together as their pests may be very similar. Mustard, for example, 
might be expected to be included under oil-seeds, but it will be more 
convenient for our purposes to take it under Cruciferae together with 
cabbage and other allied crops. 
Sresamum (Sesamum indicum). 
[Til—North India. Gingelly—South India. ] 
Sesamum seedlings are sometimes damaged by Brachytrypes porten- 
tosus, which we have just discussed under the heading of indigo. 
In Bengal, plants about a foot high are damaged in July and August Mr. Sen. 
at Dacca by Brachytrypes. 
A good many pests occur on the leaves of Sesamum, the worst being Mr. Fletcher. 
Antigastra :— 
Pachnephorus inpressus. 
Tanymecus chloroleucus. 
Anomala antiqua. 
Diacrisia obliqua. 
Amsacta moore. 
Acherontia styx. 
Pericallia ricini. 
Laphygmna exigua. 
Antigastra catalaunalis. 
Pachnephorus impressus sometimes occurs in some numbers. The 
lifehistory is briefly described and figured in Entomological Note 33. * 
At Hoshangabad Pachnephorus is a serious pest of this crop, the Mr. Ratizam 
beetles feeding on the leaves of the plants. 
Do you practise any control-methods there ? Mr. Fletcher. 
The beetles can easily be collected by shaking the plants. They Mr. Ratiram. 
have the habit of taking shelter amongst fallen leaves, so dry leaves are 
collected and heaped in places and afterwards burnt. 
Tanymecus chloroleucus, Wied., a large grey-white weevil with a green Mr. Fletcher. 
tinge, has been found on Sesamum at Pusa but is not known to be a pest. 
Anomala antiqua was found on Sesamum at Tatkon in Burma, but 
I think it is scarcely a pest. 
Diacrisia obliqua occurs on Sesamum in all districts where this insect 
occurs and may do so in destructive numbers: It is especially bad 
in Bihar and Bengal. Hand-picking of the eggmasses and clusters of 
young caterpillars is the only effective remedy. 
Amsacta moorei seems to replace Diacrisia in Bombay. We have 
already discussed control of this pest. 
Amsacta moorei occurs on young plants in Nadiad. Mr, Jhaveri.
