“…biproruli has only been recorded parasitising B. bibax (Boucek, 1988) and both appear well adapted for survival in inland south-eastern Australia which is characterised by hot, dry summers and cool-mild winters (James, 1990b). James (1992b) suggested an assemblage of natural enemies comprised of both generalists and specialists offered the best prospects for sustainable biological control of B. bibax.

The effect of temperature on the rate of development of Anastatus biproruli (Girault) was determined by rearing individuals on eggs of Biprorulus bibaxBreddin under a range of constant temperatures (17.5-40.0 *C). Rate of development changed in a linear fashion from 17.5-35.0 *C and the lower developmental threshold was estimated to be 12.8 ~ An estimated 331.8 degree days were required for development. Survival of developing parasitoids was optimal (72-90 %) between 25-35 ~ Longevity of virgin adults ranged from 12-26 days at 22.5-35 *C but was only 3.6 days at 37.5 *C. Mated females produced a mean of 54.6 progeny during an average lifespan of 36.4 days at 30 ~ Progeny were produced only during the first 21 days of adulthood but post-reproductive females still attacked and killed hosts. Female A. biproruli overwintered successfully, and were able to parasitise host eggs if direct sunlight was available. A. biproruli also overwintered as imma'.ure stages in host eggs. The biology of A. biproruli is discussed with regard to its importance as a natural enemy of B. bibax. KEY-WORDS : development, longevity, fecundity, overwintering. of the impact of egg parasitoids. Some biological/ecological information has been obtained for Trissolcus oenone (Dodd) (= Trissolcus biproruli) (James, 1988;James & Warren, 1991), the predominant egg parasitoid of B. bibax, but not for other species of the complex.This study presents data on development, fecundity, longevity and overwintering of A. biproruli. MATERIALS AND METHODSA. biproruli used in this study were obtained from labor~tory cultures established from parasitised B. bibax eggs collected in southern New South Wales citrus orchards.

“…In Queensland, P. plagipennis is part of the natural enemy complex that keeps the spined citrus bug, B. bibax (Section 3.1), below the economic threshold level. However, where biocontrol agents do not occur, the citrus bug has become a serious pest (James, 1992). A synthetic lure for P. plagipennis may prove useful in an unusual classical biocontrol program within the country to mass-trap predators in Queensland for establishment in southern regions.…”

A problem for growers attempting to implement integrated pest management programs is the lack of information regarding the compatibility of insecticides with natural enemies. To provide information about this problem, we evaluated the acute and residual effects of 11 commonly used insecticides on nymphs of Pristhesancus plagipennis (Walker) under both laboratory and field conditions. For each insecticide, the length of time that weathering residues caused > 50% mortality was evaluated and compared against the LC50 (acute-toxicity) divided by the recommended field rate. Plots thus combined the acute and residual toxicity of each insecticide. Results suggested that carbaryl, esfenvalerate, endosulfan, and deltamethrin had low residual and acute toxicity to P. plagipennis, whereas chlorpyrifos, methomyl, and monocrotophos were highly toxic at low concentrations and left persistent harmful residues. Cypermethrin, methidathion, malathion, and dimethoate were moderately toxic. The potential use of these insecticides to supplement the control activity of P. plagipennis is discussed.
