Abstract

The invention discloses a food attractant for melon flies, which consists of the following components in weight percentage: 1 to 10 percent of a melon aroma substance, 10 to 25 percent of a solvent, 60 to 80 percent of a nutritional agent, and 1 to 10 percent of a preservative. The melon aroma substance can be a volatile aroma substance extracted from melons or other substances which also have melon aroma. The attractant has the advantages that the attractant has extremely strong attracting effect on adult female and male melon fruit flies (melon flies, pumpkin fruit flies), ensures that the attracted female and male proportion satisfies the natural population sex ratio of the melon fruit flies in vegetable gardens, can remarkably reduce the harm of egg laying of female fruit flies, achieve the aim of effectively controlling the melon flies and the pumpkin fruit flies, and is applicable to the nuisanceless or green good production of melon vegetables.

Description

technical field [0001] The invention relates to an insect attractant, in particular to a food attractant for fruit flies. Background technique [0002] There are two main fruit flies that harm melons: Bactrocera curbitae and Bactrocera tau. Both Melon Bacteria and Pumpkin Bacteria belong to Diptera, Tephritidae Tephritidae, and are important pests of melon vegetables and melons. Many countries and regions in the world have listed these two pests as important quarantine objects. Melon fly and pumpkin fruit fly are widely distributed in more than 30 countries and regions in subtropical regions, and are mostly distributed in Jiangsu, Fujian, Hainan, Guangdong, Guangxi, Guizhou, Yunnan, Sichuan, Hunan, Taiwan and other places in China. [0003] Bactrocera melon and Bactrocera squash have similar living habits and hosts, and the two pests often cause overlapping damage in the field. Its host range is wide, and there are more than 100 kinds of hosts that can be harmful. It mainl...
