LATHYRUS INSECT PROBLEMS

Aphids suck plant juices and heavy infestations may cover   
the leaves with sticky honeydew.                            

The greenhouse leaf tier feeds on the undersides of the     
leaves.  The insect also rolls and ties the leaves          
together.                                                   

The corn earworm feeds on the buds and foliage.             

The pea moth infests the pods spoiling the seeds.  Silk     
and excrement can be seen when infested pods open.  The     
pods turn yellow and ripen prematurely.  This insect is     
usually not a problem unless sweet peas are grown near      
garden peas.                                                

Four-lined plant bug causes brown sunken spots on the       
leaves.  The insect is only occasionally found on Sweet     
Pea.
