ABSTRACT
The study was
conducted to investigate the effect of seasonal changes on distribution and
abundance of insects in three habitat types in Umudike Area, of Abia State,
Nigeria. The specific objectives were
to: to investigate the seasonal changes
in insect diversity of three habitat types in Umudike Area, Abia State, to
compare the abundance of selected key insect species during the wet and dry
seasons in three habitat types, to determine the status and distribution of
different insect groups in the study sites, to generate baseline data for
kick-starting long-term monitoring of the insect’s life of the area. Insects
sample were collected weekly from each sampling sites using locally made sweep
net, picking was done with hands or forceps. Data were collected for five
months with two months wet season (June and July) two months dry season
(November and December) and period one month as transition (April) 2018. The
results obtained were presented using descriptive statistics such as graphs,
tables and chats. A total of 1264 insects spread across nine (9) orders,
twenty-eight (28) families and forty-three (43) species were recorded. The
different insects sampled, were higher during the wet season as compared to the
dry season. Although insect species were significantly most abundant in the
Fish farm site followed by the Experimental farm site. Relict forest had the least abundance. Shannon
diversity index suggested that insect diversity was highest in Relict forest
during the wet season. Species evenness
based on the pielou’s index suggested high spread of the species across the
habitat types and seasons. In Relict forest, the most abundant insects order is
Hymenoptera. Meanwhile, Odonata
(damselflies and dragonflies) were most abundant in Fish farm site. While Orthoptera
were most abundant in Experimental farm site. In all the three habitat types
sampled Orthoptera were most abundant insects order. Meanwhile among the insect
families recorded Acrididae was most abundant. Insect species were most
abundant at the relative humidity between 93 –97% and at temperature of 27
