In Cuttack and Balasore Districts in Biliar and Orissa, Pachydiplosis 

 oryzce occurred simultaneously with tlie hoppers and did considerable 

 damage. 



Besides these, Sclicenobius bipunctifer, Cnaplialocrocis medinalis and 

 Chapra matliias were also found more or less in the fields infested by the 

 hoppers. 



Preventive and remedial measures. 

 A number of measures were tried during 1914 and 1915 and of these 

 the following appear worth adopting in cases of future outbreaks of the 

 pests. It was also found that the measures adopted met with varying 

 success depending very much upon the particular proclivities of the people 

 and the local conditions prevailing in a particular tract in the infested 

 area. In some places, oil for the lamps was available and people were 

 willing to set up lantern traps, in others people readily took to bagging 

 the hoppers. In some places the local cultivators, profiting by their 

 previous experience, had put down a greater portion of the iarea culti- 

 vated by them under early maturing varieties, thereby getting a crop 

 whereby to maintain themselves as well as their cattle. In fact, some 

 such innovation in local methods of cultivation was seriously mooted by 

 us in case the pests ran their course for a series of years. But fortunately 

 for the raiyats the pests appeared for two years only and have not been 

 reported as yet from any rice-growing tract in the Central Provinces 

 since 1916. 



1. As far as possible the cultivators should be impressed with the 

 necessity of ploughing up their fields after the crop has been harvested 

 and thereafter to allow the cattle to graze freely in the cultivated areas. 



2. If there have been good rains during March- April, and the rainfall 

 is not heavy during July- August, with a considerable break in the rains 

 in the latter part of August and early September with a spell of hot sunny 

 days, the nurseries as well as places containing green grasses should be 

 bagged either with hand-nets or dhoties turned into bags and lightly 

 sprinkled with kerosine oil. 



3. Considerable pioneer work remains yet to be done, but if from 

 data collected in the areas affected last it is found that the number of 

 hoppers is larger than in normal years, systematic bagging is to be
