Study On The Insect Diversity And Trapping Effect Of Different Coloured Traps On Insects

With the strengthen of environment protect consciousness, non-harmful produce had become basic need in international farm produce trade.It was pivotal to reduce pesticide hangover in non-harmful vegetable and fruit produce ,and abstain or reduce to the best of fone's abilities using pesticide.Therefore,it is very important that non-harmful plant diseases and insect pests comprehensive treatment in agrobiology.The design thought of this research embarked from insect pests non-harmful prevention and cure ,by using two kinds of traps: seven kinds of coloured cards and five kinds of coloured basin captured insects in field.With the knowledge and technique of ecology, taxonomy and statistics etc ,It analyzed the insect communities ,The results showed the dynamic of insect communities structure different coloured traps capturing.and analyzed phototaxis for domiant insects,study on the influence of sticky coloured cards on capturing insect in greenhouse. So,we can provide some reference for pests physics prevention and cure with insects phototaxis. Mostly research result is as follows:1.In tomato greenhouse:seven kinds of coloured cards captured 12 species of insects aggregately that belonged to 5 order and 9 family.As the whole , insect communities diversity is not hight , insect communities structure has biggish difference among different coloured cards. The dominant concentrator index of Homoptera and Diptera are higher than others.The dominant insects are Trialeurodes vaporariorum that belonged to Homoptera,which occupied 56.19%,and Liriomyza stativae Blanchard that belonged to Diptera, which occupied 38.78%. Significantly more Liriomyza stativae Blanchard and Trialeurodes vaporariorum were caught in yellow versus the others, green take second place .2. In open field, seven kinds of coloured cards captured 77535 heads that belonged to 8 order 27 family. As the whole , insect communities diversity is better, insect communities structure has biggish difference among different coloured cards. The dominant concentrator index of Homoptera ,Coleoptera and Thysanoptera is higher than others. Aphididae, Aleyrodidae, Cicadellidae, Delphacidae,Psyllidae, Chrysomelidae, Thripidae were main groups. The result showed significantly more Aphididae, Aleyrodidae, Cicadellidae, Delphacidae,Psyllidae were caught in yellow versus the other coloured cards, significantly more Chrysomelidae in yellow,and significantly more Thripidae in blue versus the other coloured.3.The effluence of different direction, height , size , shape on the capture efficiency of colored cards in greenhouse were also studied . The result showed that the best result can be achieved by placing them in east to west direction, vertically 15㎝ from the leaves of the plants, cylinder, and the size of card was irrelative to the trapping efficiency of Liriomyza stativae Blanchard and Trialeurodes vaporariorum.4. Five kinds of coloured basin captured 28 species of 3062 heads insects that belonged to 6 order and 21 family. Lepidoptera is most ,which family and species number were 9 and 12 ,occupied 42.86% of the whole. The number of individuality is most in Thysanoptera,which was 1158 heads and occupied 37.82%. insect communities structure has biggish difference among different coloured cards. Parnara guttata(Bremeret Grey), Frankliniella intonsa(Trybom), flies,bees were main groups.Blue basin caught the greatest Parnara guttata(Bremeret Grey). Significantly more Frankliniella intonsa(Trybom) were caught in blue than others.The blue basin caught greatest flies. Significantly more bees were caught in yellow and pink than red,blue and green.5. The result showed that different coloured sex pheromone basin influenced capturing Lithocolletis ringoniella Mats, Significantly more Lithocolletis ringoniella Mats were caught in green than others.It is not significant difference among different coloured sex pheromone basins on capturing Grapholitha inopinata Heinrich.
