204 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
GUINEA GRASS (Panicum jumentorum). 
Guinea grass is grown as a fodder crop and its pests are checked 
automatically by frequent cuttings. It is grown to some extent at Pusa 
but we have not had much trouble with insect pests. 
The larvee of Porthesia xanthorrhea are sometimes found in small 
numbers but are scarcely pests. 
Dasychira securis also is found in small numbers at times. | 
Dasychira securis has occurred on Guinea grass at Coimbatore but 
not as a serious pest. 
Sesamoa inferens also has been reared from larve boring in the stems 
but this only occurs when the grass is allowed to grow tall. When the 
grass is cut regularly for fodder, as is generally done, Sesamia does not 
do any damage. 
BamsBoos (Bambusa and Dendrocalamus spp.) 
Bamboos are mostly grown on a large scale in Forest Areas but are 
also often grown in Agricultural Farms, gardens, etc., and you may be 
called on to treat them for insect pests. 
Bamboo leaves are not attacked by any serious pests in the way of 
caterpillars. Matapa aria is a Hesperiad butterfly common in most 
parts of India, Burma and Ceylon ; the larva rolls bamboo leaves quite 
commonly, but is scarcely a pest. Telicota augias is also recorded as 
rolling bamboo leaves, but is not a pest. Crocidophora ptyophora, a 
Pyraustine Pyralid, has also been reared at Pusa from larve rolling 
bamboo leaves, but it is not a pest. 
The young shoots of bamboos are bored by larve of Fruit-flies of 
the genus Stictaspis. Stictaspis ceratitina has been reared at Pusa in 
September from purple larve found in bamboo shoots and S. striata 
from larve in Dendrocalamus shoots at Peradeniya. 
The shoots of bamboo are also attacked by the giant weevils of the 
genus Cyrtotrachelus, which are known to occur in Bengal. C. longipes 
is recorded by Stebbing [Forest Coleoptera, p. 440] from the Chittagong 
Mill Tracts and we have it from Lebong, Darjiling District, reared from 
larvee boring growing shoots of bamboo. In the Darjiling District 
C. dux is also found attacking bamboos‘in the same way. 
The pests of bamboos which are most commonly noticed are the 
sucking insects, which sometimes occur in large numbers. Of these we 
may note :— 
Oregma bambuse. 
A Woolly Aphid. 
A Fulgorid bug. 
Scale Insects.
