252 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
JAK (Artocarpus integrifolia). 
The buds and young shoots of jak are attacked by Margaronia (Gly- 
phodes) cesalis, as described in “ South Indian Insects,” p. 435, fig. 311, 
and I have no more to add to that. 
Arbela tetraonis has been noticed boring in the stem at Pusa, but is 
not common on jak and not a regular pest. 
The sucking insects found on jak include :— 
Cosmoscarta relata. 
Ptyelus sp. 
Monophlebus stebbingi octocaudatus. 
Pseudococeus (Dactylopius) sp. 
Cerococcus corymbosus. 
Cosmoscarta relata seems to be confined to Coorg and Mysore, where: 
it is a serious local pest. It is described and figured in ‘“ South Indian 
Insects,” p. 495, fig. 383. 
In Malabar another Cercopid bug, Ptyelus sp., is found on jak shoots. 
Monophlebus stebbingi octocaudatus is abundant on jak at Pusa, often 
clustering thickly on the young shoots and fruits. 
In Malabar a species of Pseudococcus (Dactylopius) is very bad on the 
shoots and tender fruits, and Cerococcus corymbosus also occurs in Mala- 
bar, completely covering the shoots and young leaves and fruits. 
The fruits of jak seem fairly free from pests, other than those we 
have already noticed, but at Pollibetta, in South Coorg, in May 1914 1 
bred Chetodacus ferrugineus incisus in some numbers from larve in ripe 
jak fruits and the rotten fruits lying on the ground also attracted 
Ptecticus rufus and Pt. australis in some numbers; but all these flies 
probably breed only in over-ripe and fallen fruits and thus are not 
pests. 
Breab-FRuir (Artocarpus incisa). 
Bread-fruit is grown to some extent on the West Coast of Southern 
India, but we know nothing of any insect pests. 
I have never seen any insect pests on Bread-fruit. 
Durtan (Durio zibethinus). 
Durian is grown in the South of Burma and at Moulmein is attacked 
by a borer, probably a Longicorn beetle, whose erub bores just below the 
bark. We do not know exactly what the beetle is but the grub can be 
controlled by cutting it out.
