also see 514. 



On the Herbert River Mr. C. E. Lacaze had excellent results 

 in the destruction of grubs, by adding 12 lb. of white arsenic to 

 each cwt. of nieatworks fertiliser used for manuring his cane. 

 Note. — Mr. Lacaze later said that he used about 6 cwt. of the 

 manure per acre, hence about 70 lb. of arsenic.

The pupee of the beetles sometimes at a depth of 4 feet, but 

 the resulting beetles emerge. The grubs eating earth may be 

 killed readily by adding poison to the soil.

Grub. Aust. Sugar Journ. vi, 374.

Journ. vi, 631. 



Green Muscardine fungus from Samoa said to already occur 

 in the Cairns district. Named Metarrhisium anisopliw 

 (Metschnikoff) Sorokin. This fungus found in 1901 on Mr. 

 Blackwell's farm, also at Highleigh ; again, in 1908, at 

 Hambledon. This article summarises information on this 

 important subject.

Aust. Sugar Journ. vii, 343. 



Mr. Jodrell remarked that if the £20,000 spent for grubs and 

 beetles had been used for removing feeding-trees they would have 

 been rid of the grub long ago. Mr. Jarvis stated that the eggs 

 were deposited in soil at a depth of 5-7 inches, and that ploughing 

 would destroy both them and the young grubs.
