2G2 PEOCEEDINGS OF THE THIRD EKTOMOLOGICAL MEETING 



Control was discussed at the Second Entomological Meeting. 



Oxymrenus hyubris, Mots. 



Dist., F. I. Rhyn., II, 44. 

 We have this from Peradeniya where it occurred in April 1914 on 

 Hibiscus saMariffa in numbers. Distant states that it attacks cotton 

 in Ceylon. 



Aphanus sordidus, Fb. 



Dist., F. I. Rhyn., II, 79-80, f. 62 ; S. Ind. Ins., p. 483; f. 368 ; 

 Proc. Second Eutl. Meeting, pp. 85, 93. 



We have this from Jallandhar, on tobacco, bonga [?]; Palamau ; 

 Pusa ; Ranchi ; Belgaum ; Palur, on threshing floor (groundnut) ; Surat ; 

 Poena, on groundnut, Sesamum indicum ; Taungtha (Burma), stored 

 Sesamum and groundnut ; and Bezwada, on cumbu seeds (threshing 

 floor). 



This insect is sometimes a serious pest of Sesamum and groundnut 

 by carrying ofi the seeds in large numbers from the threshing-floor. 

 It hardly seems to be a pest in the field, although it has been noted to 

 feed on groundnut pods -on the ground when the soil is cracked. The 

 bugs are easily swept up and destroyed. 



I have found these bugs on Cambodia cotton seed on the threshing 

 floor after harvest. 



Pyrrhocorid^. 

 Dysdercus cingulatus, Fb. 



Dist., F. I. Rhyn., II, 118-119, f. 87 ; S. Ind. Ins., p. 484, t. 46 ; 

 Proc. Second Entl. Meeting, pp. 115, 124, 126-130, 132. 

 This species occurs abundantly throughout the Plains of India, 

 Burma, and Ceylon on cotton. Hibiscus esculentus, H. cannabinus, 

 H. abelmoschus, H. rosa-sinensis, hollyhock, Abutilon indicum, Bombax 

 malabancum, Thespesia populnea, etc. At times it occurs in masses 

 of individuals and at such times the bugs are sometimes predaceous 

 on one another, newly-moulted individuals being attacked and sucked 

 by the others. It is a bad pest when it occurs on plants in any numbers. 

 It may be controlled by collection by hand or in bags provided with 

 tin funnels or by attraction to heaps of moistened cotton-seed placed 

 amongst the plants or hung up on the bushes.
