ACUTE TOXICITY OF NEEM BASED PESTICIDES ON LYMNAEA ACUMINATA

KIRAN SINGH and D.K.SINGH*

Department of Zoology, University of Gorakhpur, Gorakhpur - 273 009, India

ABSTRACT

Molluscicidal activity of four neem based pesticides viz. neemgold (24 hr LC50; 137.18 mg/1), neemazal- T/S (24 hr LC50; 116.39 mg/1), multineem (24 hr LC50; 74.67 mg/1) and rakshak (24 hr LC50; 82.37 mg/1), against the snail Lymnaea acuminata was studied by the method of Singh and Agarwal (1981). Multineem (24 hr and 48 hr) and rakshak (96 hr LC50); 10.15 mg/1) are potent in short and long term exposures (72 hr and 96 hr), respectively.


ABSTRAK

Aktiviti moluskisid daripada empat pestisid berasaskan neem seperti neemgold (LC50 24jam; 137.18 mg/1), neemazal- T/S (LC50 24 jam; 116.39 mg/1), multineem (LC50, 24 jam; 74.67 mg/1) and rakshak (LC50 24 jam; 82.37 mg/1) terhadap siput Lymnaea acuminata telah dikaji dengan kaedah Singh dan Agarwal (1981). Multineem (24 jam and 48 jam) dan rakshak (LC5096 jam; 10.15 mg/1) adalah poten akibat pendedahan jangka masa pendek dan panjang (72 jam and 96 jam) masing-masing.

Key words : Neem based pesticides, snail
