{Phviopins) carinatiis (purple mite) and Tarsonemiis translticens (yellow 

 mite). Other pests of tea are Saissetia hemisphaerica, Coccus viridis, 

 the grubs of the cockchafers, Lcpidiola pinguis and Anomala super- 

 fltta, the termite Calofcrmes militaris, Oscinis theae, Hclopeltis 

 antonii, Toxoptera coffeae {Ceylonia theaecola, Buckt.), Zeuzera coffeae, 

 and Gracilaria theivora. 



The pests of rubber are Saissetia hemisphaerica and S. nigra, 

 which are generally checked by the fungus Aschersonia sp., and 

 Batocera riibus. 



Nephantis serinopa is recorded on coconuts.

Agric. Gaz. Canada, Ottawa, viii, no. 2, March-April 1921, 

 pp. 126-127. 

 The value of birds as destroyers of noxious insects is discussed, 

 and the observations of many authors on this subject are quoted. 



Sanders (G. E.). Spraying versus Dusting. — Agric. Gaz. Canada, 

 Ottawa, viii, no. 2, March-April 1921, pp. 134-136. 

 The advantages and disadvantages of dusting are enumerated. 

 Recent experiments show that dusting is cheaper and is just as efficient 

 in the control of fungous diseases and biting insects as spraying, 

 but the latter is superior in the control of sucking insects, such as 

 Psylla sp. and green apple bug {Lygns communis).

Removal and destruction of affected plants has been shown to be 

 a successful remedy against the moth borers, Schocnohius incertcllus 

 (hipiinctifer) and Chilo simplex in rice. Spodoptera mauritia causes 

 serious damage to punja rice, and may be destroyed by the applica- 

 tion of lime and ashes in equal proportions, or Paris green and 

 lime 1 : 80, especially when the larvae are very young. Bagging 

 with hand nets is the only successful remedial measure against the 

 rice bug {Leptocorisa varicornis). 



Nephantis serinopa (coconut leaf-roller) was the most important 

 pest of coconut palms dealt with during the year. The attacked 

 leaves should be cut off and burnt. Regulations have now been 

 passed for the eradication of this pest. Other miscellaneous pests 

 recorded are the rhinoceros beetle (Orycies rhinoceros), the rice Hispid 

 and a mealy-bug {Pseudococcus sp.).

The usual insect pests were dealt with during the year, but no 

 special investigations were undertaken. The most important coffee 

 pests were the berr}^ borer [Stsphanoderes hampei], variegated bug 

 [Antestia lineaticollis], thrips, Aphids and root scale, Pseudococcus 

 citri. No pests of cacao or Para rubber have been recorded during 

 the last seven months, and only stainers [Dysdercus] are recorded 

 on cotton. Enquiries have also been made with reference to termites 

 and the banana borer [Cosmopolites sordidus].
