CN102696596B - Insect sex attractant comprising butyl hydroxy anisole as synergist - Google Patents

Abstract

The invention relates to an insect sex attractant, in particular to a high-efficiency athetis lepigone sex attractant which comprises an active component A and a synergist B. The component A comprises cis 7-dodecene acetate and cis 9-tetradecene acetate which are at the ratio of 5:1 to 1:5. The synergist B is the butyl hydroxy anisole. Compared with the athetis lepigone attracting effect of the reported athetis lepigone sex attractant, the athetis lepigone attracting effect of the high-efficiency athetis lepigone sex attractant is improved by several times significantly.

Description

A kind of insect sex attractant that comprises the butylated hydroxy anisole synergist

Technical field

The present invention relates to a kind of insect sex attractant, be specifically related to a kind of insect sex attractant that comprises the butylated hydroxy anisole synergist.

Background technology

2 the committee noctuid [ Athetis lepigone(M schler, 1860)] be the de novo a kind of pest in China summer corn producing region.

According to the interrelated data record, domestic early than find 2 committee's noctuid harm summer corn seedlings in July, 2005 in the area, Shijiazhuang City, Hebei Province, bore the moth basal part of stem, it is dead to cause the withered heart of seedling to be wilted, or bites corn root broken, causes lodging, cause the serious disconnected ridge that is short of seedling, this belongs to reported first at home.It is reported, 2 committee noctuids were generally taken place in summer corn district, the middle and south, Hebei province in 2010,2011 in Hebei, province such as Henan, Shandong, Shanxi, Anhui, Jiangsu breaks out, area takes place reach more than 3,000 ten thousand mu, account for 20% of summer corn sowing area, the minority plot is reseeded or is ruined kind, is rare serious insect pest in the Maize Production in recent years.

It is reported that it is movable and lay eggs at hidden moist place that 2 committee noctuid adults are liked, larva is also liked the movable and damage to crops seedling at hidden moist place.In recent years, summer corn producing region, the Yellow River and Huai He River sea had realized generally that wheat mechanized harvest, summer corn pasted stubble sowing etc., and the harvested stalk of wheat directly is scattering into the field, for generation and the harm of 2 committee noctuids provides large tracts of land favourable suitable environment.

This insect colony is big, heavy to murrain.1 female worm can lay eggs 300 ~ 500, and what have around the one strain maize seedling of field reaches 20 larvas, and this worm mainly gnaws the corn young shoot, bores moth corn lobus cardiacus, destroys growing point, 1 strain production loss, 1 strain of causing harm.This insect is disguised strong, and low instar larvae is difficult to be found under wheat straw covers; In addition, this insect speed that causes harm is very fast, and it is big that high instar larvae appetite becomes, the beginning gluttony, but and clustering cause harm, can cause serious seedling death phenomenon at short notice, and general spray medicine or spread pesticide-clay mixture etc. and be difficult to pass the thick wheat straw insect that tags.

Insect sex pheromone is a kind of at adult and mating process, to vitro release can attract go mating before the different in nature insect of the same race, play the trace level chemical substance of communication effect.During with artificial synthetic sex pheromone or analog pest control, be commonly referred to the insect sex attractant, be called for short gyplure.Coming pest control with gyplure is a kind of control of insect new technology that development in recent years is got up, because of its have efficient, nontoxic, do not injure beneficial insect, advantage such as do not pollute, both at home and abroad this Study on Technology and application are all taken much count of, now the gyplure of existing hundreds of insects is used.Both at home and abroad two researchs of selecting committee's noctuid gyplure are only had a small amount of report, and made gyplure lure the moth poor effect, 20 of month to date induced moth number less thaies are needed badly and are a kind ofly selected committee noctuid gyplure efficiently to two.Do not report at present as the synergist of gyplure about butylated hydroxy anisole, the present inventor finds, adopts butylated hydroxy anisole to have good effect as the synergist of the suitable 7-dodecylene acetate of active component and suitable 9-tetradecene acetate.

Summary of the invention

The method that the objective of the invention is to overcome 2 committees of control noctuids is single, do not have or sporadicly report two select committee's noctuid gyplure poor effect, fail to form the present situation of main flow prophylactico-therapeutic measures, provide a kind of and select the gyplure of committee noctuid for two.

The objective of the invention is to be achieved through the following technical solutions:

The invention provides a kind of two and select committee's noctuid gyplure, it is characterized in that comprising following component:

The active component A of 91 ~ 97 weight %;

The synergist B of 3 ~ 9 weight %;

Described active component A is by forming along 7-dodecylene acetate with along 9-tetradecene acetate, and the weight ratio of the two is 5:1 ~ 1:5; Synergist B is butylated hydroxy anisole.

Preferably, gyplure of the present invention comprises the active component A of 95 weight %, the synergist of 5 weight %;

Preferably, the weight ratio along 7-dodecylene acetate and suitable 9-tetradecene acetate is 1:1 in the active component A.

Butylated hydroxy anisole is domestic and international widely used oil-soluble inhibitor, and is nontoxic in the valid density scope, but its oxidation resistance is stronger, heat-resisting and good stability.Generally mix use with other fat-soluble antioxidants, better effects if is used for the antioxidant of cosmetics, food etc. more.In the gyplure of having reported, do not see interpolation is arranged.

Except as otherwise noted, " % " in this specification all represents percentage by weight.

The invention has the beneficial effects as follows: provided by the invention two select committee's noctuid gyplure with reported two select committee's noctuid gyplure and compare, (that has abroad studied that two of report selects committee's noctuid gyplure lures the moth poor effect to lure the moth effect obviously to strengthen several times, 20 of month to date induced moth number less thaies, the effect of domestic report is more quite a lot of, but also 100 of less thaies of monthly average accumulative total induced moth number); 2 committee noctuids are important pests that China newly breaks out, and big with the conventional method difficulty of prevention and cure, the present invention has great economy, ecology and social effect.

Provided by the invention two select committee's noctuid gyplure has following advantage: artificial synthetic; Simple in structure; Using dosage is atomic; Free from environmental pollution; The height specificity; Do not produce resistance; Need not electricity consumption; Use simple, safety, economy, efficient, be convenient to promote.Compare with additive method, use 2 committees of method trapping of the present invention noctuid, can reduce labour intensity significantly, save the energy, improve the accuracy that 2 committee noctuids are observed and predicted technology.Provided by the invention two select committee's noctuid gyplure with reported two select committee's noctuid gyplure and compare, lure the moth effect obviously to strengthen several times; 2 committee noctuids are important pests that China newly breaks out, and big with the conventional method difficulty of prevention and cure, the present invention has great economy, ecology and social effect.

Embodiment

Experimental field: paste stubble sowing corn field of summer

Test period: 25 days-July 31 July in 2011

Test method is with embodiment 1.

Test is handled:

A: suitable 7-dodecylene acetate: along 9-tetradecene acetate=1:1, do not add butylated hydroxy anisole;

During following B, C, D, E handle as active component A: be 1:1 along 7-dodecylene acetate with along the weight ratio of 9-tetradecene acetate;

The active component A of B:97 weight % and the butylated hydroxy anisole of 3 weight %;

The active component A of C:95 weight % and the butylated hydroxy anisole of 5 weight %;

The active component A of D:93 weight % and the butylated hydroxy anisole of 7 weight %;
