Studies on predatory potential of larva and adult of H. octomaculata on A. pisum was carried out under laboratory conditions during January 2018 to April 2018.The results showed that the first, second, third and fourth instar larva consumed an average of 15.72 ± 2.66, 25.72 ± 4.79, 53.58 ± 10.93 and 88.94 ± 14.79 aphids, respectively. The total larval consumption was 183.96 ± 17.97 aphids during its total developmental period when reared on A. pisum. The mean daily consumption of first, second, third and fourth instar larva was 12.09 ± 3.03, 14.11 ± 3.36, 21.61 ± 5.60 and 25.38 ± 4.

Biology and feeding potential of Coccinella septempunctata was studied in the laboratory condition during 2013 in different months pertaining to different temperature regimes on Cowpea aphid, Aphis craccivora. During the cooler months of January and November, the life stages are prolonged and in the warmer months of March and May the life stages are shorter for the coccinellid. In January, when the mean temperature was 21.7ºC, the total developmental period from egg to adult stage, took 22.4±0.67 days whereas, in May, at 32.7ºC, the total developmental periods was 15.2±0.

Phytophagus mites are gaining importance at present since their incidence is high. Farmers rely only on acaricides and other chemical pesticides for the management of these mites results in destruction of natural enemies, pesticide resistance and pesticide residues in crops, environment pollution etc. Hence, there is a need to find alternate to manage the phytophagous mites. Exploitation of natural enemies viz., predaceous insects, predatory mites and acaropathogenic fungi are the tools in pest management programmes.

Most of the concern about mercury focuses on lakes and other aquatic ecosystems, such as rivers, streams, wetlands and oceans. The levels of mercury found in terrestrial environments are usually not high enough to threaten the health of wildlife and humans. But some aquatic environments favour the transformation of mercury into its more poisonous form — methylmercury — and it is the bioac- cumulation of methylmercury in fish and marine mammals that presents a potential problem when they are consumed by humans.
