certain districts. Where this was not possible, prompt spraying with 

 fish-oil or resin soap was resorted to and the fungi, Cephalosporium 

 lecanii and Emjpusa lecanii, were propagated in places where they 

 did not already occur by tying up fungus-attacked scales in the trees. 

 Ants, especially Cremastogaster, are largely responsible for the spread 

 of these scales, for which reason their nests should be destroyed. 



Pseudococcus (Dactylopius) citri was very destructive in the past 

 to the roots of young plants, but is now successfully kept in check 

 by a soil disinfectant consisting of naphthaline and crude carbolic acid.

A Microlepidopteron, Nephantis serinopa, Meyr., is reported to 

 have caused great injury to coconut palms in Travancore since the 

 beginning of 1917, although the damage was not definitely attributed 

 to it until May 1918. During that tune about 9,000 j)alms have 

 been attacked. The affected trees have a faded appearance and 

 take about a year to recover their normal condition ; if the injury 

 is great, it not infrequently causes the death of the palm. The 

 whole life-cycle is completed on the food-plant. The larvae miue 

 the under-siu-face of the leaf and eat away the green tissue of the leaf 

 blade. Pupation occurs in the damaged leaves. Larvae may be 

 found at all times of the year. 



Spraying with contact and stomach poisons is of value in the case 

 of yoimg trees, but cutting and burning the affected leaves is recom- 

 mended as the best means of keeping the pest in check.
