Researchs On Artificial Feeding Of Agrilus Mali Matsumura(Coleoptera:Buprestidae) In Stands Of Malus Sieversii In Xinjiang

Xinjiang wild apple forest is located in the Yili valley area,the construction of tree species is Xinjiang wild apple forest.A.mali mainly harm rosewood fruit trees,the insects have spread in Xinjiang wild fruit trees,a large of harm Xinjiang wild apple,pear,peach,cherry,sand fruit,bonus,begonia and so on.Due to the understanding of A.mali not enough to lead to the lack of effective prevention and control,and carry out prevention and control technology and other aspects of the study,but also need adequate A.mali.Therefore,the main results obtained in this study are as follows:(1)The results showed that the average feeding leaf area was 251 mm~2,the male larvae continued for 11 days,the average leaf area was 118 mm~2,and the dry treated group averaged survived 38.6h,the survival of the wet group 84.9h,feeding group survival 218.4h,the larvae fed the peak of the adults was 16 days.(2)The average body weight of early stage,middle stage and late stage of adult was2.13mg,1.82mg,1.57mg and 1.51mg respectively,and the body weight decreased by 29.11%at the end of pupal stage.Therefore,the energy consumption in pupal stage occurred mainly in the middle stage of pupa-Late pupa.(3)The results showed that at room temperature,the adult feathering period lasted about 13 days,the time of preservation of branches at low temperature was about 30 days,and the eclosion rate was lower than 60 days.In the feeding,eclosion rate of 80%;remove the insect spot bark is conducive to improve the eclosion rate and shorten the eclosion period.(4)Screening out one kind of ideal artificial feeding formula,the larvae can live for up to 55 days,and most of the larvae can bite into the inside of the feed to maintain the vitality,but the vitality of the larvae can be maintained.Feather rate is low.
