NiCHOLLS (H. IL). Scale Insects. — Tasmania Depf. Agric. <& Stock, 

 Hobart, Bull. 78, 1918, 12 pp., 8 figs. [Received 2nd June 1920.] 



This bulletin gives an account of the various scale-insects that are of 

 economic importance in Tasmania, including Aspidiotus perniciosus 

 (San Jose scale), A. ostrcacfonnis (oyster-shell scale), A. rapar (greedy 

 scale), A. rossi, A. hederae (white scale), Lepidosaphes ulmi (Mytilaspis 

 pomorum) (mussel scale), Aulacaspis rosae (rose scale), Asterolecanium 

 quercicola (oak scale), Ealecanium (Lscanium) persicae and Coccus 

 (L.) liesperidum, while a few others, not of economic importance, are 

 also mentioned. 



Dormant spraying with lime-sulphur is recommended against 

 A. perniciosus and L. idmi, a weaker spray being used if the leaves are 

 out. Lecanium spp. are more resistant to lime-sulphur, but on 

 deciduous fruit trees they can be kept in check by the use of oil sprays 

 such as red oil, crude petroleum or kerosene emulsion. All the 

 insecticides mentioned have been described in a bulletin already 

 noticed [R.A.E., A, vii, 48]. Every effort should be made to prevent 

 the spread of scale-insects. It is an offence under the San Jose 

 Scale Act for anyone to remove any part of an infested tree from the 

 enclosure wherein it is growing without the consent of the Acting- 

 Director of Agriculture. 



Tryon (H.) & Benson (A. H.). The Banana Weevil {Cosmopolites 

 sordida, Chevr.). — Queensland Agric. Jl., Brisbane, xiii, no. 4, 

 April 1920, pp. 165-168, 5 figs. 



Cosmopolites sordidKS (banana weevil) has been present in Queensland 

 for at least 25 years, in spite of stringent regulations passed under the 

 Diseases of Plants Act. Another banana weevil, Metamasius 

 hemipferus, L., has also been imported on banana plants from Jamaica. 

 The life-history and habits of G. sordid us are given, with a description of 

 the various stages. Growers are warned against mistaking any of the 

 several species of Sphenophorid beetles that occur in Queensland for 

 C. sordidus. Every precaution should be taken to ensure that only 

 sound suckers are planted and the usual recommendations are given 

 for the treatment of infested plantations [R.A.E., A, vii, 86, etc.]. 

 The method of destroying infested plants by digging them out and 

 making them into a compost heap with fresh horse manure or chopped 

 green vegetation so that the mass will ferment and generate enough 

 heat to kill the beetles is recommended.
