据。在南充嘉陵区老石坎地区监测出主要是南亚果实蝇,橘小实蝇虫量较少。

Field insect quantity monitoring of adult larval fly emergence and citrus fly pests in natural state

The experiment was conducted to monitor the adult emergence of citrus fruit fly in the natural state in northeast Sichuan, and to monitor the insect population of citrus fruit fly, small fruit fly and South Asian fruit fly in the field of citrus abandoned pipe. It was found that the emergence of adult citrus fruit fly in northeast Sichuan began on May 10, and the peak period was in mid to late May. The adult insects in the field were observed in mid to late June, and the final date was July 25. The time interval between emergence and the beginning, peak and end of mature insects in the field was 34, 31 and 37 days, respectively, which provided the basis for determining the best time to control citrus fruit fly. In the Lao-Shikan area of Jialing district, Nanchong, the number of fruit flies was mainly South Asian, and the number of orange flies was relatively small.
