“…Male behaviors included antennation, upwind flight, and courtship behavior that involved abdominal flexing accompanied by substrate vibration (Staples 1999). These responses were similar to laboratory and field data from another Pamphilliid sawfly, the web-spinning larch sawfly, Cephalcia lariciphila, in response to female derived odors and to a likely pheromone component, ortho-aminoacetophenone (Borden et al 1978;Baker et al 1983).…”

Sex Pheromone of the Pine False Webworm Acantholyda erythrocephala

Females of the pine false webworm Acantholyda erythrocephala (L) produce the sex pheromone (Z)-6, 14-pentadecadienal, which attracts flying males in the field. By using gas chromatography coupled with electroantennographic detection (GC-EAD) and mass spectrometry (GC-MS), we detected (Z)-6,14-pentadecadienal in volatile collections and in whole body extracts of female A. erythrocephala. Females, but not males, also exhibited a 25-carbon cuticular hydrocarbon, (Z,Z)-1,9,15-pentacosatriene, which can oxidize to (Z)-6,14-pentadecadienal upon exposure to air and sunlight. (Z,Z)-1,9,15-Pentacosatriene and (Z)-6,14-pentadecadienal identifications were corroborated by comparison with synthetic standards. (Z)-6, 14-Pentadecadienal is the second pheromone identified for pamphilliid sawflies, and the first to elicit strong field attraction, and thus offer potential as a pheromone lure to aid in control of this forest pest.

“…To our knowledge the only study on pheromoneinduced behaviour in phytophagous hymenopterans is that by Baker et al (1983) on the web-spinning larch sawfly, Cephalcia lariciphila Wachtl (Pamphilidae). Not even in Diprionidae, a Symphyta family in which the use of sex pheromone is well documented (Anderbrant, 1999), have these types of behaviour been investigated in any detail.…”

This study investigated the behaviour of male European pine sawflies, Neodiprion sertifer Geoffroy (Hym., Diprionidae), that were released and observed downwind from pheromone traps baited with 100 μg of the sex pheromone, (2S,3S,7S)‐3,7‐dimethyl‐2‐pentadecyl acetate. Releases were done at three distances; either at 5 m from one trap, or at 50 or 200 m from five traps, placed in a line perpendicular to the current wind direction. As control, males were released identically but without any pheromone source present. The behaviour of the males prior to take‐off was studied. A total of 1729 males were released, and 80% of them took flight. Males took off significantly faster in the presence of pheromone. Grooming was significantly more frequent in presence of pheromone compared with control. In all pheromone experiments significantly more males displayed grooming, wing fanning and take‐off towards the wind compared with the control. Weather data was simultaneously collected at the study site. Wing fanning was negatively correlated with wind speed. Grooming was not influenced by wind speed. Reduced levels of incoming short‐wave radiation lowered the take‐off frequency significantly. Pheromone‐induced behaviour in diprionids seems to be less distinct than in other insects, e.g., Lepidoptera.

“…54 The optimum blend of pheromones of Neodiprion sertifer has been shown to be (2S,3S,7S)-3,7-dirnethylpentadecan-2-01 acetate with a trace of the (2S,3R,7R)-isomer as a synergist.55 A component of the sex pheromone system of the web-spinning larch sawfly, Cephalcia lariciphila, has been identified as oaminoacetophenone. 56 The queen-recognition substance of the red imported fire ant Solenopsis invicta has been reported to be a mixture of the compounds (26)--(28).57…”
