48 PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



As regards control, the only method that can be suggested is the' 

 selection of resistant varieties. 



Agromyza sp. 



" Cowpea Agromyza ", S. Ind. Ins., p. 358, f. 217, (1914). 

 Agromyza sp., Proc. Second Entl. Meeting, pp. 52, 56, 59, (1917). 



We now come to one or more species of Agromyza, one of which may 

 possibly be A. phaseoli, which bore into the stems of pulse crops. In 

 Ceylon and at Nagpur the larvae have been found in the stems of French 

 beans and considerable damage may be done. At Koilpatti, Coimbatore 

 and Tinnevelly the larva? bore into the stems of young plants of cowpea, 

 lablab and green gram, the plants withering as the result of attack, and 

 pupation taking place in the larval burrow. At Pusa we have a species 

 referred to on pages 62 and 65 of the Proceedings of the Second Entomolo- 

 gical Meeting and possibly distinct from the foregoing, whose larva bores 

 in the stems of peas and exotic field-beans. 



It is quite possible that several distinct species may be concerned. 

 Certainly there seem to be differences of food-plant .and habit. At Pusa, 

 for example, the larvse in peas occur near or below soil-levelj whikt at 

 Sabour they have been noted high up in cowpea stems. So it looks as 

 if we have several species mixed up here but I cannot undertake to 

 differentiate them. 



{Bakla Stem-fiy). 



Proc. Second Entl. Meeting, p. 62, (1917). 



A fly, which may be an Agromyzid, has been reported by Ratiram 

 as attacking stems of Viciafaba in the larval stage in the Chanda District 

 of the Central Provinces, but I have seen no specimens and know no 

 more about it. 



{China stem- fly). 



Proc. Second Entl. Meeting, p. 202, (1917). 



This is another unidentified species found at Pusa, the larva attacking 

 the stem of China {Paspalum miliaceum) before the ear ripens. The 

 effect of attack is like a borer, the ear drying without forming any grain. 

 The affected plants are easily spotted in the field. This fly was first 

 noticed at Pusa in September 1916.
