Embodiment 1

[0034] A laboratory study of a series of plant volatiles as food attractants for the potato tuber moth using a Y-type insect olfactometer. Potato tuber moths are reared on potatoes and allowed to pupate in fine sand beneath the potatoes, after which pupae are collected and sorted by sex. 10 males and 10 females were placed in 50ml vials so that mating could occur after eclosion.

[0035] Bioassays were performed in a controlled environment at 25°C. A glass Y-shaped insect olfactometer (inner diameter 50 mm; stem length 150 mm; arm length 200 mm; inner angle 45°) was placed in a dark observation room. The surface of the observation chamber is covered with black cotton cloth. In order to be able to observe the movement of moths with minimum brightness, two red light-emitting diodes are placed on the upper wall of the observation chamber to provide uniform long-wavelength illumination. Two 50 mL glass bottles were placed outside the cages. Inlet air to each chamber was provid...

Abstract

The invention provides a food attractant for potato tuber moth and its application. The active ingredient of the attractant is methyl phenylacetate and / or ethyl phenylacetate, and may optionally contain co-attractants (such as potato tuber moth pheromone, etc.). The invention also provides a controlled release system of the potato tuber moth food attractant. The potato tuber moth food attractant and its controlled-release system of the invention can realize the population monitoring and comprehensive control of the potato tuber moth, and show extremely strong trapping activity in the field. The food attractant has low cost and high efficiency, and has great promotion value.

Description

technical field [0001] The invention belongs to the field of pest trapping drugs, in particular, relates to a potato tuber moth food attractant and its application. Background technique [0002] As an important source of food, potatoes play a pivotal role in agricultural production. Potato crops grow rapidly, produce large yields per acre, and can grow on soils unsuitable for cereal crops such as rice, wheat, and corn. [0003] Potatoes are susceptible to certain pests that limit effective potato production. The potato tuber moth (Phthorimaea operculella) is a major pest in potato production. It is both a storage pest and a field pest of potatoes. Seasonally, adults lay eggs on top of plants as they emerge, and on potato tubers when they are exposed on or close to the soil surface. The larvae continually bore into potato leaves and stems and infest tubers in the soil. The potato tuber moth can remain in the soil and reproduce for several generations. [0004] Insectici...
