“…We note, however, that the sex-attractant blend used by P. hylaeiformis is the same blend that maximally attracts the strawberry crown moth, Synanthedon bibionipennis (Boisduval) (Lepidoptera: Sesiidae) (Nielsen et al . 1978). Synanthedon bibionipennis is a North American species with which P. hylaeiformis has likely had no contact, but the distribution and seasonal phenology of the former species partially overlaps that of P. marginata (Eichlin and Duckworth 1988).…”

Identification of a sex pheromone component for Pennisetia marginata (Lepidoptera: Sesiidae)

et al. 2012

Raspberry crown borer, Pennisetia marginata (Harris) (Lepidoptera: Sesiidae), is a native North American species and pest of many cane fruits. Using coupled gas chromatographicelectroantennographic detection analyses (GC-EAD) we identified candidate sex pheromone components in pheromone gland extracts and effluvia from calling females. Analysis of gland extracts on a Zebron-5 column revealed four components (A, B, C, and D) that elicited strong responses from male antennae. The two most EAD-active components A and B were hypothesised to be (3E,13Z)octadecadienal [(3E,13Z)-18:Ald] and (3E,13Z)-octadecadienol [(3E,13Z)-18:OH], respectively. Their retention times on other GC columns matched those of authentic standards, thus supporting structural assignments. Synthetic (3E,13Z)-18:Ald, and its GC rearrangement product (2E,13Z)-octadecadienal [(2E,13Z)-18:Ald; component C], also induced antennal responses in GC-EAD analyses of female effluvia. Compounds D in pheromone gland extract, and E and F in female effluvia, elicited EAD responses but could not be identified. In field trapping experiments, (3E,13Z)-18:Ald was the only component that attracted male P. marginata when tested alone. Attractiveness of (3E,13Z)-18:Ald was reduced when combined in binary or ternary blends with any of the other identified components, suggesting one or all may act as pheromone antagonists. In Aldergrove, British Columbia, Canada, peak diel attraction of male P. marginata to (3E,13Z)-18:Ald occurred between 16:00 and 18:00 hours Pacific Daylight Time, at temperatures of 21-238C, We conclude that (3E,13Z)-18:Ald is the major pheromone component of P. marginata.

“…Although pheromones have not yet been isolated from ovipositors of the Douglas-fir or sequoia pitch moths , the compound (Z,Z)-3, 13-octadecad ienyl acetate was found to be attractive to male Douglas-fir pitch moths Duckworth 1988, John son 1993) , and the corresponding alcohol was found to be the most effective trap bait for male sequoia pitch moths (Nielsen et al 1978). Male sesiids are relatively active flyers, and can detect pheromone from a di stance of at least 0.8 km (Niel sen 1 978).…”

“…Because interspecific and intergeneric sex attraction has been observed among the sesiids (Nielsen and Balderston 1973), these compounds and their isomers have since been tested as pheromone attractants for numerous other male sesiid moths , including the sequoia and Douglas-fir pitch moths. (Z,Z)-3, 13-0ctadecadien-1-ol is the most effective trap bait for sequoia pitch moth (Nielsen et al 1978), and its corresponding acetate is effective for the Douglas-fir pitch moth (Johnson 1993). Blends of (Z,Z)-3,13-octadecadien-1 -ol with its corresponding (E,Z) alcohol , and (Z,Z)…”

“…Insect pheromone-management includes monitoring, mass trapping, and mating disruption. Pheromone-baited traps placed at regular intervals throughout the infested area to monitor insect emergence, changes in population size, and the presence of new infestations have been used successfully for various clearwing moth species (Nielsen 1978). Mass trapping consists of capturing enough male moths in pheromone-baited traps to reduce the male population size sufficiently that mating and numbers of fertilized eggs are reduced (Wong et al 1972).…”

Variation in lodgepole pine susceptibility to pitch moth (lepidoptera: sesiidae and pyralidae) attack at the Prince George tree improvement station

Trees in four lodgepole pine seed orchards and a provenance trial have been severely damaged by pitch moth larvae at the Prince George Tree Improvement Station (PGTIS) in recent years. Pitch moths can significantly weaken these trees, resulting in breakage or reduced cone yield, prompting the need for a management strategy. Field trials were carried out to determine which species of pitch moth were present, and gain insight into their biology, including responses to synthetic pheromones, association with disease, and factors affecting tree susceptibility to pitch moth. The purpose was to Jay the groundwork for future cultural or pheromone-based management strategies.Results from emergence traps, pheromone-baited traps , and damage surveys indicated the two spec ies of pitch moth present at the PGTIS were the Douglas-fir pitch moth (Synanthedon novaroensis), and the western pine moth (Dioryctria cambiicola). The former is more abundant in the seed orchards (22.5 % and 1.4 %of trees were attacked by Douglas-fir pitch moth and western pine moth, respectively), and the latter more abundant in the provenance trial (17.5% and 26.4 %, respectively). Pheromone-based trapping confirmed the ge neric clearwing moth pheromone (Z,Z)-3,13-octadecadienyl acetate to be attractive to Douglas-fir pitch moth males. Based on the catches of 35 males, the flight period of this species in 1996 was June 20 to Aug. 6. The flight period of western pine moth in 1995 was July 12 to Sept. 23, based on the capture of 31 moths in emergence cages. In the seed orchard and provenance trial , several tree factors were identified that related to pitch moth incidence, and which cou ld be used in a management strategy. Both pitch moths generally occurred in association with cankers of stalactiform blister rust (P < 0.05). Orchard surveys indicated that Ill clone, tree size, tree location, and presence of previous attack all significantly contributed to the likelihood of a tree being attacked by Douglas-fir pitch moth (P < 0.05) , while subjective measurements of tree vigour did not (P > 0.05). Likelihood of pitch moth attack was positively related to tree size and presence of previous attack. Primary resin volume did not explain differences in clonal susceptibility to Douglas-fir pitch moth, although there were some significant differences between individual clones.My results indicated that management of pitch moths in the PGTIS seed orchards can be focussed on Douglas-fir pitch moth . Therefore, pheromone-based management techniques may be feasible for this species, but additional research is needed to determine optimal parameters for the use of pheromones. Management aimed at minimizing the incidence of stem rusts would be beneficial, as well as the reduction or elimination of susceptible clones from the orchards.
