At present, chemical control is an important way to grasp the bait of Blattella germanica. Along with the application and resistance of new type of bait, very need to bait the eve of the two constitute a component of hygienic insecticides and bait base research, except with insecticide selection pressure on the outside, whether with German cockroach sensitive sense of smell, touch feeling infection is to insecticides perception to understand the resistance, thereby avoiding action related and bait some group divided into impact on the feeding action of Blattella germanica, while monitoring the German cockroach, Blattella germanica population divergence of frequently used bait insecticide resistance and action selection. Research results can preliminary understand action in Blattella germanica anti drug action can perhaps pointing bait insecticide scientific and reasonable application, and can expand the Blattella germanica resistance mechanism research ideas for Blattella germanica control supply management strategy. 1, German cockroach nymphs age difference for signs of research from Blattella germanica single egg pods stop captive, daily observations and recorded the molting and age development progress, determination of nymphs of head width, body length and weight etc. biological characteristics, through statistical analysis of the important sign value to determine the nymphal instars. Results: in the absolute stability of the premise, the difference between the age of weight change is the most significant, followed by the body length. According to body weight, body length and head width, it is concluded that the individual. In captivity under the premise, German cockroach nymphs were experience six age and Blattella germanica age and head width, body length or weight were positively related to, and the difference is statistically significant; the correlation coefficient (R) separation for: 0.9539, 0.9854, are 0.9879. 2, Blattella germanica to stomach poison resistance determination of the prerequisite and basis of the bait to Blattella germanica male adults for testing insect, determination of light and food of the geometric position and hunger level influences on food choice; in different development stage and of the rest of the German cockroach, Blattella germanica to test insect, to feeding times and stay time, separating and selecting, take the love of food base bait. Results annotations, weak light on male adult feeding beneficial; similar premise, the geometric position of food fed to male adults without obvious effect; young (L1 / L2), aged L4/L5 and male and female adult hunger 2D than not hungry, starved for 1 day and hunger 3D separation, on food choice differences are significant, hunger 2D determination of food difference better, selectivity of food from high to low in order for: bread, pork and pine > milk > mouse feed, biscuits > malt sugar > Nianye flour > tomato sauce, wheat flour. So can choose pork floss or bread as bait, launched the stomach poison resistance monitoring. 3, differences between the populations of Blattella germanica to fipronil and acephate sensitivity study to stomach toxicity determination of differences in China under the hunger situation in different regions of Blattella germanica populations for regular use of insecticides recommended doses of LT5o and LC5o on rare pesticides, results note: Jiangsu population is not under the premise of hungry pork floss 1% acephate bait show significant sensitivity, under the premise of hunger in the Ji'nan population showed significant sensitivity of bread; Jiangsu and Ji'nan population without starvation of 0.05% fipronil baits showed loose pork sensitivity significantly, but the hunger condition, laboratory population pork bait agent; laboratory population, Jiangsu population and Ji'nan population of Blattella germanica in the premise of hunger and not hungry with bread and pork floss showed significant sensitivity for 1% acephate bait Pine; no bread and hunger in the premise of difference, and in not hungry expressed strong tolerance; as long as the Jinan population not hunger under the premise of 0.05% fluorine fipronil bait agents did not show the sensitivity difference and other circumstances have said a significant sensitivity difference; fluorine fipronil bait agent resistance results show: the pork floss for bait agent, laboratory population, Jiangsu population and Jinan population which and lc95 had no significant difference; with a bread based bait, Jiangsu population and Jinan population virulence difference of acephate bait agent resistance results show: Jiangsu population and Jinan population virulence indifference, and pork based bait more toxic. 4, differences between the populations of Blattella germanica to often use pesticides action selection in the laboratory using natural selection method of fundamental observation records of Jiangsu and Ji'nan populations of action tendency often use insecticide fipronil, acephate and deltamethrin recommended dose of bait, results of invention: Jiangsu and Ji'nan populations of German cockroaches, no matter bread still pork floss based bait, behavior choice are more likely to contain acephate bait, and the difference is obvious and the trend to do not contain deltamethrin baits, and the difference is obvious; but the two farming population to 0.05% and fipronil action response is not significant, palatability and guiding force of different resistance, 5 monitoring of insecticide to insecticidal bait of the German cockroach Blattella germanica to insecticidal bait resistance monitoring measures the premise for insects: Body: complete and vivid Ankang male adults; disposal of hunger 2 days; experimental conditions: temperature (26 / 1), absolute humidity (60 / 5)%; light: weak 目录: |
