Abstract Spotted stink bug, Perillus bioculatus female bug lays 25-30 rounded black eggs. Eggs hatch in 5-6 days. The 1st instar nymph lasts for 3.33 days (ranged 3-4 days), however the second instar nymphal period is completed in 3.67 days (ranged 3-4 days), while the 3rd instar takes 4 days (ranged 4 days). The 4th and final instars nymph lasts for 4.67 days (4-5 days), however adult period lasts 6.67 days (ranged 6-7 days). The P. bioculatus was found to complete its life cycle on an average in 22.33 days (ranged 20-24 days) in the laboratory. In a laboratory experiment on feeding potential of different stages of bug showed that a single bug consumed 22.0 grubs (ranged 20-22 grubs) during its life period. This bug is recorded as a limiting factor of Z. bicolorata.
