A mixed finite element method is used to treat a model of Trichogramma Pyralis ecological problem with transport terms.

The characteristics of occurrence and reason for rice stem borer in Fujian province;

Investigation on the population compose of the rice stem borer and parasitic natural enemy in the eggs of Tryporyza incertulas;

The resistance to striped stem borer(SSB)、 yellow stem borer(YSB) and purplish stem borer(PSB) were studied by using Bt transgenic rice Shanyou63/Bt, Shanyou63 as the control varieties.

The variation of mtDNA COII sequences in 9 geo-populations of rice stem borer,Sesamia inferens;

Effects of Transgenic Rice Harboring cry1Ac and CpTI Genes on Survival of Chilo suppressalis and Sesamia inferens and Field Composition of Rice Stemborers;

Effects of Sublethal Dose of Fipronil on Detoxifying Enzymes in the Larvae of Chilo suppressalis and Sesamia inferens;

Control of Sugarcane Borers Using Regent 0.3G;

The paper introduces the morphological characteristic,living habit and harm feature of sugarcane borers(Chilo sacchariphagus Bojer,Sesamia inferens(Walker),Chilo infuscatellus Snellen) in Guizhou and puts forward the control techniques including the agronomic,biological and pesticide control ways in sugarcane production.

Combination of sex pheromone and frequency-vibration trapping night light gave the best effect in controlling borers, longhorn beetle (Dorysthenes granulosus (Thomson)), chafer (Alissonotum impressicolle Arrow) with optimum sugar content and theoretic cane yield, followed by night light trapping, then sex pheromone, and the last, Carbofuran whic.
