“…Female codling moth comprised a high proportion (63%–80%) of total catch with this 4‐component lure in trials conducted throughout the 2018 season. The new 4‐component blend was found to be threefold more attractive compared to a blend composed of N‐butyl sulphide, PE and AA (Landolt et al, ) that has been used effectively to mass trap codling moth (Jaffe et al, ). Ternary blends with one of any of the four components subtracted caught significantly fewer moths than the 4‐component blend.…”

“…Similarly, extensive field testing in North America and South America found no evidence that N‐butyl sulphide increased attraction of PE + AA (Basoalto, Mujica, Cichon, Fuentes‐Contreras, & Barros‐Parada, ). Nevertheless, mass trapping of codling moth with the N‐butyl sulphide plus PE + AA lures using 120 traps ha −1 significantly reduced levels of fruit injury in commercial orchards (Jaffe et al, ). The potential for mass trapping to manage codling moth effectively could be much greater if traps were baited with the 4‐component blend identified here because a much greater number of female moths would be removed.…”

“…Herein, we report on extensive field studies evaluating whether the additions of decanal, linalool and either FurLOX or PyrLOX isomers to known attractive blends can increase the effectiveness of traps for male and female codling moth. The most attractive blend was then compared with a blend combining N‐butyl sulphide with PE + AA which was previously found to double the catch of females in traps compared with PE + AA (Jaffe, Guedot, & Landolt, ; Landolt et al, ).…”

Field studies were conducted to evaluate new kairomone blends in combination with pear ester (E,Z)‐2,4‐ethyl decadienoate (PE) and acetic acid (AA) for their attraction of male and female codling moth, Cydia pomonella (L.), in apple, Malus domestica Borkhausen. The addition of decanal to either AA or PE alone significantly increased total and female moth catches. However, the addition of decanal did not improve the attraction of PE + AA. The addition of either the pyranoid (PyrLOX) or furanoid (FurLOX) linalool oxide but not linalool (LOL) increased moth catches with PE but did not increase catches with PE + AA. Similarly, the addition of PyrLOX plus decanal did not improve PE + AA. The addition of (E)‐4,8‐dimethyl‐1,3,7‐nonatriene (DMNT) to either AA, PE + AA or PE + AA+decanal did not significantly increase moth catches. However, the addition of PyrLOX to traps with PE + AA and DMNT (4‐component lure) significantly increased moth catches compared with PE + AA alone or any of the ternary blends of these volatiles. Females accounted for 60%–80% of the total catch with this 4‐component lure. The 4‐component blend with PyrLOX was a more attractive lure than similar blends that substituted LOL, or a binary blend of LOL and FurLOX for PyrLOX. The 4‐component blend caught nearly fourfold more total and female moths than the purported attractant N‐butyl sulphide when it was used in combination with PE + AA. These results indicate that significant improvements in monitoring, mating disruption and mass trapping of codling moth are possible. Further studies are needed to assess the new attractive blend's effectiveness in combination with sex pheromone lures and to evaluate whether other host plant volatiles can be added or substitute for DMNT or LOX when used in combination with PE + AA.

“…A recent study with mass trapping of codling moth in commercial apple orchards reduced fruit injury 50% using 124 traps/ha serviced every other week all season (Jaffe, Guedot, & Landolt, ). Knight, Mujica, et al, previously showed that a 4‐K lure caught 3.7‐fold more female codling moth than the lure used by Jaffe et al, ( n ‐butyl sulphide + PE +AA), suggesting that the efficacy of mass trapping could be significantly improved with the 4‐K lure and/or the cost of the programme may be reduced with the need for fewer traps.…”

Monitoring adult codling moth, Cydia pomonella (L.), is a crucial component in implementing effective integrated management programmes in apple, Malus domestica Borkhausen. Use of sex pheromone lures to track male populations has been the traditional approach, but their use in orchards treated with sex pheromone for mating disruption (MD) has been problematic. Development of kairomone and kairomonepheromone combination lures has allowed the catch of female moths and has benefited several aspects of codling moth management through improved spray timings and action thresholds. Recently, a new four-component volatile blend (4-K) comprised of pear ester, (E,Z)-2,4-ethyl decadienoate (PE), (E)-11 4,8-dimethyl-1,3,7-nonatriene, all isomers of pyranoid linalool oxide and acetic acid (AA) has been characterized that has increased female moth catch threefold versus any previous blend. Field trapping studies were conducted to compare moth catches in traps baited with 4-K versus the use of sex pheromone, (E,E)-8,10-dodecadien-1-ol (PH) in combination with PE and AA. Trials were conducted in orchards left either untreated, or treated with PH or PH + PE. Traps baited with 4-K and 4-K + PH lures caught significantly more females than traps baited with PH + PE + AA lures. Traps baited with 4-K + PH lures caughtsignificantly more total moths than traps baited with PH + PE + AA lures in all three orchards. Adding a PH lure to traps with the 4-K lure did not affect female catch, but significantly increased male and total moth catches. These studies demonstrate that codling moth can be trapped effectively in apple under MD without the use of sex pheromone lures. The significant increase in female codling moth catch with the 4-K lure suggests that efforts to improve spray timings and action threshold determinations as well as mass trapping might be enhanced with this new lure.

“…Mass trapping techniques have been used to successively suppress the populations of various Lepidoptera pest species [8,[23][24][25]. This is the first study to investigate the field efficacy of mass trapping using sex pheromones for the reduction of both adult and larval male E. grisescens populations.…”

Since the identification of the Ectropis grisescens sex pheromone, no effective control technology based on this pheromone has yet been developed and evaluated. In this study, pheromone proportion and dosage, sustained-release dispensers, and pheromone lure-matched traps were optimized. The mass trapping technology developed with the above optimized parameters was tested in a field trial. The results show that two compounds, (Z,Z,Z)-3,6,9-octadecatriene and (Z,Z)-3,9-cis-6,7-epoxy-octadecadiene, at a ratio of 30:70 and impregnated into rubber septa at 1 mg, were the most attractive to male moths. These compounds provided the best performance when combined with a sticky wing trap. Adult male moth monitoring data showed that there was a lower population density in the trapping plot compared with the control plot, and there was a clear difference during the peak adult occurrence of the first five insect generations in 2017. The effect of mass trapping on the larva population was investigated in 2018; the control efficiency reached 49.27% after trapping of one generation of adults and was further reduced to 67.16% after two successive adult moth generations, compared with the control plot. The results of the present study provide a scientific basis for the establishment of sex pheromone-based integrated pest management strategies.
