Abstract

The invention discloses a phthorimaea operculella zell attractant comprising the following components in parts by volume: 8-10 parts of alcohol compound, 0.5-1.5 parts of ester compound, 2-3 parts of aldehyde compound, 1-3 parts of terpene compound and 0.1-0.5 part of other compound, wherein the alcohol compound is any one of 1,8-eucalyptol and palustrol; the ester compound is any one of methyl jasmonate, anti-4, cis-7-C13 diene acetate and anti-4, cis-7, 10-C13 triene acetate; the aldehyde compound is any one of heptaldehyde, octyl aldehyde and nonaldehyde; the terpene compound is any one of limonene, phellandrene, terpinene, caryophyllene, pinene, elemene, ocimene, germacrene, farnesene and isolongifolene; and the other compound is any one of nicotine, solanone, norsolandione and para-cymene. The attractant is environment-friendly, does not injure natural enemies of pests and has remarkable attracting effect on phthorimaea operculella zell adults.

Description

technical field [0001] The invention relates to a potato tuber moth attractant and belongs to the technical field of pest control. Background technique [0002] Potato tuber moth (Phthorimaea operculella Zeller) is an important pest on tobacco and potato, especially on potato tubers during storage. [0003] Potato tuber moth is a borer pest. When it does damage in the field, the adults lay their eggs on the plants and in the gaps in the soil. After hatching, the larvae drill into the leaves of the plants to do damage. When damaging potato tubers during storage, adults often lay their eggs at tuber wounds or in bud crevices, and then newly hatched larvae drill into tubers to feed, causing tubers to rot, shrivel, and lose their use value. [0004] The odor produced by potato tubers has a strong attractant effect on the females of the potato tuber moth. Therefore, an efficient attractant for the females of the potato tuber moth can be developed by using the odor produced by th...
