Abstract

For the first time R. ferrumequinum activities of its food resources systems research natural state. Using acoustic sampling method to obtain of R. ferrumequinum activity at all sampling points frequency predation activities in R. ferrumequinum, the peak of each sampling point the insects, insects have been identified to the Division, at the same time, captured by light trapping. Using correlation analysis, one-way ANOVA, regression analysis revealed that the relationship between of R. ferrumequinum activity frequency and food resources and its variation with the month and night time periods. Obtained using fecal analysis of R. ferrumequinum in June, July, August, feeding habits. The main conclusions are as follows: 1. R. ferrumequinum activity rate is closely related to insect resources. The number of bat activity Lepidoptera significant positive correlation (r = 0.831 (~ *), P = 0.011, n = 8), that is, with the increase in the number of Lepidoptera bat activity significantly increased; significantly with the insects, the total number of positive correlation (r = -0.812 (~ *), P = 0.014, n = 8), insect weight significantly positive correlation (r = 848 (~ * ~ *), P = 0.008, n = 8). However bat activities and Lepidoptera percentage (r = -0.571, P = 0.140, n = 8), the the coleopteran insects quantities (r = 0.343, P = 0.406, n = 8), the Coleopteran insects percentage (r = -0.376 , p = 0.358, n = 8) and insect diversity (r = 0.231, P = 0.582, n = 8) are not significantly correlated. 2 R. ferrumequinum feeding habits of Lepidoptera and Coleoptera mainly depending on the month. In June, R. ferrumequinum feeding habits of Lepidoptera accounted for 68.99%, Coleoptera insects, accounting for 30.07%; July, Lepidoptera decline in the proportion accounted for 57.25% of the feeding habits, Coleoptera increase accounted 39.07%; August, the proportion of Lepidoptera in the feeding habits continue to decline accounted for 35.15%, Coleoptera significantly increased its share of 51.29%, both still is the main food of bats, but the month Hymenoptera than 6,7 a significant increase in the proportion of the month to 11.2%. 3 R. ferrumequinum frequency relationship with food resources activities depending on the month. June bat activity frequency and Lepidoptera, the number was significantly significantly related (p = 0.015 <0.05) insect total quantity was significant with related (p-= 0.031 <0.05) and insects other parameters not related, July bat activity frequency times only with scaly wings The number of projects was significantly related (p = 0.008 <0.05). August bat activity frequency is not related with the parameters of all insects. Feeding habits in the insect volume percentage and environment, trapping the insect percentage of the gradual regression analysis showed that, in June significantly with related (p = 0.048 ~ *), in July significantly with related (p = 0.013 ~~ *), in August the correlation is not significant with ( p = 0.166), so you can prove random predation R. ferrumequinum in June and July, August selective predation. R. ferrumequinum activity frequency and food resources relationship with the night time period varies. Was significantly related (p = 0.007 <0.05) in the fourth period of June R. ferrumequinum activities and Lepidoptera insect total number was significantly related (p = 0.001 <0.05) with insect weight was significantly related ( p = 0.012 <0.05) but not significantly correlated with other parameters with. The third period in July the R. ferrumequinum activities and Lepidoptera insect numbers were significantly correlated (p = 0.029 <0.05) with insects, the total number was significantly related (p = 0.001 <0.05), but the other parameters not significant. Was significantly related (p = 0.001 <0.05) in the fourth period of August R. ferrumequinum activities and Lepidoptera insect total number was significantly related (p = 0.01 <0.05) the insect weight were significantly correlated ( p = 0.021 <0.05), but with the other parameters no significant correlation.
