Oriental Fruit Moth' Pheromone Component Emission Rates Measured after Collection
نویسنده
چکیده
We collected and quantified both syntheticand natural Oriental fruit moth [Grapholitha molesia (Busck)] sex pheromone components in 250-1111 round-bottom flasks bv hexane rinsing of compounds adsorbed on the glass walls This simple procedure collected 100% of the pheromone evaporated inside the flask and was useful for quantifying both nanogram and microgram amounts of emitted pheromone Emission rates of ( 2 ) 8dodecenyl acetate from 1000, 100, and 10 pg-loaded rubber septa were 219, 12, and I 2 nglhr, respectively G molesia females emitted this component at 3 2 ng/ hr, close to the emission rate from a 10 pg-loaded septum, which evokes "long-range" and "close-range" behaviors in the male The corresponding alcohol, (2)-8-dodecenyl alcohol, was emitted from rubber septa ca 3 times faster than the acetate Key Words-Oriental fruit moth. Grapholitha molesia, pheromone release rate, airborne collection, (7)-8-dodecenyl acetate, (Z)-8-dodecenyl alcohol

Sprayable microencapsulated sex pheromone formulation for mating disruption of oriental fruit moth (Lepidoptera: Tortricidae) in Australian peach and pear orchards.
Areawide mating disruption treatments have been effective in controlling infestation of oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), in Australian pome and stone fruit orchards. Although successful, the areawide mating disruption program has been an expensive approach by using hand-applied Isomate dispensers. Sprayable microencapsulated (MEC) pheromone formulation...

The efficacy of mating disruption by using Isomate-M 100 pheromone dispensers and two formulations of microencapsulated sprayable pheromone for management of oriental fruit moth, Grapholita molesta (Busck), was compared with conventional insecticides in large plot studies in Henderson County, North Carolina, in 2000 and 2001. In addition, experiments were conducted in small and large plots to t...
متن کاملPheromone release rate determines whether sexual communication of Oriental fruit moth is disrupted competitively vs. noncompetitively
Communicational disruptionmechanisms for Oriental fruit moth,Grapholita molesta (Busck) (Lepidoptera: Tortricidae), were determined using a suite of mathematical tools and graphical operations that enable differentiation between competitive attraction and non-competitive mechanisms of disruption. Research was conducted in 20 field cages, each covering 12 mature apple trees. Commercial monitorin...
متن کاملMale oriental fruit moth response to a combined pheromone-based attracticide formulation targeting both oriental fruit moth and codling moth (Lepidoptera: Tortricidae).
Combined attracticide formulations targeting Oriental fruit moth, Grapholita molesta (Busck), and codling moth, Cydia pomonella (L.), were tested in a field trapping experiment. Capture of male codling moths in traps baited with the combined formulation was reduced compared with traps baited with the codling moth formulation alone, whereas capture of male Oriental fruit moth was increased compa...
متن کاملA pulsed cloud of sex pheromone elicits upwind flight in male moths
Male oriental fruit moths do not fly upwind in a continuous uniform cloud of pheromone, but readily do so when the cloud is pulsed at 1 or 0 51s or when a plume from a point source of pheromone is placed within the continuous cloud It is suggested that males of moth species that require such fluctuating pheromone stimulation for upwind flight will normally receive it from a filamentous, point-s...
