Comparison of trap designs for use with aggregation pheromone and synthetic co‐attractant in a user‐friendly attract and kill system to control Carpophilus spp. (Coleoptera: Nitidulidae)

Abstract

Three field experiments were conducted in stone fruit orchards in the Goulburn Valley, northern Victoria, Australia to identify a user-friendly trap for use in attract and kill stations for control of Carpophilus spp. (Coleoptera: Nitidulidae). A funnel trap design was compared with two types of delta trap in one experiment and two types of Lucitrap in another experiment. All traps were baited with synthetic co-attractant and synthetic pheromone. The funnel trap was the most effective type of trap tested. The funnel traps caught significantly more beetles than either the delta traps with bio-attractant or delta traps wrapped with insecticide impregnated banana wrap. No difference was observed between catches in either delta trap design. Lucitraps without covers caught significantly more beetles than Lucitraps with covers but funnel traps caught significantly more beetles than either type of Lucitrap. Beetle numbers caught in the funnel traps were three to five times higher than in Lucitrap. The use of funnel traps in attract and kill stations to protect stone fruit crops by suppressing the Carpophilus spp. population gave superior control to 'grower normal practice of spraying insecticides' both in terms of Carpophilus spp. numbers and in terms of reduction in percentage of fruit damaged.

A host‐plant‐derived volatile blend to attract the apple blossom weevil Anthonomus pomorum – the essential volatiles include a repellent constituent

“…In the codling moth Cydia pomonella L., a devastating pest of rosacean fruits and walnut, volatiles derived from ripening apple enhanced the attraction of males to the female‐produced sex pheromone codlemone . In the Australian sap beetle Carpophilus davidsoni Dobson, fruit‐derived olfactory cues were combined with the aggregation pheromone to attract both males and females …”

“…1 In the Australian sap beetle Carpophilus davidsoni Dobson, fruit-derived olfactory cues were combined with the aggregation pheromone to attract both males and females. 2,3 In the apple blossom weevil Anthonomus pomorum L., a devastating univoltine early-season pest mainly of apple Malus domestica Borkh., pheromones are yet unknown, 4 in contrast to host-emitted attractive plant volatiles. 5,6 So far, an experimental shelter trap affixed to the tree trunk has been developed for monitoring, exploiting the weevil's thermal preference.…”

The role of carbon dioxide as an orientation cue for western corn rootworm larvae within the maize root system: implications for an attract‐and‐kill approach

“…13 Chemical control of WCR larvae with soil insecticides, such as granules 14 or seed treatment, 15 is regarded as the main economic control option in regions of Europe with maize monocultures. 16 Targeting pests with a cryptic life stage, such as root herbivores in the soil, is difficult, making control measures ineffective 17 and causing higher insecticide application rates than for above-ground pests. 18 A combination of an attractant, mimicking host plant cues, and a toxic compound, known as an attract and kill, has been shown to improve the efficacy of insecticide applications compared with other control methods.…”

Attractants for the Green June Beetle (Coleoptera: Scarabaeidae)

“…These traps removed as many as 115,270 fruit feeding beetles, Carpophilus spp., per 10ha stone fruit block during the early attack period. This trapping reduced fruit damage to a level less than that obtained by a growerÕs typical use of insecticide sprays for pest management (Hossain 2006, Hossain et al 2007). …”

“…In contrast, nitidulid species Carpophilus davidsoni Dobson (Bartelt and Hossain 2006), Carpophilus humeralis (F.) (Nout and Bartelt 1998), and Carpophilus lugubris Murray Phelan 1991, Lin et al 1992) were found to be more attracted to a combination lure of an aggregation pheromone and a lure of a synthetic blend resembling the fermenting food lure than to the fermenting food lure alone. Hossain et al (2007) suppressed Carpophilus spp. beetles attacking ripe stone fruits in Australia by placing several funnel traps up wind of the stone fruit block that were baited with a synthetic fermenting food blend (nitidulid blend described by Bartelt and Hossain 2006), a synthetic aggregation pheromone for Carpophilus spp.…”
