Abstract
Study on “Biology of lesser
grain borer (Rhyzopertha dominica) on wheat” was carried out in PG
laboratory, Department of Entomology, N. M. College of Agriculture, Navsari
Agricultural University, Navsari during 2022-23 on the wheat variety Lok-1
Study was carried out at ambient temperature of 30±1ºC and 70±5% relative
humidity. The eggs were laid on grain surface, nearly oblong shaped
with round ends and glued singly over the grain. Average fecundity of R. dominica was
46±6.43 eggs/female. The average incubation period of eggs was
5.58 ± 0.79 days. The average hatching percentage was 94.08±1.75 per cent. The
entire development of larval stage was completed inside the grain. Pupation
takes place inside the hollow shell of the seed. The average development period
was 46.94±2.58 days. The average pre-oviposition period was of 5.64±1.93 days.
The upper and lower limits of oviposition were 25 days and 20 days,
respectively. The post-oviposition period varied from 2 to 6 days with an
average of 4.2±1.11 days. The average adult longevity of male and female were
14.91±0.99 days and 21.88±1.86 days, respectively. Sex ratio of (male: female)
was 1.23:1.04. An average life cycle of male adult beetle was 60.52±2.87 days
and female were 69.96±2.02 days.
