98 DESTKUCTIVE INSECTS OF VICTORIA : 



pupae of these moths.) As this is such a singular insect, 

 and the printing in our plate is in a few instances hardly 

 correct in the colouring, it was thought necessary to give 

 a fuller description of the insects than we have usually 

 done. 



Prevention and Remedies. 



This pest, although it appears in such vast numbers as 

 often to strip every leaf from a tree, and this in a very 

 short time, may usually be prevented from laying its 

 eggs by means of an occasional spraying with kerosene 

 emulsion, or, better still, kerosene, used by means of the 

 " attachment," as previously mentioned, and as the 

 females especially are easily seen, these can be collected 

 by hand and destroyed. In some countries, viz., in 

 America, the larvae of the Gypsey moth, which some- 

 what resemble the ones under notice, are trapped by 

 placing a bandage known as the " Burlap," which some- 

 what resembles the bands commonly used in trapping the 

 grubs of the codlin moth, but differing from the latter 

 bands in beins; tied rather looselv round the middle, with 

 the upper part partly folded down over the tie, and thus 

 forming a more roomy trap than is required for the larvae 

 of the codlin moth. In Victoria, at least where the pest 

 is, unfortunately, but too common, we can easily keep the 

 caterpillars under control, the use of arsenites being all 

 that is required, as in this case it is better to poison the 

 grubs outright than to use measures for preventing the 

 moths from depositing the eggs. The following, if done 

 occasional^ and properly, will kill any larvae which feed 

 upon the leaves. One pound Paris Green (paste form is 

 the easiest to mix), 6 lbs. lime, slake, strain, and use the 

 "milk," diluted with from 160 to 180 gallons of water, 

 according to the nature of the trees to be treated. It 

 must be borne in mind that the hairy nature of the grubs 

 would probably prevent kerosene, or other materials 

 which usually kill by contact, destroying these cater- 

 pillars, as it would not penetrate to the body of the insect,
