62 PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



and vegetable crops, from the Shevaroy Hills where the larvae were very 

 destructive to potato in 1912, and from Gulmarg (Kashmir) from larvae 

 attacking potato tubers ; at Pusa this species has also been reared from 

 larvse found on sugarcane roots and on gram, at Rangpur on tobacco, 

 at Nagpur on clover, and at Lyallpur on beetroot and gram. 



A serious pest of potato in the Hills. Control is difficult, the best 

 remedy being to grub up the larvse which lie hidden by day in the earth 

 around attacked plants. Spraying is not effective in the case of potato 

 as the larvae prefer to feed on the roots and tubers below ground-level. 

 Mr. Ramakrishna At our suggestion one European planter in the Shevaroys tried sliced 



^^^^^- potatoes covered with a mixture of Paris Green and sugar as a bait, 



but it did not prove successful.

• Occurs throughout Northern India and mostly in a belt of about one 



hundred miles wide and parallel with the Himalayas, stragghng as far as 

 Nagpur and Jessore. Also in Ceylon. Not known in Western or 

 Southern India. 



We have examples reared at Pusa on gram, tobacco, groundnut, 

 sweet-potato, celery, cauliflower, cabbage, lucerne and wheat leaves ; 

 at Lyallpur on beetroot, at Shahabad on opium poppy, at Nagpur on 

 clover, at Jabbalpur on potato, at Gaya on gram, at Rangpur on tobacco, 

 and at Jessore on mustard and linseed. 



It occurs regularly every year on the tal lands at Mokameh and has 

 been effectively controlled there by the use of Andres-Maire traps. (See 

 literature cited above.) 

 Mr. H L Dutt ■'■ ^^^^ ^ ^^^ more details to add to the account given at the last 



Meeting. We have found four or five parasites f)f which two or three 

 are Tachinids and two are Braconids. One Braconid is very promising. 

 It appears along with the pest but the parasitization percentage is about 

 five per cent, in the beginning and later it rises to thirty-two per cent. 

 In 1918 it rose so high as seventy-four per cent. The parasitic grub 

 aestivates from March to September. By the middle of September or 

 early in October cocoons kept in the insectary dry up and we cannot get 

 the parasites out of these. Those that remain in the field get submerged 

 during flood time and remain under water in some cases for a couple of
