Laboratory bioassays and field tests were conducted to compare the effectiveness of the new insecticides, imidacloprid, indoxacarb, pyriproxyfen, spinosad, thiacloprid, and thiamethoxam, against apple maggot. The activity ranking of the compounds in reducing oviposition in laboratory bioassays was: imidacloprid, 95% reduction at 11 ppm > thiamethoxam, 91% and thiacloprid, 89% reduction at 100 ppm > spinosad, 98% reduction at 316 ppm > indoxacarb, 80% reduction at 1000 ppm > pyriproxyfen, 0… 

Effectiveness of Attract-and-Kill Systems Using Methyl Eugenol Incorporated with Neonicotinoid Insecticides Against the Oriental Fruit Fly (Diptera: Tephritidae)

It is suggested that neonicotinoid insecticides could be used as an alternative for broad-spectrum insecticides as toxicants in fly traps and persistence is increased compared with sugarcane fiberboard blocks for carrying poison attractants.

Temperature and food availability effects on spinosad and malathion against Rhagoletis indifferens (Diptera: Tephritidae) in the laboratory

Results imply temperature and food availability could be factors affecting R. indifferens control in cherries, but whether temperature is such a factor depends on the insecticide used.

Comparative Efficacy of Insecticides on Bactrocera tryoni and Zeugodacus cucumis (Diptera: Tephritidae) in Laboratory and Semifield Trials in Fruiting Vegetables

Clothianidin was the only insecticide other than dimethoate to affect adult mortality and the synthetic pyrethroid alpha-cypermethrin was also very effective, particularly in semifield trials, although higher incidence of aphid and whitefly infestation was observed in this treatment compared to others.

Effects of Spinosad, Spinosad Bait, and Chloronicotinyl Insecticides on Mortality and Control of Adult and Larval Western Cherry Fruit Fly (Diptera: Tephritidae)

Overall, results in the laboratory and field show that spinosad and chloronicotinyl insecticides differed significantly in their effectiveness against adults and larvae of R. indifferens but that Spinosad,spinosad bait, and imidacloprid seem to be acceptable substitutes for organophosphate and carbamate insecticides for controlling this fruit fly.

Protection of fruit against infestation by apple maggot and blueberry maggot (Diptera: Tephritidae) using compounds containing spinosad.

Overall, the results demonstrate a high degree of efficacy of baited spinosad formulations against these key pests of temperate fruit and suggest that GF-120 is an arrestant for foraging flies.

Feeding and Survivorship of Blueberry Maggot Flies (Diptera: Tephritidae) on Protein Baits Incorporated with Insecticides

Lab feeding trials evaluated fly survivorship on six insecticides incorporated at 4, 40, and 400 ppm in protein baits and found baits containing deltamethrin resulted in no fly knockdown and always had the lowest mortality of any insecticide treatment.

(Diptera: Tephritidae) from Sweet Cherries with Different Egg and Larval Distributions Using Newer Insecticides'

Results indicate neonicotinoids are toxic to eggs and larvae of R. indifferens and that all are more effective in cherries against eggs than larvae, but imidacloprid and acetamiprid appeared to be the most effective when sprayed on cherries in which eggs were only 19.7% and 53.8%.

Insecticide, sugar, and diet effects on feeding and mortality in Rhagoletis indifferens (Dipt., Tephritidae)

Results suggest that thiamethoxam is comparable tospinosad in its effects on mortality, and that using it with sugar in bait may also have similar results as using spinosad bait or spinosads.

Residual Control and Lethal Concentrations of GF-120 (Spinosad) for Anastrepha spp. (Diptera: Tephritidae)

The results suggest that a spinosad concentration of 72 ppm may effectively control these pests for at least 10 d under field conditions.

Plum Curculio (Coleoptera: Curculionidae) Adult Mortality and Associated Fruit Injury After Exposure to Field-Aged Insecticides on Tart Cherry Branches

Data on the plant— insect—chemistry interactions will support use and management decisions as compounds with acute contact activity are phased out.



Recent Developments in the Insecticidal Control of the Apple Maggot

Chemicals exhibiting a high degree of toxicity to adults of the apple maggot, Rhagoletis pomonella (Walsh), in laboratory tests included Dow M361, Dow ET-14, Dow ET-15, Diazinon®, Pirazinon®,

Toxicity and Residual Effectiveness of Insecticides on Insecticide-Treated Spheres for Controlling Females of Rhagoletis pomonella (Diptera: Tephritidae)

Imidacloprid is a promising safe substitute for dimethoate as a fly killing agent on lure-kill spheres after exposure to artificial rainfall and retreatment with sucrose.

Relationships of foliar azinphosmethyl concentration, exposure time, and mortality for the apple maggot (Diptera: Tephritidae)

The results imply that sufficient protection may be provided by older residues (>14 d) when apple maggot populations are low, and should contribute to the development of a “treat-when-needed” strategy for Apple maggot control.

Effectiveness of Thiamethoxam-Coated Spheres Against Blueberry Maggot Flies (Diptera: Tephritidae)

Comparative data on the effectiveness of thiamethoxam- and imidacloprid-coated spheres is provided and the potential of using pesticide-treated spheres for control of blueberry maggot flies is supported.

Comparative toxicities of some insecticides to the apple maggot.

Field collected flies and strains from Vermont and Quebec were not significantly different in susceptibility than laboratory reared flies, and the blueberry maggot R. mendax Curran and the apple maggot were almost identically susceptible to dimethoate.

Effects of Surface Residues of Azinphosmethyl on Apple Maggot Behavior, Oviposition, and Mortality

Equations were developed to predict AM mortality and oviposition inhibition resulting from different residues of azinphosmethyl on apples to predict insecticide effectiveness.

Development and evaluation of a more efficient monitoring system for apple maggot (Diptera: Tephritidae)

A series of tests done in commercial and research apple ( Malus domestica Borkh.) orchards during 1986-1988 evaluated different trap designs and treatment thresholds for apple maggot, Rhagoletis

Persistence of Foliar Residues of Dimethoate and Azinphosmethyl and Their Toxicity to the Apple Maggot12

Field tests indicated that dimethoate was more toxic than azinphosmethyl to adults of Rhagoletis pomonella caged on sprayed foliage, and the rate of loss was similar for each compound, regardless of formulation used.

Apple Insect and Mite Populations Developing After Discontinuance of Insecticides: 10-Year Record

A little-known pest, the lesser appleworm, Grapholitha prunivora (Walsh), caused severe fruit injury during the last 2 years and was consistently the most damaging pest and infested more than 75% of the fruits each year after the 2nd noninsecticidal season.

Laboratory and Field Tests of Insecticides Against the Apple Maggot

When tested by topical application, the synthetic pyrethroids permethrin and fenvalerate were not as effective as azinphosmethyl in killing adults of Rhagoletis pomonella (Walsh) but were the best treatments in preventing apple maggot tunneling injury.
