PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 231 
Guava (Psidium quyava). 
The leaves of guava are rather free from attack by leaf-eating pests. 
A few weevils occur, of which Myllocerus discolor, M. sabulosus and 
M. 11-pustulatus have been noticed at Pusa and M. viridanus at Palur, 
but they are of no great importance. 
Insects boring in the stem of guava trees include :— 
Arbela tetraonis. 
Belionota prasina. 
Arbela tetraonis has already been considered under Citrus. It is a 
fairly frequent pest of guava also, and control is similar. 
Arbela is a common pest of guava in Gujarat. For control the Mr, Jhaveri. 
larval webbings on the trunk are removed and a wad of cotton mois- 
tened with carbon bisulphide is thrust into the larval gallery ; this 
treatment is quite effective. An injection of kerosine oil was also tried 
in some cases but found not quite so effective ; the kerosine oil did not 
injure the trees. 
Belionota prasina is also found boring in guava trees. It used to Mr. Fletcher. 
be fairly common in Pusa but does not seem to occur so frequently 
nowadays. The beetles appear at Pusa about August-September. It 
is known to occur in mango also and probably has a fairly wide range 
of foodplants. 
Guava fruits are attacked by :— 
Virachola isocrates. 
Dichocrocis punctiferals. 
Chetodacus ferrugineus. 
Virachola isocrates and Dichocrocis punctiferalis are found, although 
rarely, boring in the fruits and are not pests of guava. 
Chetodacus ferrugineus in its various forms has been bred from 
guava fruits but is not very common as a rule and scarcely a pest. 
The sucking insects found on guava are all Scales and some are 
serious pests. 
Monophlebus stebbingi octocaudatus. 
Pulvinaria psidit. 
Coccus viridis. 
Saissetia (Lecanium) hemispherica. 
Chrysomphalus (Aspidiotus) rossi. 
Aspidiotus latanie. 
Monophlebus stebbingi octocaudatus is common on guava, as on most 
trees, at Pusa and probably throughout Northern India. We discussed 
control under mango.
