Abstract
Developmental time, consumption rate and fecundity of Cheyletus malaccensis Oudemans were studied on different stages (eggs, immatures and adults) of Tetranychus cucurbitacearum (Sayed)at laboratory conditions, 32±2°C and 50±10% R.H.
Data analysis revealed a significant effect among different stages except for incubation period at both sexes. Life cycle of female was longer than of male. Duration of female was 28.7, 20.4 and 23.4 days and 17.79, 18.15 and 20.9 days for male when fed on the three preys, respectively. The adult longevity of female showed longer duration (52.4 days) when fed on eggs than male (18.9 days) fed on the same prey. The number of prey consumed and the fecundity were significantly lower when fed on T. cucurbitacearum ( immatures and adults) compared to eggs of the same prey.
Data provide fundamental information for understanding the effect of different prey on development of C. malaccensis.
