Abstract:Adult females of Tetranychus urticae Koch were placed on cotton leaves ('Acala SJ-2') treated with methyl parathion (5E) or phosphoric acid (85%). The number of eggs deposited by F1 females was recorded daily and compared with mites ovipositing on untreated plants. Comparison of average daily oviposition and life tables statistics were made for each treatment on both field and greenhouse plants.
In the field, mites on the methyl parathion-treated plants deposited a significantly (P < 0.05) greater number of eggs for the first 4 days than those on the untreated plants. Mites on the phosphoric acid-treated plants deposited a significantly greater number of eggs on the second and third days than those on the untreated plants. Life table statistics paralleled the trends in increased population growth potentials for mites on the treated plants. Greenhouse results were less conclusive.
