The pupae in the crevices of wood- work, etc., may be killed by passing 

 the flame of a painter's blow-lamp over all suspected corners. The 

 market baskets and strikes should never be allowed in the glass- 

 houses, and these, as well as those used for picking, should be dipped 

 from time to time in boUing water as they frequently contain pupae. 

 All weeds should be removed inside as well as in the neighbourhood 

 of the houses, as this moth thrives better on weeds such as Chenopodium 

 and Polygonum than on tomato leaves only.

 Agric. Jl., Brisbane, xii, no. 4, October 1919, pp. 200-204, 1 plate. 



Most of the injury to peanuts in Queensland is caused by a species 

 of Pseudococcus closely resembling P. trifolii, Forbes, which has been 

 recorded on Trifolium pratense in South America. This mealy bug 

 was found on the roots and underground portions of the plants at a 

 depth of from 1 to 4 inches, as well as on the nuts, where all stages were 

 found simultaneously. The larva and summer female are described 

 and illustrated. 



Other insect pests of this plant are a Pyralid, probably a species of 

 Glyphodes, which feeds on the young shoots in March and of which the 

 pupal stage occupies about 2 weeks ; a Liparid, Laelia sp., larvae 

 of which were found devouring the foliage in February, pupation 

 commencing on 3rd February and the imago emerging 12 days later ; 

 the Noctuids, Heliothis (Chloridea) assiilia, Gn., of which the larvae 

 bore into the ends of the stems, pupation occurring in March and lasting 

 about 2 months, and H. obsoleta on young leaves ; the grasshoppers, 

 Atractomorpha crenaticeps, Blanch., and Cyrtacanthacris sp. ; and a 

 Dynastid beetle, Isodon puncticolle, which cuts the stalks about 2 inches 

 beneath the surface. 



Insects attacking stored peanuts include a Phycitid moth, 

 Homoeosoma vageUa, Z., a Tenebrionid, Triholium ferrugineum, F., 

 and a Nitidulid, Carpophilus sp.

Experiments with soluble arsenic as a means of killing the trees 

 on which sugar-cane beetles [Lepidiota] feed, show that the best results 

 are obtained by ringing them as close to the ground as possible. The 

 cut surfaces of the wound should then be thoroughly wetted with 

 a solution consisting of one pound of arsenic, two pounds of washing 

 soda and one gallon of water. Suckers from old stumps may easily 

 be destroyed by cutting into the live wood and applying a small 

 quantity of the poison. 



Attention is drawn to the continued efficacy of the Agromyzid fly 

 introduced in 1917 from Hawaii for the destruction of the weed 

 Lantana camara.
