研究结果表明：黄原胶与羟丙基淀粉、CMC－Na复配无协同增效作用，黄原胶与刺槐豆胶、魔芋精粉、瓜尔豆胶有良好的协同增效作用，两者或三者按适当比例配合后，耐盐稳定性显著提高，用量比任一单一胶少，而且使用成本大幅度降低，因此复配食品胶在高盐食品中使用具有明显的优越性和广阔的应用前景。

The synergism ratios of piperonyl butoxide to alpha-cypermethrin in these three strains were similar(about 20-fold), which suggested metabolic detoxification probably confers about 20-fold inherent resistance in the B-type whitefly, as PBO is a mixed function oxygenase and esterase inhibitor and glutathione S-transferase is not affinity to resistance in B. tabaci. The synergism ratio of triphenyl phosphate to alpha-cypermethrin in the NJ strain was 12-fold, which implied the synergism of PBO in the B-type whitefly is mainly due to inhibiting esterase activity.

增效试验表明PBO对这三个品系的增效作用均为20倍左右，因为在烟粉虱中PBO即是多功能氧化酶抑制剂，也是酯酶抑制剂，而谷胱甘肽S-转移酶与抗性无关，因此推断代谢酶在B型烟粉虱对高效氯氰菊酯的抗性发展中起到的相对作用可能为20倍左右，而且这种抗性是B型烟粉虱天生的；TPP对NJ品系的增效作用为12倍，说明PBO增效作用主要是由于抑制酯酶而引起的，即代谢抗性大部分由酯酶所贡献。

This paper has made further studies on the synergistic interaction and stability of salt tolerance between xanthan gum and other common food gums. It turns out that there is no synergistic interaction between xanthan gum and hydroxypropyl starch , CMC-Na. Xanthan gum and guar gum ,locust bean gum ,konjak flour have great synergistic interaction. If two or three of them mix with proper proportion, the stability of salt tolerance will greatly improve and the consumption is less than any other simple gum, further more, the cost will decrease a lot. So the complex thickeners have a obvious superiority and wide utilization in high salty food.

The synergists ZB-1 and ZB-6 have both positive synergism to the efficiencies of cantaridin and demethylcantharidin.

助剂ZB-1和ZB-6对斑蝥素和去甲斑蝥素均有增效作用，当助剂最佳加入量为8%时，同浓度ZB-1对斑蝥素和去甲斑蝥素胃毒致死中浓度的增效倍数分别为3.47和3.28倍；同浓度ZB-6对斑蝥素和去甲斑蝥素增效倍数分别为3.52和1.97倍。

Funecide is one of the agricultural antibiotics having intensive nematocidal activity on Meloidogyne spp.. Through the toxicity determination of six synergists(TPP, DEM, PEG, NT, H3BO3, Tween-20)to funecide indoor, we found that three of them(TPP, PEG, and H3BO3) have increased synergistic effect.

The studies on metabolic enzymes、synergists and neurobioassays suggest that the monooxygenases、esterase and decreased nerve sensitity are involved in resistance to pyrethroids in the resistant HJ-R strain . The resistance to both organophosphorus and carbamate insecticides is mainly caused by metabolic mechanisms. The significantly synergistic effects of Pbo infer that the resistance to carbamata may be principally attributable to monooxygenases detoxification.

代谢酶系、增效作用以及神经电生理研究表明，HJ-R种群对拟除虫菊酯类杀虫剂的抗性是由多功能氧化酶及酯酶代谢增强、神经敏感性降低几个因子综合作用的结果；对有机磷、氨基甲酸酯类杀虫剂的抗性主要是由代谢机制引起，与靶标部位敏感性降低机制抗性无关，Pbo对HJ-R种群突出的增效作用，表明多功能氧化酶代谢在对灭多威的抗性中可能起主导作用。

Using a long-term reared housefly population which is very susceptible to pyrethroid insecticides as the susceptible strain, a population collected in 1993 in Shanghai and has been treaded by cyhalothrin as the resistant strain, we bioassayed their susceptibility to organophosphorus, carbamate, pyrethroid and organehloride insecticides. We also investigated the role of metabolic enzymes, i. e. esterase, GST, MFO and of target enzymes, i. e. AChE and 〓-ATPase in resistance to insecticides. Cyhalothrin resistance inheritance, the co-toxicity coefficient of cyhalothrin and methylene dithiocyanate was also studied. The insecticides resistance in adults and larvae of houseflies was compared and the mechanism of resistance differences between adults and larvae was discussed.
