Plant Pest Campaigns. — Cypms : Ann. Kept. Director Agric, 1921, 

 Nicosia, 1922, p. 4. 



During 1921 campaigns were conducted against Zygaena ampelophaga, 

 and about 2,650 apple and plum trees were sprayed, as they were 

 attacked by the ermine moth [Hyponomeida]. The potato moth, 

 Phthorimaea operculella (Lita solaneUa) was much reduced in numbers, 

 but measures were again carried out against it on the same lines as 

 in the last three years.

 of 1920 and 1921.— Michigan Agric. E.xpt. Sta., East Lansing,. 

 Spec. Bull. 115, March 1922, 54 pp., 23 figs. [Received 26th Tune 

 1922.] 



The continuation of the work previously noticed [R.A.E., A, ix, 18j 

 is recorded, and the comparative value of dusting and spraying against 

 apple and pear pests during 1920 and 1921 is discussed, no definite 

 conclusion being reached in most cases. Peach tree borer [Aegeria 

 exitiosa, Say] was effectively controlled by para-dichlorobenzene 

 when situated low enough to be properly treated, but those that were 

 high up on the trees escaped. 



Strawberry Plant Inspection discontinued in Florida. — Qtrly. Bull. 

 Florida State PI. Bd., Gainesville, vi, no. 3, April 1922, p. 90. 



The State Plant Board of Florida has repealed the rule requiring 

 the inspection and certification of Florida-grown strawberry plants 

 before movement, though this is still required for strawberry plants 

 coming into Florida from other States.

— Qtrly. Bull. Florida State PI. Bd., Gainesville, vi, no. 3, April 

 1922, pp. 76-87, 2 figs. 



The sweet potato weevil, Cylas formicarius, and the type of injury 

 it causes are described for the purpose of enabhng growers to 

 recognise this pest and report upon its occurrence. An account is 

 given of the eradication work that has been in progress in Florida 

 during recent years. The remedial methods used during 1922 have 

 been practically the same as those previously noticed ^R.A.E., A, 

 X, 281]. 



SiMMONDS (H. W.). A Leaf-destroying Moth of Coconuts in Fiji, 



Agonoxena argaula, Meyr. — Agric. Circ, Fiji Dept. Agric, Suva, 

 iii, no. 1, January-March 1922, pp. 7-8. [Received 26th 

 June 1922.] 



The moth, Agonoxena argaula, Meyr., is a common pest of coconuts 

 throughout Fiji, its injuries probably reducing the yield to a con- 

 siderable extent. The adults can frequently be found lying along the 

 midrib of tlie coconut leaflets during the daytime. Eggs have not 

 been observed, but are probably laid singly, and the young larva 

 feeds under a loose web, which it spins on the lower surface of the leaves, 

 eating awa}-^ patches of the green portion and leaving only the epidermis, 

 which subsequently turns brown. Pupation occurs in a cocoon either 

 along the rib of a leaflet of coconut or of some low plant growing near, 

 or upon a blade of grass, and lasts about ten days. In the case of bred 

 larvae fifty per cent, were parasitised, a Chalcid and a Braconid being 

 concerned. The latter may be a hyperparasite.
