When peas and beans are grown under poor conditions 

 they are prone to attacks of various pests such as the 

 Black Fly and the Pea and Bean Weevil. 



The Black Fly or Thrips ruins the plants by making its 

 home on the leaves or more generally on the flowers, 

 sucking the sap from them and causing the petals to 

 shrivel, consequently preventing the formation of the 

 pods. To suppress this pest the Board of Agriculture 

 suggest that all likely shelter for them should be destroyed. 

 Old sticks used for runner beans or peas are a source of 

 much danger. They, and the haulm, should be burnt as 

 soon as the crop is seen to be irreparably damaged. It 

 is certainly advisable not to grow leguminous crops close 

 to where infection has been. Spraying may do some good, 

 but in the case of the blossom-attacks it is a doubtful 

 method. For leaf-destroying thrips there is nothing like 

 pyrethrum wash, formed by adding one ounce of fresh 

 pyrethrum to two gallons of soft water and an ounce of 

 soft soap. Liming the ground is also useful. 



Peas and beans are subj ect to attacks by the Pea and 

 Bean Weevil, but the injury is frequently attributed to 

 sparrows and slugs, because the weevils are not by any 

 means easily seen, and readily fall to the ground when 

 alarmed. The weevils eat the leaves and young shoots of 

 the plants and the larvaa devour their roots. 



" The beetles lay their eggs either upon or just beneath 

 the soil close to the roots of their food plants. The eggs 

 hatch into small, white, footless, wrinkled grubs, with brown 

 heads and biting jaws. These grubs feed on the roots of 

 peas, beans, clover, sanfoin, and lucerne. When full grown 

 the larvse are about one-fourth of an inch in length.
