对马尾松毛虫质型多角体病毒（Ｄ．ＣＰＶ）添加辅助剂的增效。试验表明：在Ｄ．ＣＰｖ中分别加入１％活性炭、２０％轻质碳酸钙、０．２％墨汁水三种辅助剂，在林间试验校正死亡率达８０．６％以上，比单纯病毒防治松毛虫效果好。Ｄ．ＣＰＶ浓度为２×１０￣６ＣＰＢ／ｍｌ加５０％甘油贮裁（冰箱２一４℃）１４个月，仍有较强的活性，致毒校正死亡率达７３％，比未加甘油的病毒冰箱贮藏、常温贮藏分别增效８％、２９．２％。
Synergistic addition of adjuvant to Dendrolimus punctatus-type polyhedrosis virus (D.CPV). Test shows: in D. CPv were added 1% activated carbon, 20% light calcium carbonate, 0.2% ink ink three adjuvants, in the forest test corrected mortality of 80.6%, better than the simple virus prevention and control of pine caterpillars. D. CPV concentration of 2 × 10 ~ 6CPB / ml plus 50% glycerol storage (refrigerator 2-4 ℃) 14 months, still strong activity, the lethality corrected mortality rate of 73%, compared with glycerol without the virus in the refrigerator Storage, storage efficiency at room temperature, respectively 8%, 29.2%.
