Effect of salinity on the predatory performance of Diplonychus rusticus (Fabricius).
Predatory efficiency of Diplonychus rusticus (Fabricius) was recorded at different prey density with different salinity ranges. When the salinity level (ppt) was increased, the predation rate of the bug decreased. Fifth nymphal stage showed higher predation in the 2, 4 and 6 ppt levels of salinityin both 1 hr and 24 hr period of exposure at prey densities 50, 100, 150 and 200. At prey density 150, adult bugs killed more prey in the 2 ppt level of salinity in both lhr and 24 hr treatments.
