AbstractThe life-history of Dactylopius austrinus De Lotto on the weed Opuntia aurantiaca, is described. The male moults four times and the female twice. The instars are illustrated. Fecundity is shown to be a function of female density on the plant and of host-plant condition. The sexes were produced in a ratio of about two males to one female.

AbstractIn southern Brazil, adults and larvae of the halticine beetle Alagoasa parana Samuelson fed on the foliage and flowers of Lantana tiliaefolia and L. glutinosa (Verbenaceae). The life-cycle of this univoltine species from egg to adult emergence took 80-90 days between October and April. The abundance varied seasonally from four to eight adults per 100 branches. Larvae remained on the foliage during development and pupated in moist, loose, friable soil within a cocoon at the base of the host-plant. Adults overwintered and oviposited in litter at the base of the host-plant. In multiple-choice host- specificity studies in Australia, adults fed lightly on Verbena bonariensis and Clerodendrum speciosissimum (Verbenaceae) and produced minute scars on leaves on unrelated passion fruit (Passiflora edulis) and sunflower (Helianthus annuus). However, A. parana completed immature development only on L. camara among the 55 plants tested. The potential of A. parana as a biological control agent for L. camara in Australia is discussed.

CASST™ herbicide (Alternaria cassiae,) has been shown to be an effective biological control agent for sicklepod ("Cassia obtusifolia LJ, coffee senna ("Cassia occidentalis L.) and showy crotalaria ("Crotalaria spectabilis Roth). Current research has shown the potential of this mycoherbicide for use both alone and integrated with other herbicides as an effective commercial control measure for these troublesome weeds.

The Sericothripinae is a largely tropical group of about 140 species that are often strikingly bicoloured and have complex surface sculpture, but for which the biology is poorly known. Although 15 genera have been described in this subfamily, only three of these are currently recognised, with five new generic synonymies indicated here. In Australia, Sericothrips Haliday is introduced, with one European species deployed as a weed biological control agent. Hydatothrips Karny comprises 43 species worldwide, with six species found in Australia, of which two are shared with Southeast Asia, and four are associated with the native vine genus, Parsonsia. Neohydatothrips John comprises 96 species worldwide, with nine species in Australia, of which one is shared with Southeast Asia and two are presumably introduced from the Americas. Illustrated keys are provided to the three genera and 16 species from Australia, including six new species [Hydatothrips aliceae; H. bhattii; H. williamsi; Neohydatothrips barrowi, N. bellissi, N. katherinae]. One new specific synonym is recognised [Hydatothrips haschemi Girault (=H. palawanensis Kudo)], also four new generic synonyms [Neohydatothrips John (=Faureana Bhatti; Onihothrips Bhatti; Sariathrips Bhatti; Papiliothrips Bhatti); Sericothrips Haliday (=Susserico- thrips Han)].
