“…Several authors reported the control of tephritids by exposing adults to neonicotinoids (Hu et al 1998;Prokopy et al 2000;Stelinski et al 2001 Journal of Plant Protection Research 51 (4), 2011Liburd et al 2004;Scoz et al 2004), but compounds differ in their ability to incapacitate and kill flies (Barry and Polavarapu 2005). The present study was undertaken to compare the performance of neonicotinoids which were used to kill fruit flies under laboratory conditions.…”

Abstarct:The effects of imidacloprid and thiamethoxam against Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann) adults were evaluated under broadcast spray and toxic bait systems in the laboratory. In general, when C. capitata and A. fraterculus were sprayed with insecticides, the time required for killing them was inversely proportional to the neonicotinoid concentrations. By cover spray, females and males of A. fraterculus were more susceptible to imidacloprid and thiamethoxam than C. capitata, presenting significantly lower LT 50 . In the case of imidacloprid bait, no differences at LT 50 were detected between females or males of both fruit flies or between sexes of respective fruit fly species. In general, C. capitata and A. fraterculus adults died in all the toxic baits up to 7 days after application on citrus leaves in the field. The data emphasize the viability of the use of neonicotinoids for the control of fruit flies. Key words: medfly, South American fruit fly, imidacloprid, thiamethoxam, toxic bait INTRODUCTIONThe medfly -Ceratitis capitata (Wiedemann) and South American fruit fly -Anastrepha fraterculus (Wiedemann) were considered the most important fruit fly species (Diptera: Tephritidae) in Brazil in terms of economic importance, due to their large distribution, dominance and number of known hosts. Besides damage to the yield, the incidence of both species provides specific restrictions to export trade fruit to several countries around the world.A wide range of fruits and vegetables are infested by C. capitata and A. fraterculus in Brazil (Zucchi 2000, 2001), including almost all commercial fruits. In the state of São Paulo, both tephritid species have been captured in McPhail traps almost all year long, although with different population peaks.In Brazilian, malathion and others organophosphates have been used in the field against fruit flies over the past 40 years (Sampaio et al. 1966;Orlando and Sampaio 1973;Reis Filho 1994;Salles 1995). Nowadays, five organophosphates, two pyrethroids and spinosad were registered in Brazil for controlling fruit flies (Agrofit 2010). Although the applications are effective in initial fruit fly infestations, the successive sprays of organophosphates and pyrethroids have caused secondary insect and mite pest outbreaks in many Brazilian orchards, like orange (personal information) and pome fruits (Kovaleski et al. 2000). Furthemore, organophosphate applications are restricted (Vargas et al. 2002;Barry and Polavarapu 2004) in many countries. The restrictions make it difficult to manage tephritid populations in fruit crops. Hsu et al. (2004) suggest that Oriental fruit fly Bactrocera dorsalis (Hendel) can develop resistance to various insecticides, including malathion. Cross-resistance between chemicals may also be found for this species. Koren et al. (1984) concluded that medfly females can develop slight resistance to malathion after a nine generation selection process.Although registered insecticides in Brazil are still effective against C. c...

“…Current trends in the search for alternative strategies of fruit fly control include, amongst others, the use of bait stations that serve as population suppression devices (Haniotakis et al, 1991;Hu et al, 2000;Prokopy et al, 2000;Broumas et al, 2002), and the attraction of flies to baited applications of pesticides that must be ingested by the insect (Krasnoff et al, 1994;Mangan, 2000, 2002). The idea behind these approaches is to attract flies from a distance to the devices or pesticide applications, and to halt the flies by stimulating them to feed on the bait.…”

A bioassay to investigate quantitative phagostimulation and ingestion physiology of baits on individual fruit flies is presented. The study was undertaken using two fruit fly species: the Mediterranean fruit fly (Ceratitis capitata), a cosmopolitan insect pest, and the Ethiopian fruit fly (Dacus ciliatus), a quarantine insect in Israel. Our model bait suspension included spinosad as the toxic agent, and 1% yeast hydrolysate with 10% sucrose as phagostimulant. A preliminary toxicology study showed that the two fruit flies are highly sensitive to low concentrations of spinosad baited with this phagostimulant. The maximum concentration needed to kill 90% of the female flies was 4.2 and 8.5 p.p.m. for C. capitata and D. ciliatus, respectively. The bioassay was able to detect the ingestion of low volumes (e.g. 1 ll) of tested solutions. The bioassay was also able to detect differences in intake of different concentrations of spinosad solutions and relate ingestion to fruit fly mortality. Additionally, the bioassay was sensitive enough to highlight differences in intake related to the physiological status of the fruit fly and fly species. The bioassay can also be used to follow ingestion kinetics of baits. We expect that this bioassay will contribute in the exploration of more efficient bait systems for fruit flies.

“…Feeding on spinosad baits resulted in high mortality for Mexican fruit ßies (Prokopy et al 2000), Caribbean fruit ßies (King and Hennessey 1996), and Mediterranean fruit ßies (Vargas et al 2002), although spinosad is not as effective as malathion. Peck and McQuate (2000) showed that bait sprays of either malathion or spinosad resulted in suppression of populations of wild Mediterranean fruit ßies; however, malathion appeared to be more effective.…”

“…However, the use of malathion has been curtailed because of public concern over its actual and perceived negative attributes, spurring the development of alternative toxicants to be used in bait sprays (Dowell 1994, USDA 1999, Prokopy et al 2000.…”

Feeding and Foraging of Wild and Sterile Mediterranean Fruit Flies (Diptera: Tephritidae) in the Presence of Spinosad Bait

The sterile insect technique (SIT) is used to control wild Mediterranean fruit fly introductions in California and Florida in the U.S. In the past, bait sprays containing malathion proved invaluable in treating new outbreaks or large populations before the use of SIT. Recently, a spinosad protein bait spray, GF-120, has been developed as a possible alternative to malathion, the standard insecticide in protein bait sprays. In this study, protein-deficient and protein-fed Vienna-7 (sterile, mass-reared, "male-only" strain) flies and wild males and females were evaluated to determine the effectiveness of the GF-120 protein bait containing spinosad with respect to bait attraction, feeding, and toxicology. There were no effects of diet or fly type on feeding duration in small laboratory cages. Wild flies, however, registered more feeding events than Vienna-7 males. Flies that fed longer on fresh bait died faster. Protein-deficient flies were more active and found the bait more often than protein-fed flies. Data suggest that adding protein to the diet of SIT flies may decrease their response to baits, therefore, reduce mortality, and thus, allow the concurrent use of SIT and bait sprays in a management or eradication program.
