PROCEEDINGS OF THE THIRD EXTOMOLOGICAL MEETING 



I have found an egg-parasite on Idiocerus spp. on mango. 



There are some important mango-growing tracts around Salem, 

 Chittur, and Vizagapatam. These gardens contain trees from fifteen 

 to twenty years old. 



Spraying with fishoil soap has been found effective against this 

 insect. The cost of spraying works out at eight to twelve annas per 

 tree, may be a rupee, but it pays because a tree after treatment yields 

 fruit worth fifteen to twenty rupees. 



It is very important to know when the young nymphs appear, be- 

 cause it is very essential to know the right time to commence spraying. 

 Once we know the time of the emergence of the nymphs we can reduce 

 the number of sprayings to be given to the trees. Spraying is quite 

 effective on yoimg trees but is not so on old ones. Our present difficulty 

 is to secure the spraying machinery. 



The cost you have given seems much too low. Does this include 

 labour charges and hire of machinery ? 



No ; those items are not included. As was explained by me at the 

 last Meeting, the labour is supplied by the watchmen who are maintained 

 by the owners of the gardens to look after the gardens. I have not 

 included cost of the spraying machines either. 



In view of the difficulty experienced by entomologists in India in 

 obtaining sprayers, I may mention that Messrs. Shaw Wallace & Co. 

 are putting on the market sprayers manufactured on the lines of Auto- 

 sprayers. These sprayers are quite good ones, better than the Auto- 

 sprayers, with all the modern improvements, and are quite 

 thirty rupees or so. 



Mr. Speyer is also getting machines made in Colombo. 



Idiocerus sp. 

 This insect was found at Yercaud on orange, 

 far it is a pest. 



It is not known how
