Okra 



The insect enemies of okra are not numerous. The pods are 

 often attacked by the corn ear-worm and the buds and leaves 

 are injured by the caterpillar of the gray hair-streak butterfly. 

 The plants are also attacked by the spinach aphis and melon 

 aphis and are often defoliated by the okra caterpillar. 



The okra caterpillar, Anomis erosa Hiibner 



Okra and roselle are likely to be defoliated by a green looping 

 caterpillar related to the cotton worm. This insect also feeds 

 on several species of hibiscus, abutilon, hollyhock and on 

 Urena lohata and is occasionally found on cotton. It ranges 

 throughout the southern United States, the West Indies,
