A predator model with refuge and toxicity is studied. By constructing a suitable Dulac function, it is shown that there is no limit cycle in the first quadrant, thus the globally stability of the equilibrium is proved. Further more, the paper analyzes the influence of refuge, toxicity and harvesting. It is amazing that ① if the death rate of predator is big or the harvesting effort is big, the existence of the predator is unrelated with refuge; if the death rate of predator and the harvesting effort are small, and the refuge is small enough, the population of both species is increased as the increase of refuge;② if d2=0, the increase of d1 has no influence on the prey population, while the population of predator is decreased.

研究一类有避难所、毒素作用和外界捕获影响的捕食系统，通过构造恰当的Dulac函数，证明系统在第一象限没有极限环，从而证明了平衡点的全局稳定性；分析了避难所、毒素、捕获作用对该系统最终种群数量的影响，发现：①当捕食者的死亡率大或其被捕获得多时，两种群的绝灭与避难所的存在无关；当捕食者的死亡率小、被捕获得多且避难所足够小时，随着食饵避难所的增加，捕食者种群数量也随之增加；②当毒素d2=0时，毒素d1的增加对食饵种群最终数量没有影响，而使捕食者种群数量下降。

A fumigation of aromatic oil of Litsea Cubeab was used to discharge the pollution aflatoxin B_1 from Euryale feroe Salisb.

The effect of Coriaria lactone on amino acid nerve transmission substance: Coriaria lactone is a kind of nerve toxicant can made amino acid nerve transmission substance content of insect change and the content of GABA increase obviously, the content of Glu change little or decrease slightly.

马桑毒素对昆虫氨基酸神经递质的影响：马桑毒素是一种神经毒剂，作用于昆虫引起体内的氨基酸神经递质含量发生变化，其中GABA含量明显升高，GLU含量变化不大稍有下降，并且马桑毒素侵入虫体后，试虫具有兴奋-吐出中肠液-瘫软-昏迷-死亡的症状，表明马桑毒素是试虫的神经传导中GABA的特殊拮抗剂。

The injectable hemocoelic potency LD (50 of toxin Ⅲ was 0.18 μg/larva against Galleria mellonella fifth_instar larvae.

SDS-PAGE图谱显示毒素Ⅰ和毒素Ⅱ是由多个多肽组成的复合蛋白，而毒素Ⅲ只分离出一条多肽。

So the steps to decrease the level of aflatoxin and to prevent the peanut from being re-contaminated by aflatoxin should be taken as the critical control point. The measures to control the moisture content and remove unsound kernel including moulded kernels, damaged kernels, sprouted kernels and immatured kernels should be taken as the measures to prevent and control aflatoxins in peanut.

Under the selection pressure of crude toxin filtration, three kinds of treatment methods and four kinds of phytotoxin concentrations were used to screen the blast-resistant callus phenylalanine, The result indicated that the crude toxin filtration inhibited evidently the callus induction, subculture and differentiation, with the increasing of the toxin concentration, the inhibiting getting enhanced.

以稻瘟病病原菌粗毒素提取液为选择压，对水稻进行抗病性筛选，结果表明：粗毒素提取液对水稻愈伤组织诱导、继代及分化有明显的抑制作用，抑制程度随毒素浓度提高而增强，且品种间差异显著。

Armigera and M. separata mid-gut juice, but, other less than 60kD proteins also can be got by M. separata mid-gut juice .4 Many Bt Cry1AcE toxins can be got by the method of precipitate and resolve, which have high purity.
