Habitations, insects, month, behavior


Insects are one of the most successful organisms of the tropics and have survived many geological changes in the past and play crucial roles in ecosystem functioning. The present study examined insects’ monthly abundance and habitation behavior in the Palamalai region, Periyanaickenpalyam road from November 2020 to JULY 2021. The order Hymenoptera was rich in our area .n=6, Genera (n=13) and species (36) followed by the Lepidoptera family (n=10), genera (n=17), and species (n=21). According to the species diversity, Orthoptera were less in number (n=2). In monthly observation Hymenoptera were abundant in May (n=268) followed by Lepidoptera in July (82spp), coleopterans were rich in February moth (n=65), and Orthoptera abundant in June n=18. The Hemiptera (n=8, march), Odonata (n=8, December) and Diptera (n=6, march) were less in our area. The habitation behaviors of insects were observed in different areas like residential, open fields and agricultural areas. In the Simpson calculation, open fields were rich in diversity (n=1.24) agriculture (n=1.16) and residential fields (n=1.13). The diurnal and nocturnal behaviours were also noted. It can be concluded this study provides clue information on insects’ monthly abundance with habitation behavior. Statistical works are also made for the accurate assessment of the data by using Alpha diversity measures such as the Simpson index, Shannon index, Margalef's richness index Relative dominance etc. Hymenoptera and Lepidoptera were the most dominant orders in this area. The order Diptera was less in our area. The month-wise and nocturnal and diurnal habitats analysis also made by this study, the months of April and May stood out with maximum diversity.
