| Summary: | This preliminary study was conducted from April to October 2019, and hold the first account
to outline the diversity of aquatic insects with influence to the fluctuating physiochemical
parameters in the pond of Sardar Bahadur Khan Women’s University Quetta. The collection of
722 individuals in total presented four orders (Hemiptera, Ephemeroptera, Diptera and
Odonata) and seven families. These individuals were labeled to generic level as Gerris sp.,
Notonecta sp., Anopheles sp., Thaumalae sp., Sympetrum sp., Orthetrum sp. and Heptagenia
sp. Shannon-Weinner diversity and Simpson’s diversity index revealed greater values for backswimmers
and mayflies (Notonecta and Heptagenia sp.). Additionally, Margalef’s richness
index was also recorded highest (1.163) for backs-swimmers. Amongst physiochemical
parameters, water temperature was ordinated in Gaussian’s species packing model. This
ordination illustrated wider curve for Notonecta sp. and narrower curve for Anopheles sp.,
suggesting the maximum and minimum tolerance (temperature) range for these species in this
specific pond community. Water pH of the pond also altered slightly and ranged from 9.13-
10.3 during April to August. As of the total dissolve solids (TDS), this study observed a raised
from 253.16 mg/L to 432.11 mg/L till the end. Since aquatic insects play vigorous role in the
stability of aquatic ecosystems, more relevant studies are required to be conducted to evaluate
the broader range of these insects. |
