PRCCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 59 
At Pusa the sweet-pea Aphid is attacked by a fungus (Entomo- Mr, G. R. Dutt. 
phthora) which exercises some check on the Aphid. 
Cow-PEA (Vigna catjanq). 
Cow-pea seedlings are attacked by the larva of an Agromyza, which is Mr. Fletcher. 
described and figured in “ South Indian Insects > (pasos, tes alten It 
is a serious pest of young plants and was bad at Pusa in August 1915. 
At Sabour the maggots were found high up in the stem of cow-peas. Mr. H. L. Dutt. 
At Pusa they are found just near or below the soil-surface. Mr. Ghosh. 
It may be that more than one species is concerned. As regards Mr. Fletcher. 
control, in either case, I do not think that we can suggest anything 
at present. 
A good many insects attack the leaves of cow=pea :— 
Laphygma exigua. 
Azazia rubricans. 
Prodenia litura. 
Plusia orichalcea. 
Colemania sphenarioides. 
Pogria signata. 
Epilachna spp. 
Laphygma exigua is a sporadic pest in most localities. Control is 
difficult owing to the short lifehistory and consequent rapid rate of 
increase and also to the wide range of food-plants. It is possible that 
control may be possible with Andres-Maire traps or on similar lines 
but experiments are required. 
Acazia rubricans is a minor sporadic pest of cow-pea, as of other 
pulses, in Bihar and Madras. 
Prodenia litura is sometimes found on cow-pea but is hardly a regular 
pest of this crop. 
Plusia orichalcea is also an occasional minor pest. 
Colemania sphenarioides attacks cow-pea together with other crops 
in Bellary and Mysore but is principally a pest of cereals. 
Pogria signata is a Chrysomelid beetle which seems to occur as a 
pest of cow-pea principally in Assam. In September 1913 it was re- 
ported to have completely destroyed about four bighas of cow-peas 
erown for seed. We have examples from Pusa and the Nilgiris also, 
so that it is evidently widely-distributed and may turn out to be a 
sporadic pest. 
Epilachna spp. also occur on cow-pea at Pusa but do not do much 
damage as a rule.
