The ladybird beetle, Harmonia sedecimnotata (F.) was studied in biology, life table, consumption rates,
molecular characterization, and feld evaluation. The net reproductive rate (R0), based on the agestage and two-sex life table, was 43.2 eggs/individual. The female adults lived longer (68.1 d) than the
male adults (62.9 d). The rate of consumption increased with progress in each stage of development.
Compared to the other larval stages of the predator, the fourth stadium consumed most quantities of
Aphis gossypii Glover nymphs (Hemiptera: Aphididae) (200.4). Both female (2214.6) and male (1792.4)
consumed more prey (nymphs) than larvae. The net rate of consumption was 1458.92 nymphs of melon
aphids. There was no variation in the sequences of the two nucleotides out of 583bp, H sedecimnotata
China (EU392410) and India (MG720024). Our investigations demonstrated that inoculative release of
30 or 40 or 50 adults per 100m2
attained high reduction of aphids (>90%). Thus, it may be recommended
the release rate of 40 adults per 100m2 to suppress the eggplant aphid population. H. sedecimnotata is
therefore one of the most promising biological control agents for cotton aphids that can be achieved for
instant control through an inoculative release of adults.
