64 REPORT OF THE AGRICULTURAL RESEARCH INSTITUTE 



inside cracks and under scales of bark of coffee bushes; they 

 are rarely visible, and very rarely laid externally. Experi- 

 ments were started to ascertain the length of life-cycle, as 

 it has been uncertain whether there are one or two broods in 

 the year. Results will be written up when further inform- 

 ation on these experiments comes to hand. 



Information was also collected on pests of Erythrina 

 lithosperma, which is extensively grown for shade and 

 green-manure on Coffee Estates. 



6. Orchard and Garden Pests. A special study has 

 been made during the last three years of Insect Pests of 

 cultivated Fruits, Vegetables and Flowers, and a consider- 

 able amount of information has been collected on the 

 insects concerned, their identity, life-history, foodplants, 

 occurrence and control. This information will, it is hoped, 

 be issued shortly as a Bulletin. 



Special attention has also been paid to the collection of 

 Fruitflies. A large collection of these was sent to Pro- 

 fessor Mario Bezzi, of Turin, last year but was apparently 

 lost in the S.S. "Persia" on return after identification-, 

 fortunately, the types of eight new species had been sent 

 direct to the British Museum by Prof. Bezzi. Myioparda- 

 lis pardalina, the " Baluchistan Melon Fly," was reared at 

 Pusa from fruits of Cucumis trigonus; it was not hitherto 

 known to occur except in North- Western India. 



An important find during the year was the European 

 Olive Fly (Dacus oleae) in wild olives in the North-West 

 Frontier Province. Its occurrence in India was hitherto 

 unknown and it is likely to be of importance in view of the 

 attempts now being made to introduce the cultivation of the 

 European olive in North- West India and Kashmir. 



7. Life-histories of Insects. In the Insectary were 

 reared about 200 species of insects which had not been 

 reared before. These included about fifty Coleoptera, of 

 various families, of which there was no previous informa- 

 tion regarding their breeding-places and habits. Many 

 interesting facts have been noted in this connection; for 

 example, one Elaterid beetle grub (Agrypnus sp.) has now
