摘要
室内药敏试验0.1%—0.5%保蚕宁2号对柞蚕链球菌有抑制作用,四龄盛食期添食0.13%保蚕宁2号对柞蚕再感染空胴病有防治作用,旦效果显著。小区试验经添食药物的空胴病发病率下降69.5%,死笼茧率平均下降38.25%,结茧率平均提高50.25%。农村多点试验治愈率达63%,发病率下降67.3%,结茧率提高52.11%。保蚕宁2号药源充足,价格适宜,可在柞蚕生产区普遍推广应用。
Results from chemical sensitivity
experiment in lab indicated that“Baocanning 2”atconcentration of 0.1 0.5%could inhibit the
growth of Streptococcus pernyi in oak silk-worm.Administration of 0.13%“Baocanning 2”
during the full appetite stage of the 4thinstar would efficiently protect the silkworms from
reinfection by the disease.Plot ex-periments showed that after administrating this chemical the
disease occurrence waslowered by 69.5%,rate of dead worm cocoons decreased by 38.25%and
cocoon spin-ning percentage increased by 50.25%.Trial at many sites in rural areas showed
that thechemical made 63% diseased silkworms recovered,disese incidence decreased by
67.3%and cocoon spinning percentage increased by 52.11%.“Baocanning 2”could be
extendedin oak silkworm raising areas for its profuse supplies and cheap cost.
