Attractant for Drosodhila suzukii Matsumura and application method thereof

Abstract

The invention discloses an attractant for Drosodhila suzukii Matsumura and an application method thereof. The attractant is prepared by mixing glutamic acid, cane sugar, table salt, an odor attractantand a color attractant according to a weight ratio of (80-100): 20: (20-25): (20-25): (5-6). The attractant starts to exert an attracting effect when the concentration of an attractant aqueous solution is 3 g / L or above, has stronger attractive force with higher concentration, and achieves an effective distance of 5 to 30 meters. According to the invention, the Drosodhila suzukii Matsumura has acharacteristic of needing to supplement a great amount of nutrients in a period of time during the process of development; the tendency of the Drosodhila suzukii Matsumura to some colors and smells iscomprehensively utilized; the attractant is used by cooperating with pesticides like avermectin, spinosad and highly-efficient cypermethrin; thus, trap-killing and toxic-killing effects are greatly improved, and the number of a Drosodhila suzukii Matsumura population can be greatly reduced.

Description

Technical field: [0001] The invention relates to the technical field of pest control, in particular to a spotted wing Drosophila attractant and an application method thereof. Background technique [0002] Spot-winged fruit fly (Drosodhila suzukii Matsumura) reproduces fast, has a wide range, a large number, and harms many kinds of fruits. The female ovipositor is hard and sawtooth-shaped, and can lay eggs directly in mature or soon-to-mature fruits, resulting in a serious decline in fruit commodity production, increasing the operating costs of orchards, and greatly eroding the economic benefits of fruit farmers. The development of the fruit industry has brought serious losses. [0003] In order to prevent the harm of fruit flies, agricultural science and technology departments and scientific and technological personnel at all levels research and promote the comprehensive control technology of fruit flies. At present, the methods for preventing and controlling fruit flies m...

Problems solved by technology

Since the current sex attractant can only attract males, it is difficult to have an effect on the females that have the greatest impact on production, and the fruit fly has a strong reproductive ability, so the control effect is poor, and it can only be used as a means of forecasting and auxiliary control.

In order to fundamentally prevent and control Drosophila spotted wing, we can only make comprehensive use of sexual lures, natural enemies, chemical agents, color lures and food traps.
