Effect of Phosphine and Methyl Bromide Fumiganon on Eggs and Larvae of Rice Moth Corcyra Cepha-Lonica S. A Common Stored Grain Pest
Among the insect pests that attack 
stored groundnut, rice moth Corcyra ~ephalonica 
Stainton is most important- It 
is polyphagous in nature and cosmopolitan 
in distribution. .Its ability to develop at 
low humidities ( < 20 "/, RH) may account 
for its prevalence in the semi-arid tropics 
(SAT) over other stored product lep.idopterous 
pests (Dick, 1987)- The irifestation 
in groundnut results in both qualitative 
and quantitative losses. C. cephalonica 
is the most co.mrnon insect pest, often 
encountered during the visual examination 
of seed samples meant for export. 
Though this species is cosn~opolitan in 
distribution and has attained economic 
importance in several crops, very limited 
work has been done with respect to its 
control by fumigation. Hence this study 
was undertaken to evolve effective, easy, 
and economic fumigation schedule to 
control this pest to ensure better sanitation 
of outgoing seed.
