114 Indian Forest Records. [Vol. VIII 
3. Definition of the limiting and optimum conditions for the 
insect, especially temperature, moisture, and altitude ; the relation 
between this optimum and that for different food-plants. 
(b) Genetics. 
4. The course of development of eggs and young ; variations 
in fertility, and influence on fertility of different food-plants and 
climatic or other conditions. 
5. Selective breeding, and the extent to which yield and 
quality may be improved by the distribution of pedigree stock. 
6. The possibility of three-brooded varieties and the extension 
of their cultivation (with special reference to the introduction of 
crop cultivation, for which a three-brooded variety would be very 
suitable). 
7. If the existence of a three-brooded variety is confirmed, 
or other definite varieties exist, the possibility of hybridizing or 
crossing varieties on Mendelian lines for the creation of new forms 
of greater productivity, fertility, or hardiness. 
(c) General Physiological. 
8. In connection with hybridizing, the invention of methods 
for rearing insects individually under observation. 
9. Invention of any methods for rearing insects on a more 
intensive and concentrated scale as is done, for instance, with silk¬ 
worms. 
10. Study of the reactions leading to swarming and to fixation 
(i.e., variations in “ heliotropism, ” “ chemotropism,” etc., in the 
insect’s early stages). 
11. Definition of the qualities or characteristics which determine 
the insect’s preference for particular food-plants or which render a 
plant suitable for its food ; determination of the qualities or charac¬ 
teristics which render it unsuitable. 
(d) Physiology of Lac Production. 
12. The structure of the lac-secreting glands. 
13. The course of development of the glands in the life of 
both sexes. 
14. The products secreted by the different glands, and the 
variation in these products (if any) with the age of the insect.
