Abstract
The present invention provides an attractant for melon trypetids, which is prepared from 200 to 10 volume portions of anisyiacetone l-2-butanone, 5 to 1 volume portions of ethyl butyrate and 1 volume portion of ethyl acetate according to the volume proportion. The present invention has preferred components that the anisylacetone is 50 to 10 volume portions, the ethyl butyrate is 1 volume portion and the ethyl acetate is 1 volume portion. Test show that the attractant for melon trypetids of the present invention has better attractive effect on melon trypetid imagoes than that of an attractant which has a single component such as anisylacetone, ethyl butyrate or ethyl acetate. The attractive number of the melon trypetid imagoes which are attracted by the attractant which has preferred components has 1.5 times higher than that of the anisyiacetone attractant which has a single component.
Description
Technical field
The invention belongs to a kind of non-harmful melon-fruit-like vegetable protectant, relate to and a kind of melon trypetid (Bactrocera cucurbitaeCoquillett) adult is had the attractant of attracting action.
Background technology
Melon trypetid (Bactrocera cucurbitae Coguillett) claims melon little trypetid again, and popular name pin honeybee, melon maggot, golden fly etc. are subordinate to diptera, Tephritidae, are polyphagous pest-insect, are distributed widely in Southeast Asian countries and regions.About 125 kinds of cultivation fruits and vegetables and wild plants such as melon trypetid harm balsam pear, pumpkin, muskmelon, tomato, capsicum, lemon, tangerine, mango.Female worm lays eggs in the tender melon and fruit of children, and the larval feeding melon and fruit causes serious rotten, shedding.
The melon trypetid all has adult to occur taking place many generations (general 3～5 generations in the South China) in annual year the whole year, and the generation overlap phenomenon is obvious.The first generation is led the evil cucumber in 4～May; The second generation is led evil cucumber and balsam pear in 6～July; The third generation is in 8～September, and the master hurts melon and sponge gourd bitterly.Heavier with second and third on behalf of evil.Survive the winter in soil with pupa.Sprouting wings April in next year adult, comes into play.
Adult activity on daytime, it is fast to circle in the air, and contains most with the morning 8～10 o'clock and afternoon 3～5 an o'clock activity especially.Rainy day and have a rest often statvolt in blade back, weeds clump or under the melon canopy, night inertia.Adult is thrust melon skin with oopod and lays eggs, and can lay eggs several to tens 1 time.Newly hatched larvae earlier from oviporous orifice to the melon centre level development of causing harm in the heart, cause harm to the lower end then, expand to the upper end at last.The melon body but mature larva headtotail bullet jumps out, it is far away that 8～14cm can be ejected 1 time in the plane, generally reaches 10cm, falls within ground and promptly pierce in the soil and pupate.3～4 days pupa time.Larval phase, can reach 12～15 days.
The trapping method is a method of killing the melon trypetid commonly used in the world at present.Anisylacetone (4-(right-the acetate phenyl)-2-butanone) (C
12H
20O
2) be the attractant for melon-trypetid of using always.Because the volatility of anisylacetone is not good enough, so show in application, uses anisylacetone not good enough as the attractant for melon-trypetid effect separately.And ethyl butyrate and ethyl acetate all are the essence with fruit aroma, use separately almost can not produce attracting action to the melon trypetid.
Summary of the invention
The objective of the invention is to propose a kind of to the better attractant of melon trypetid adult attractant effect.This attractant is with anisylacetone (C

Ethyl butyrate (C

12O
2) 5～1 parts by volume
Ethyl acetate (C

2) 1 parts by volume.
The preferred ingredients proportioning is:
Anisylacetone (C

2) 50～10 parts by volume
Ethyl butyrate (C

2) 1 parts by volume
Ethyl acetate (C

2) 1 parts by volume.
The results showed, attractant for melon-trypetid of the present invention obviously is better than anisylacetone, ethyl butyrate or the ethyl acetate attractant for melon-trypetid of separate constituent to melon trypetid adult attractant effect, and the attractant for melon-trypetid of its preferred component reaches as high as 1.5 times of anisylacetone attractant for melon-trypetid of separate constituent to the number of luring of melon trypetid adult.
Anisylacetone, ethyl butyrate are as shown in table 1 to the test data of the attractant effect of melon trypetid with the different proportionings of ethyl acetate.

Attractant disclosed by the invention can be used for field trapping melon trypetid adult according to conventional method.
Embodiment
The following example is further to explanation of the present invention, should not be used as limitation of the present invention.
Embodiment
Anisylacetone, ethyl butyrate are mixed formation A, B, four attractant experimental group of C, D and E, F, four control groups of G, H with ethyl acetate according to the parts by volume ratio of table 1, every group with degreasing cotton absorption 2ml anisylacetone, ethyl butyrate and ethyl acetate mixture (control group then is anisylacetone, ethyl butyrate and ethyl acetate 1: 1 mixture, ethyl butyrate or ethyl acetate) then, place small-sized closely knit bag, adsorb 0.2ml dichlorvos (as insecticide with degreasing cotton again, can kill the melon trypetid adult of being lured) in the same closely knit bag of packing into, seal sack.With small pinhead 6 apertures of thorn on closely knit bag, attractant and dichlorvos can be evaporated.The closely knit bag that attractant is housed is placed the porose mineral water bottle of body, be hung in kind of the melon ground of the booth that balsam pear is arranged.Experiment back the 1st and the 3rd day is checked respectively by attractant and is lured the melon trypetid quantity that enters in the mineral water bottle.3 repetitions are established in each processing.With the degreasing cotton that only adsorbs 0.2ml dichlorvos in contrast.
As can be seen from Table 1, the mixture of anisylacetone, ethyl butyrate and ethyl acetate can be lured melon trypetid adult, and lure the quantity of melon trypetid all to be higher than the quantity that control group is lured the melon trypetid, particularly when the proportioning of anisylacetone, ethyl butyrate and ethyl acetate is 50: 1: 1 or 10: 1: 1, the melon trypetid quantity that its quantity of luring the melon trypetid is lured apparently higher than independent use anisylacetone, ethyl butyrate and ethyl acetate 1: 1 mixture, ethyl butyrate or ethyl acetate control group.The degreasing cotton that only adsorbs 0.2ml dichlorvos does not have attracting action to the melon trypetid.
