[Abstract]:OBJECTIVE:On the basis of analyzing and comparing the application value of sticking capture method and drug stimulation method in monitoring the density of cockroaches and checking the control effect of cockroaches,to select the appropriate method to investigate and understand the current situation of cockroaches invasion,population distribution and seasonal fluctuation trend in Taiyuan railway area,so as to better control the cockroaches with rational drug use. Hazards provide theoretical basis.
Methods: (1) Investigation subjects: Taiyuan Railway Station, Taiyuan North Railway Station, Taiyuan depot (passenger train depot stop, maintenance), Taiyuan crew apartment as the investigation object. (2) Investigation methods: 1) The investigation point was randomly determined by sticking method to put uniform specifications of sticky cockroach board, with fresh sweet bread as bait (2g / sheet), every 15-2 standard rooms. One sheet of cloth was placed in the place where cockroaches were active, and the cloth was put at night and harvested in the morning, and counted and classified. No less than 10 sheets were placed at each point, and each investigation point was relatively fixed in each place. 2 Investigation points of drug stimulation method were determined by drug stimulation method. Linear spraying of insecticide aerosol was used to spray the wall and object gap at the place where sticky cockroaches were placed in the same place. The number of cockroaches was recorded and classified after 1 minute.3 The indoor and outdoor temperature and humidity were measured at each site during the population density and seasonal fluctuation survey. The wet-bulb yarn was ventilated with distilled water to wet the DHM2 dry-wet thermometer, tightly wound, and the watch was suspended with the height of the breathing belt, and the reading was made after 10 minutes.4 The cockroach population identification will be used. Cockroaches caught by sticking method or drug stimulation method were identified under anatomical microscope according to the key list of cockroach species. _Investigation time: January to December 2006, once a month in the middle of the survey. The interval between the two surveys was not less than 7 days for the drug-treated sites.
Result: (1) Comparing the results of sticking method and drug stimulation method, the density of adult by sticking method (0.0779 cockroaches per board) was significantly higher than that by drug stimulation method (0.0244 cockroaches per point) (z = - 2.29 P = 0.022), and nymph density by sticking method (0.4193 cockroaches per board) was significantly higher than that by drug stimulation method (0.049 cockroaches per board). The density of insects (0.0464/point) (z = - 2.353 P = 0.019), the total density of sticking method (0.4968/plate) was significantly higher than that of pesticide stimulation method (0.0716/point) (z = - 2.432 P = 0.015). The annual average invasion rate of sticking method (12.4% + 7.2479) was significantly higher than that of pesticide stimulation method (2.85% + 2.42345) (t = 4.787 P = 0.01). Long-term trend: 745 adult cockroaches were caught in all monitoring sites in Taiyuan Railway area, the ratio of male to female was 1.45:1, all of them were Blattella germanica; the seasonal fluctuation trend of cockroaches was investigated by stick-capture method. Cockroach activity and nymph density of cockroaches were observed in Taiyuan Railway area all year round, and the total density increased month by month from May to December, and decreased in May, July, September, October and November. (3) Cockroach infestation in Taiyuan Railway area: Compared with the pesticide stimulation method, the average annual infestation rate was 12.4%, and the pesticide stimulation method was 2.85%. Cockroach infestation in different monitoring units: Taiyuan crew apartment was the highest (6.18%) followed by Taiyuan Station (6.02%) and Taiyuan depot (4.82%). No cockroach activity was found in Taiyuan North Station. The rate of cockroach infestation increased from May to December, and it was higher in May, September to November, and decreased in December. (4) Comparison of indoor and outdoor temperature and humidity: There was a significant difference between indoor and outdoor temperature throughout the year (F = 25.75 P < 0.001), and there was no difference in indoor and outdoor humidity throughout the year. The difference was significant (F = 0.29P > 0.05); the indoor temperature was 11.9 30.1, the average temperature was 21.05: the indoor relative humidity was 52% - 91.5%, and the average humidity was 76.17%. The seasonal variation trend of indoor and outdoor temperature and humidity was: the outdoor temperature increased in March, the highest in June, and began to decline in November; the variation trend of indoor and outdoor temperature was basically the same. The annual variation of indoor humidity was the highest in May and June, and the lowest in November and December, which was basically the same as that of outdoor humidity. (5) The influence of indoor temperature and humidity on cockroach invasion rate and seasonal fluctuation trend of cockroach density: stick catching method, nymph and total density had no correlation with temperature. There was no correlation between insect density and relative humidity, but there was a negative correlation between nymph density, total density and relative humidity (r = 0.664, P = 0.018, N = 12:r = 0.671, P = 0.017, N = 12). The trend of seasonal fluctuation of temperature was consistent with that of cockroach density and damage rate, but the fluctuation of humidity was not completely consistent, only at 1. The decrease of gas humidity in 1-12 months coincided with the decreasing trend of cockroach density.
Conclusion: (1) By comparing the results of cockroach density and damage rate, the sticking method is superior to the drug shock method. In the selection of advanced cockroach-killing units and other preliminary experiments, the drug-stimulation method is recommended as the first choice because it is easy to make a sudden investigation, short investigation period and easy to operate. (2) The survey of cockroach population distribution in Taiyuan railway area only found one species of cockroach. The seasonal fluctuation trend of cockroach density shows that cockroach activity occurs every month of the year, including cockroach activity. Cockroaches in different monitoring units were the highest (6.18%), followed by Taiyuan Station (6.02%), Taiyuan vehicle depot (4.82%) and Taiyuan North Station (4.82%). Fourthly, the waiting room (1.67%) was not found in the office and vehicle repair workshop. The trend of cockroach infestation rate showed that it increased from May to the end of the year, and there were two peaks, the highest of which was from May to September to November. (4) The seasonal variation of indoor temperature was consistent with the seasonal fluctuation of cockroach density and infestation rate. The indoor humidity changes little from January to October, and the humidity is low in other periods. The indoor temperature and humidity have an effect on the growth and reproduction of cockroaches. Temperature may be the main influencing factor. (5) Large-scale control activities should be taken in time in winter and spring before the peak of cockroaches'growth and reproduction and activities. Control cockroach harms.
