Abstract
Biology of rice moth (Corcyra cephalonica, Stainton) and its ecofriendly
management
Jayshree Jhala* Prof. Anil Kumar Vyas , The present investigation entitled “Biology of rice moth (Corcyra
cephalonica, Stainton) and its eco-friendly management” was carried out under
laboratory condition, Department of Entomology, Rajasthan College of Agriculture,
MPUAT , Udaipur during, 2017.
The experiment was conducted to assess the effect of five host viz., maize,
rice, pearl millet, wheat and sorghum on the biology of C. cephalonica. The result
revealed that the minimum larval period (32.40 days) was recorded on sorghum and
maximum was on wheat (43.15 days). The maximum larval weight was recorded on
sorghum (52.55 mg) and minimum on wheat (42.00 mg). The minimum pupal period
was recorded on sorghum (9.45 days) and maximum on wheat (10.20 days); while
maximum pupal weight was recorded on sorghum (38.50 mg) and minimum on wheat
and maize (33.95 mg). The minimum hatching period (4.00 days) was observed on
sorghum and maximum on wheat (5.50 days). The maximum adult emergence was
recorded on sorghum (80.00%) and minimum on wheat (68.75%). The Growth Rate
Index was maximum on sorghum (1.73) and minimum on wheat (1.18). The highest
mean fecundity of female (301.75 eggs/female) was recorded on sorghum and
minimum was on wheat (230.75 eggs/female). The maximum adult longevity period
(10.50 days) was recorded on sorghum and minimum on wheat (8.25 days). The
minimum developmental period was recorded on sorghum (46.20 days) and
maximum was on wheat (57.80days).
The result of studies conducted on efficacy of different plant products against
C. cephalonica in rice revealed that the highest larval mortality (83.00%), highest
pupal mortality (10.00%) and minimum adult emergence (7.00%) were recorded in
rice grains treated with neem seed powder after 40 days of release and it was
concluded that the neem seed powder was most effective. The minimum larval
mortality (68.00%), pupal mortality (6.00%) and maximum adult emergence
(26.00%) were recorded on eucalyptus leaf powder.
