Pest and disease forecasting

Occurrence of pests is expected to moderate, moderate emphasis on the local place. Are: downy mildew, powdery mildew, etc., the occurrence of an area of 113,000 hectares. Emphasis is expected to moderate this year, locusts occur farmland, Altay,[link widoczny dla zalogowanych], Tacheng, Urumqi, Hami and other regional and local outbreaks, the new development zone and occasional Ⅸ continue to increase, the occurrence of an area of about 66.7 million hectares of locust occurred Island area of 10 million hectares. Rodent occurrence of Agriculture is expected to moderate, moderate emphasis on the local occurrence, the occurrence of an area of 533,000 hectares. (XCY) 2006,[link widoczny dla zalogowanych], Zhejiang Cereals, Oils and major crop pests and diseases Forecast eyes pests and diseases under the conditions of 2005, the current base of the provincial meteorological pest white residue off of gas this year, trend forecasting and crop planting situation in our province, attending Pharmacy degree of resistance , combined with years of major pests Succession Law, the comprehensive analysis and forecast in 2006 for the emphasis on grain and oil crop pests occur, and types of pests and diseases increased. Wheat diseases and pests which occur secondary; Sclerotinia emphasis to place towels, etc.; migratory pest of rice leaf roller, and planthoppers, generation of single cropping of rice stem borer and sheath blight for the big happen; Stripe Disease of the further expansion of the occurrence and will continue to increase; black-streaked dwarf disease occurred Fan Si will be expanded. Wheat diseases and pests is expected to occur in 2006 an area of about 20 million hectares of oilseed rape pests is 23 million hectares,[link widoczny dla zalogowanych], to 633-667 million hectares of rice diseases and insect pests. (ZP) foreign magazines Abstract Anthranilicdiamides: action sites of a class of unique new pesticides. Over the years, insecticides single site. Xi is easy to produce drug resistance. A new insecticide anthranilicdiamides been developed. It acts on the ryanodine receptor, the role of the unique sites, Anthranilicdiamidespotently stimulate this receptor in the endoplasmic reticulum release of Ca \and found that similar to the original receptor sensitivity. In cockroaches ligand binding studies were labeled with isotopes showed ryuanodine and anthranilicdiamides separation. on mammalian cells in Ca \selectivity of the mammalian body is more than 500 times. Therefore, anthranilicdiamides pest management not only the importance of bamboo, but also a new type of Ca signals of pharmacological tools.

Spinosad Resistance of the beet armyworm channeling in experimental conditions, the study of beet armyworm resistance to spinosad cable and biological mechanisms of interaction, the results show that the fields and the beet armyworm collected from 5 generations in laboratory culture of spinosad resistance is sensitive to population 354.4 times. Spinosad cable and fenvalerate, phoxim, methomyl, avermectin rhizomorph and no cross-resistance to cyfluthrin. Mixture of several populations of sensitive and resistant populations of the contrast test showed that: PBO mixture of spinosad resistant populations better control effect. Microsomal -0 resistant strains of a demethylase (microsomal-O-demethylase) and glutathione transferase activity of a (glutathioneS-transferase) activity is sensitive to population 5.2,1.0 times. The results show that the microsomal 101 demethylase (microsomal-O-demethylase) may be more bactericidal against beet armyworm resistance to the main site index.

Corn rootworm on AIDS reagent and methyl parathion resistance stability in the absence of selection pressure,[link widoczny dla zalogowanych], the WEN asked Wada laboratory culture collection of corn rootworm Ai reagents and methyl parathion resistance stability, The results showed that: Laboratory culture of the populations Wada asked to collect two kinds of significant resistance to insecticides, methyl parathion LD,. Sensitive groups, respectively 19 times and 13 times, respectively, on l Ai reagent and 125 times less than 204 times. Fields and there is resistance to that population of the two kinds of corn rootworm resistance to insecticides in the absence of selection pressure characteristics can be inherited stably.
