Study On Cockroach Population Distribution And Seasonal Fluctuation Tendency Investigation In Taiyuan Railroad Area

Objective : Through this investigation , analyzing and comparing the two monitoring method (medicine-defying law with glueing-catching law ) in cockroach density monitoring and preventing from and making result using value examine, thus choose to investigate by suitable method the cockroach of Taiyuan railway district at present encroaches on the growth and decline trend of state, population's distribution and season, for better rationally use medicine and because when because develop the activity of killing ground,theoretical foundation offer for controlling cockroaches to endanger effectively.Method: (1) Investigation object:Take the Taiyuan railroad area Taiyuan station, the Taiyuan northstation, the Taiyuan vehicles section (passenger arranges in ordergarage to stop, overhaul), the Taiyuan train attendant apartment as the investigation object. (2) Investigation method:①Sticks catches: the law to adjust the check cloth to put the unification specification to stick thecockroach board, with the fresh sweet bread for the bait (2 grams/piece),each 15m2 standard cloth 1, sets to the cockroach activity place, lateputs the early morning to receive, and counts the classification. Eachcloth puts many to 10, in the spot various places each time adjuststhe check to be relatively fixed.②Medicine stirring up method:In respectively adjusts the check and the cloth puts sticks thecockroach board similar environment place, with kills the insect gasspray medicinal preparation to the panel place wall, the object slitcarries on the striation to spray, after 10 minutes records thecockroach number and the classification which stirs up.③Warm humidity monitor :When each time carries on the population density and the seasonalfluctuation investigation, the determination accent checks inside andoutside various places room the warm humidity. Passes the airseasoning wet thermometer gauze strip with distilled watermoist DHM2, the applied spiral spring, is hanging the table with thebreath belt altitude, after 10 minutes readings.④The cockroach population appraises: Will use to stick catches the law or the medicine stirring up methodcapture cockroach under the dissecting microscope, carries on theappraisal by the specialist according to the cockroach type retrievaltable.⑤Control time:From January, 2006 to December, each month of middle ten daysinvestigates a time, to uses the drugs has processedResult: (1)Glue, catch law with medicine defy law's result compare: Through glue, catch to the whole year law and medicine defy law cockroach density mate order and examine and person who encroach on mate t examine, glue, catch law adult density (0.0779/ board) higher than medicine defy law adult density (0.0244 / dot, notably), (z=-2.29, p=0.022), glue, catch law nymph density(0.4193/board) higher than medicine defy law nymph density (0.0464 /dot, notably), (z=-2.353 ,p=0.019), glue, catch law total density (0.4968 / board) higher than medicine defy law total density (0.0716 / dot,notably), (z= -2.432, p=0.015); Glue and catch the law encroaching on rate every year (12.4%±7.2479) is higher than the medicines and surge law encroaching on rate notably(2.85%±2.42345)(t=4.787,p=0.01). (2)The regional cockroach's population's distribution of railway of Taiyuan and density growth and decline trend: Taiyuan monitoring points catch adults together the whole year such as area such as railway: 745, male and female than 1.45:1, all is Germany little Lian(Blattella germanica); The growth and decline trend of cockroach season: With glue, catch France investigate Taiyuan railway area have cockroach activity every year while being the whole, cockroach nymph density, total density have the tendency to rise month by month from May, drop in December, 5, 7, 9, 10 among them, it is relatively high in November. Cockroach's adult's density growth and decline trend is not obvious, by 5, relatively high in October. (3)The regional cockroach of railway of Taiyuan encroaches on the situation: Glue, catch law with medicine defy law person who encroach on measure result compare, glue, catch law 12.4% of encroaching every year, but medicine surges 2.85% of encroaching on rate every year. Through mating monthly, t examines, has significance differences between Glue- catching law to medicine defy law by mating (t =4.787, P<0.001). Monitor the unit cockroach differently and encroach on the situation: Apartment(6.18%) most getting high to stand for Taiyuan; secondly, Taiyuan station (6.02%);thirdly,Taiyuan rolling stock section (4.82%); Taiyuan has not found that there are cockroach activities in Taiyuan north. The cockroach of different places encroaches on the situation: Food and beverage place most high (12.68%), secondly for sell goods (5%) department, the third guest room (apartment, station) (3.21%), the fourth waiting room (1.67%), there has not found in the overhaul workshop and office building and vehicle.. Encroaching on rate growth and decline trend, investigate, the encroaching on rate of cockroach has the tendency to rise from May by glueing and catching Law, among them it is relatively high with May, September - November, drop in December. (4)The comparison that the internal and external temperature of the room are angry and wet: There is difference significance (F=25.75, P<0.001) at the internal and external temperature of the room in the whole year, there is no difference significance (F=0.29 P>0.05) in the internal and external humidity of the room in the whole year; Indoor temperature is 11.9℃- 30.1℃, average temperature is 21.05℃; 52%-91.5% in indoor relative humidity, 76.17% of humidity on average, belong to the high wet environment. The variation tendency of season of the warm humidity inside and outside the room: The outdoor temperature rises since March in the whole year, it is the highest in June, begin to drop in November; Indoor temperature and outdoor temperature variation tendency basically identical, with June being the lowest in high December most. Outdoors angry to change much year while being wet, with November being lower in December; Room angry wet year change with most high May, June, relatively low in December in November, with angry and wet and basically identical outdoors. (5)The impact on the encroaching on rate of cockroach, cockroach's density growth and decline trend of the warm humidity in the room: Glueing has no positive correlation of significance to catch law's succeeding, nymph, total density and temperature, adult density and relative humidity have significance shoulder relevant, nymph density, total density and relative humidity have high significance to shoulder relevantly (r little = - 0.664, P adult = 0.018, N=12; r tota = - 0.671, P tota = 0.017, N=12) . According to season growth and decline trend, the growth and decline of temperature keep the same with cockroach's density, trend of encroaching on rate growth and decline, the growth and decline of the humidity are not totally identical, reduce angrily and wetly identical with downward trend of cockroach densitily only in November - December.Conclusion: (1)By measuring the comparative analysis of the result to two indexes of cockroach 's density and encroaching on rate through two kinds of methods, Glue, catch law superior to medicine defy law. Density season growth and decline investigate person who encroach on investigate and prevent and cure result examine, in cockroach, propose glueing the law of catching first-selectedly; In kill cockroach result examine and kill cockroach in the advanced unit assessment with some other investigations test in advance, medicine defy law because easy to check, investigate cycle to be easy to operate short, propose first-selected medicine surge law suddenly. (2)Taiyuan railway area find Germany little Lian(Blattella germanica) first kind only. (3) Monitor the unit cockroach differently and encroach on the situation: Apartment most getting high to stand for Taiyuan secondly, Taiyuan (4.82%) rolling stock section, attendant of Taiyuan, stands and has not found that there are cockroach activities in Taiyuan north. The cockroach of different places encroaches on the situation: Food and beverage place most high (12.68%), secondly for sell goods (5%) department, the third (3.21%) guest room, the fourth (1.67%) waiting room, overhaul the workshop and has not found in official working and vehicle. (4) The growth and decline change of indoor temperature season keeps the same with cockroach's density and encroaching on rate growth and decline trend, have the tendency to rise from May, among them it is relatively high with May, September - November, drop in December. The indoor humidity does not change much every year, belong to high wet season from January to October, other periods are angry and wet and relatively low, room warm humidity growth in cockroach have influence to breed, temperature may be a main influence factor. (5)Adopt and defend making the activity on a large scale in time in spring winter before the cockroach grow in the peak time breeding, in order to control cockroaches to endanger effectively.
