Monitoring oriental fruit moth (Lepidoptera: Tortricidae) with sticky traps baited with terpinyl acetate and sex pheromone

Abstract

Fuentes-Contreras, E (Fuentes-Contreras, E.)Barros-Parada, W (Barros-Parada, W.)[ 2 ] ; Basoalto, E (Basoalto, E.). Univ Talca, Fac Ciencias Agr, Casilla, Talca, ChileStudies in Argentina and Chile during 20102011 evaluated a new trap (Ajar) for monitoring the oriental fruit moth, Grapholita molesta (Busck). The Ajar trap was delta-shaped with a jar filled with a terpinyl acetate plus brown sugar bait attached to the bottom centre of the trap. The screened lid of the jar was inserted inside the trap, and moths were caught on a sticky insert surrounding the lid. The Ajar trap was evaluated with and without the addition of a sex pheromone lure and compared with delta traps left unbaited or baited with a sex pheromone lure and a bucket trap filled with the same liquid bait. Studies were conducted in a sex pheromone-treated orchard in Argentina and an untreated orchard in Chile. In Chile, the Ajar trap without the sex pheromone lure caught significantly fewer males, females and total moths than the bucket trap, and fewer males and more females than the sex pheromone-baited delta trap. Total moth catch did not differ between the Ajar trap without a sex pheromone lure and the sex pheromone-baited trap. Adding a sex pheromone lure to the Ajar trap significantly increased total moth catches to levels not different from those in the bucket trap. However, the Ajar trap with the sex pheromone lure caught significantly more males and fewer females than the bucket trap. In Argentina, the Ajar trap with or without the addition of a sex pheromone lure caught similar numbers of both sexes and total moths as the bucket trap. The sex pheromone-baited delta trap caught <4% of the number of moths as these three traps. The bucket trap in both studies caught significantly more non-targets than the delta and Ajar traps. Moth catches in the Ajar trap declined significantly after 23weeks when the bait was not replaced

Assessment of SPLAT formulations to control Grapholita molesta (Lepidoptera: Tortricidae) in a Brazilian apple orchard

“…However, these sex pheromone-baited traps are ineffective in tracking pest populations under these conditions since they do not provide information about the presence of females in orchards, as well as whether the females have been fertilized (Cichon et al, 2012). In future studies, virgin females (Stelinski et al, 2007) and food-bait traps (Cichon et al, 2012) should be used to obtain more reliable information about the efficiency of mating disruption using sex pheromone formulations to control G. molesta.…”

Improved monitoring of oriental fruit moth (Lepidoptera: Tortricidae) with terpinyl acetate plus acetic acid membrane lures

“…Work reported by our research group over the past 5 years has detailed new combination lures, including sex pheromones and host plant and microbial volatiles that can monitor both sexes in orchards treated with sex pheromones for mating disruption (Cichon et al., ; Knight et al., ; Knight, Cichon, et al., ; Knight, Barros‐Parada, et al., ). One prerequisite included in our development of new, low‐cost monitoring tools has been the manager’s ability to use any new lures in standard traps with removable sticky liners (Cichon et al., ). Development of the Ajar trap was an intermediate step that allowed bisexual monitoring using sticky liners with catches comparable to the bucket traps but with fewer nontargets to sort, but was still a cumbersome design due to the replacement of the liquid baits (Knight et al., ; Knight, Cichon, et al., ; Padilha et al., ).…”

DA-combo lure and food attractant containing 350 mL of 0.05% terpinyl acetate plus 10% brown sugar solution (Cichon et al, 2013). The DA-combo lure is composed of pear ester kairomone, ethyl (E,Z)-2,4-decadienoate, and codling moth pheromone, (E,E)-8,10-dodecadien-1-ol.…”

“…The DA-combo lure is composed of pear ester kairomone, ethyl (E,Z)-2,4-decadienoate, and codling moth pheromone, (E,E)-8,10-dodecadien-1-ol. A complete description of the terpinyl acetate bait trap is given in Cichon et al (2013). Traps were hung at 50 m apart in the upper third of the canopy, and the liquid solution was changed once a week.…”
