Variation in horn and body size of both sexes of Xylotrupes gideon australicus is normally distributed with no evidence of dimorphism in either sex. This contrasts with that of X. gideon gideon, in which males are dimorphic for horn length, but horn

In this study, the question of whether Childers canegrub, Antitrogus parvulus (Britton) overwinters in the subsoil was addressed. Irrigated fields of sugarcane were sampled during a 2-year period near Bundaberg in southern Queensland. Antitrogus parv

Summary The degree of localization in the distribution of Australian scarabaeine (320 spp.), aphodiine (160 spp.), geotrupid (166 spp.) and dynastine (182 spp.) scarabs is analysed. Localization differs among these groups, appearing to increase margi

The responses of 24 commercial cultivars and 1 experimental clone of sugarcane to the margarodid Eumargarodes laingi Jakubski were evaluated over the plant and 3 ratoon crops of a field trial in southern Queensland. Clones varied in the number of cys

Snowdrop and wheatgerm lectins were found to be insecticidal and growth inhibiting dietary proteins for larvae of the sugarcane whitegrub Antitrogus parvulus. At concentrations as low as 0.5 mg of snowdrop lectin per gram of semi-artificial diet, gro

The activity of proteins from two New Zealand strains of Bacillus thuringiensis, DSIR517 and DSIRl246, was determined against the Australian canegrub Antitrogus consanguineus. Two DIG-labelled crystal proteins from strain DSIR1246 and three from stra

Current management options to minimize the impact of canegrubs (larvae of melolonthine scarabs) on Australian sugarcane are heavily dependent on the use of synthetic insecticides. In developing a successful integrated pest management (IPM) programme

Sampling statistics were determined for adults of the froghopper Eoscarta carnifex (F.) and associated symptoms on sugarcane crops in northern Queensland, Australia. Samples using 10 consecutive stems per sampling unit minimized the variance: mean ra

Of four diets tested, one based on lima beans and casein was selected as the best and easiest for rearing third instars of Japanse beetles, Popillia japonica Newman. The diet gave the best survival and heaviest pupae and was previously used for reari
