[Method] With winter pupae of fall webworm as the test materials, genomic DNA of fall webworm were extracted by five different methods including CTAB method, SDS method, improved SDS method, kit method and different processing time. Six groups of different primers were used to amplify sequences of CO I and CO II and Cytb. [ Result~ Full DNA could be extracted by CTAB method, SDS method and improved SDS method, and the effort of low concentration SDS method was the best. Six groups of primers could amplify the corresponding fragment, and two groups of primers had the best effort for amplification of CO I . [ Conclusion] The study provides better methods for DNA extraction.展开更多

The control strategies and methods to it for the last two decades in China were briefly reviewed. Because the fall webworm has already adapted to the new habitat in China, some considerable control strategies should be developed. Based on the study of fall webworm in three typical ecological conditions and its special biological characteristic, relative different control strategies and methods were proposed for this invasive pest.展开更多

Meanwhile, the curve diagram of functional relationship between theoretical development duration and temperature is given. These data are important in mass\|rearing the wasp for biological control of the pest.展开更多
