Realistic Data

Effect of age, sex and time exposure of Anastrepha fraterculus (Wied.) to toxicity of fenthion was evaluated. The age of the flies was important to the appearance of the first intoxication symptoms; males and females of reproductive ages (30 and 60 days-old, respectively) were less susceptible to insecticide than flies in the remainder ages (four and 120 days-old). The effect of body weight on insect intoxication was not detected. LT 50 biossay with fenthion (varying from 3-7 minutes) showed a lower susceptibility of males than females at all ages. Adults of both sexes and 30 days-old submitted to continuous and discontinuous exposure to fenthion did not show toxic cumulative effect of the insecticide. The statistical analysis suggests a possible general detoxification mechanism (quantitative and/or qualitative) to fenthion sex-, age- and time-related. Once the species is highly mobile in nature we suggest that in fruit fly toxicological bioassays, these biological traits need to be observed in order to obtain more realistic data.

The Impact

Fruit flies (Family Tephritidae), in particular the Queensland fruit fly (Bactrocera tryoni; QFF), areone of the biggest biosecurity risks for New Zealand horticulture. New Zealand has one of the bestscience-based biosecurity systems in the world, based on years of experience and sound research. Theintroduction of fruit flies to New Zealand is now well managed in commercial fruit imports, but the riskis rising from growing trade and travel and, in the case of QFF, climatic adaptation and spread to moresouthern localities. Smarter solutions are continually needed to manage this increasing risk, and to dealwith such pests when they arrive. We present a brief summary of current and anticipated research aimedat reducing the likelihood of entry into New Zealand and/or minimising the impact for the fruit flyspecies of greatest threat to New Zealand. Research spans risk assessment, pathway risk management,diagnostics, surveillance and eradication.

Horticultural Pest

Abstract B. tryoni, the Queensland fruit fly, is the most costly horticultural pest in Australia and has invaded several countries in the surrounding region (White and Elson-Harris, 1994). It has the potential to spread to many places around the world because of its wide climatic and host range (Meats 1989b; Sutherst et al., 2000) and a tendency to be carried by human travellers at the larval stage inside infested fruit. B. tryoni is a very serious pest of a wide variety of fruits throughout its range. Damage levels can be anything up to 100% of unprotected fruit.

Cuticular Layer

The cuticular layer of the insect exoskeleton contains diverse compounds that serve important biological functions, including the maintenance of homeostasis by protecting against water loss, protection from injury, pathogens and insecticides, and communication. Bactrocera tryoni (Froggatt) is the most destructive pest of fruit production in Australia, yet there are no published accounts of this species’ cuticular chemistry. We here provide a comprehensive description of B. tryoni cuticular chemistry. We used gas chromatography-mass spectrometry to identify and characterize compounds in hexane extracts of B. tryoni adults reared from larvae in naturally infested fruits. The compounds found included spiroacetals, aliphatic amides, saturated/unsaturated and methyl branched C12 to C20 chain esters and C29 to C33 normal and methyl-branched alkanes. The spiroacetals and esters were found to be specific to mature females, while the amides were found in both sexes. Normal and methyl-branched alkanes were qualitatively the same in all age and sex groups but some of the alkanes differed in amounts (as estimated from internal standard-normalized peak areas) between mature males and females, as well as between mature and immature flies. This study provides essential foundations for studies investigating the functions of cuticular chemistry in this economically important species.
