GENEKAL CONCLUSIONS 45 



Although the difficulties were many and the conditions 

 were unfavorable, the results leave no doubt that bagging 

 can be done effectively. The cost is comparatively small, 

 for each raiyat will be able to look after his land with the 

 help of his own family. As the infestation last year was 

 comparatively light, the numbers of grasshoppers caught 

 cannot be taken as a gauge of the effectiveness of bag- 

 ging. In Anavatti village, where bagging was carried on 

 most thoroughly, the hoppers were reduced to such small 

 numbers that practically no damage was done to the 

 crops, while in the other villages bagged, the losses this year 

 were slight. We are quite satisfied that a thorough bagging 

 on the bunds begun about the first or second week in 

 July followed by a second one also on the bunds after an 

 interval of ten or fifteen days, and, in badly infested areas, 

 a third one about the beginning of August, will prove an 

 effective check to the ravages of this pest.^ It is, however, 

 absolutely essential that all the raiyats in an infested vil- 

 lage co-operate ; otherwise, the efforts of those who do take 

 up the work will in all probability fail. 



SUMMARY OF RESULTS. 



1. The Eice Grasshopper while found widespread 

 over Mysore has, as yet, proved a serious pest only in a 

 few isolated localities. However, as it is capable of doing 

 immense damage to sugar-cane as well as to paddy when 

 it is present in large numbers, a knowledge of its life- history 

 and of means of combating it should be acquired by all 

 those interested in paddy and sugar-cane cultivation. 



2. The grasshoppers hatch out about the middle of 

 June from masses of eggs laid the previous autumn. 



3. The developing hoppers pass through six (males) 

 or seven (females) stages or instars in their develop- 

 ment. They take, in all, from two and a-half to three and 

 a-half months for growth. 



4. The full-grown grasshoppers are provided with 

 wings and can fly short distances. They do not, however, 

 move from one locality to another by flight as do the 

 migratory species. Their spread is therefore likely to be 

 comparatively slow. 



5. During a considerable portion of their development,
