Mylabrids: Bruchus pruininus Horn deposits eggs in the seed capsules 
in Hawaii, but the larvae can not survive in the plant; Zabrotes subfasciatus 
(Boh.) lays eggs on the seeds in Germany, and the report indicates that the 
larvae die upon eating the cotyledons; and Tribolium castaneum (Hbst. ) is not 
able to survive in seeds, according to records made from examination of 
samples of seed, husks, and sweepings from the floors of storehouses in 
various parts of the Soviet Union. 
The anthribid Misthosimella ricini Jordon destroys the ripening seed 
in the Italian Somaliland. 
Typhaea st ercorea (L.) and Carpop hilus dim idiatus (F. ) occur in the 
flowers in Italian Somaliland, but the insects live on waste vegetable matter 
and are not partial to the castor-bean plant. 
There are very few records in the literature of damage to castor-bean 
plants by grasshoppers. The insects feed abundantly on the seedlings and 
to some extent on older plants in Turkestan; they also attack the plant in 
Australia. C hroto g onus trachypterus (Blanch.) occurs sporadically in the 
plains and the lower slopes of the hills in India, causing considerable dam- 
age when numerous. Cy rtacantha cris tata r ica (L.) is injurious in southern 
India and in the Italian Somaliland. Zonocerus elegans (Thunb.) is injurious 
in Tanganyika. 
Sch is tocerca gregaria (Forsk.) causes serious injury in the Italian 
Somaliland, but in Senegal, even when swarms were observed to damage a 
variety of other plants, the castor-bean plants were not attacked. S. impleta 
(Walk.) was swept from the plants in Costa Rica. Swarms of S. paranensis 
(Burm.) sometimes attack the castor-bean plants along with other plants in 
Venezuela. 
The tettigonids Conocephalu s c inereus Thunb. and Microcentr um sp . 
were swept from the foliage and Syntechna tarasca (Sauss.) was observed 
feeding in Costa Rica. 
A big brown cricket, Brachytrupes portentosus (Licht.), feeds on 
practically all plants in India; it fed on shoots and leaves of the castor- 
bean in a laboratory there. 
Thrips: Sc irtothrips dorsalis Hood was originally described from 
shoots of castor-beans and chilies in southern India. Anaphothrips a lter - 
nans (Bagn.) was collected from the leaves in Italian Somaliland. Reti - 
thrips syria cus (Mayet) breeds in the foliage in Egypt. Partheno thrips 
dracaenae (Heeger) was intercepted at a port of entry into the United States 
on castor-bean from England. 
Among the dipterous insect pests of castor-bean the following have 
been recorded: Chaetodacus correctus Bezzi in India; Camptomyia r>"'ni.
