PKOCEEDINGS OF THE THIRD EN ruMOLOGlCAL MEETING 1071 



" To this end we recommeud that the coiu'se should iuchide, in 

 addition to the lecture and laboratory work, a sufficient amount of 

 practical work in the field to acquire a knowledge of the insects under 

 field conditions and of the actual methods adopted to control them. 



■' In view of the demand for coloured plates showing the life-histories 

 of Indian insects for the use of their classes of students, we recommend 

 that all Agricultural Colleges requiring such plates should make an 

 annual estimate in anticipation of their demands and that such estimates 

 should be forwarded to Pusa by 1st January in each year to be consoli- 

 dated into one indent in order to reduce cost and expedite delivery of 

 these plates." 



This Report is now before the Meeting. Has anyone any remarks Mr. Fletcher, 

 to make on it ? 



What is the cost of these coloured plates, supposing that we require Mr. D'Abreu, 

 only one copy of each ? 



That is the difficulty which we sought to avoid in the last paragraph Mr. Fletcher, 

 of the Report. It is as much trouble to the printer to get the blocks 

 in register to print off a single copy as it is to print off a thousand, and 

 he would probably charge you at least one rupee each for single copies. 

 If we can know the demand, we can get a number printed at one time. 



The lines suggested by the Committee seem to meet the requirements. Mr. Ghosh. 



In the Agricultural Colleges the aim is to train farmers and fruit- 

 growers and not entomologists. We want to give these students a 

 training which will be of real practical value to them, for example, they 

 should be able to distinguish a pest from a non-pest ; any insect biting 

 off a few leaves does not become a pest. If the student cannot make 

 a distinction in this direction he is likely to magnify small things and 

 to adopt preventive and remedial measiu-es which are not at all called 

 for. 



Secondly, they should be able, at least in all ordinary cases, to trace 

 the real culprit when they observe any injury to their crop or orchard ; 

 for instance, when they see the top-shoot of a brinjal plant droop they 

 should have sufficient knowledge to see that the ladybird-beetle grub 

 feeding on the Aphids on the leaves is not responsible for it. 



Thirdly, they should be able to distinguish the beneficial from the • 

 injurious. 



Fourthly, they shoidd have just a general knowledge of the external 

 anatomy of insects so as to be able to place the insects at least in then: 

 Orders. This amount of systematic work is (piite sufficient for them. 



In order to make them familiar with common insects, their mode 

 of feeding and causing damage, merely telling them of these insects or 

 giving a description of their damage, however elaborate the description
