case a whole branch may be killed. The eggs of the bug are placed in 

 pimctures in young twigs. Usually two are found together ; about 

 50 eggs are laid by a single female under natural conditions. Eggs 

 deposited on 6th April 1915 took six days to hatch. The young nymph 

 sucks the sap from the shoot, and where the proboscis pierces the bark, 

 the young tissues in the neighbourhood are killed and a discoloured 

 patch formed. A poisonous secretion is probably injected into the 

 tissues through the proboscis, since the damage done to the shoots 

 is out of proportion either to the size of the bugs or to their numbers. 

 At Coimbatore, mahogany and guava are also attacked to a slight 

 extent. In Ceylon, this insect has been recorded on tea, cacao and 

 chinchona. The leaves of nim trees are shed at the beginning of 

 March and the new shoots in April are attacked by a second generation 

 of bugs. No further injury occurs until October. 



As a remedial measure, spraying with a contact poison is useful 

 against the nymphs attacking small trees. The spray should be applied 

 as soon as the first cases of wdlt are noticed. In the case of large trees, 

 the cost of spraying would render the treatment prohibitive,

 Psylla pyricola, Forst. (pear psylla) was present in various locahties. 

 The hibernation of this insect may be prevented by scraping all rough 

 bark from the trunks and larger branches. During warm periods in 

 November and December, adults which emerge from shelter may be 

 destroyed by a nicotine spray. In badly infested orchards, autumn 

 spraying, delayed winter sprapng with lime-sulphur and again when
