Abstract:

Bacillus thuringiensis is a naturally occurring soil bacterium that produces a protein which is toxic to insect pests. Mirid bugs apparently prefer to feed on the apical meristematic tissues, developing floral buds and developing seeds. Feeding damage can cause floral bud and young fruit destruction, resulting in severe reductions of seed set. Biology and morphometrics of cotton mirid bug (Creontiades biseratense), were studied at College of Agriculture, Raichur, UAS Dharwad under laboratory conditions. Bio-ecology of cotton mirid bug (Creontiades biseratense) indicated that eggs are transparent nacreous white, cigar shaped laid signally or in groups on squares, tender bolls and leaf tissues. The bug had five nymphal instars with a mean nymphal duration of 15.27 days. The total lifecycle of male and female was 34.92 and 42.72 days respectively and 35.52 and 44.22 with a mean fecundity of 135.40 and 140.90 eggs per female without honey and with honey respectively at room temperature.
