“…In Sweden none of the three analogs, (-SS)Ac, (S-S)Ac, or (SS-)Ac, elicited catches of males when used in traps by themselves, and, further did not did not affect the catches of males when added to (SSS)Ac. This suggests that the analogs did not bind effectively to the antennal receptors tuned to (SSS)Ac (Hansson et al, 1991). In Japan, however, (SS-)Ac, in amounts 10-20 times higher than that of (SSS)Ac, caught male N. sertifer in traps (tests 7 and 9, Tables 5 and 6).…”

“…While the presence of a methyl group at each of the three stereogenic carbons apparently is essential to evoke an adequate response from males, the functional group on carbon 2 appears less critical; (SSS)Ac and (SSS)Pr are similarly active, both electrophysiologically and behaviorally (this study; Hansson et al, 1991;Anderbrant et al, 1992aAnderbrant et al, , 2000. Diprion pini shows an even broader tolerance to different esters, with the acetate, propionate, and iso-butyrate esters of (2S,3R,7R)-3,7-dimethyl-2-tridecanol being attractive Anderbrant et al, 2005).…”

“…One obstacle to such a study is that the main pheromone component in both species stimulates several neurons with different amplitudes (Hansson et al, 1991;Anderbrant et al, 1995), making reliable quantifications difficult. Detailed molecular structure-electrophysiological response studies have been undertaken for other systems.…”

Field Response of Male Pine Sawflies, Neodiprion sertifer (Diprionidae), to Sex Pheromone Analogs in Japan and Sweden

et al. 2010

The pine sawfly Neodiprion sertifer (Geoffroy) uses the acetate or propionate of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol) as pheromone components, with the (2S,3R,7R)-isomer being antagonistic, synergistic, or inactive according to the population tested. In this study, we tested the attraction of males to the acetates of three analogs of diprionol, each missing one methyl group, viz. (2S,7S)-7-methyl-2-pentadecanol, (2S,6S)-2,6-dimethyl-1-tetradecanol, and (2S,3S)-3-methyl-2-pentadecanol. None of the analogs alone, or in combination with diprionol acetate, was attractive in Sweden, even at 100 times the amount of diprionol acetate attractive to N. sertifer. In Japan, the acetate of (2S,3S)-3-methyl-2-pentadecanol attracted males when tested in amounts 10-20 times higher than the acetate pheromone component. The acetate esters of the (2S,3R)-analog and the (2S,3R,7R)-isomer of diprionol also were tested in combination with the pheromone compound (acetate ester). Both compounds caused an almost total trap-catch reduction in Sweden, whereas in Japan they appear to have relatively little effect on trap capture when added to diprionol acetate. Butyrate and iso-butyrate esters of diprionol were unattractive to N. sertifer in Sweden. In summary, there exists geographic variation in N. sertifer in responses to both diprionyl acetate and some of its analogs.

“…A blank solvent stimulus was included in all experiments to account for mechanical responses. The recorded EAG responses were normalized by using a standard stimulation (Hansson et al 1991) before (S b ) and after (S a ) each experimental stimulation (E). The responses were normalized according to E/ (S b + S a /2).…”

Stereoisomeric composition of the sex pheromone of the pine sawfly Microdiprion pallipes (Hym., Diprionidae)

et al. 2003

The basic chemical structure of the sex pheromone of the pine sawfly Microdiprion pallipes (Fallén) has earlier been identified as the propionate ester of (2S,3S,7R/S,11R/S)/(2R,3R,7R/S,11R/S)-3,7,11-trimethyl-2-tridecanol. We now report the results from further investigations on the male response to individual stereoisomers and to blends of stereoisomers, both in electroantennographic (EAG) recordings and in field trapping experiments. We also present our attempts to determine the stereochemistry of the compounds present in females of M. pallipes. By comparing gas chromatograms and mass spectra obtained from natural extracts with those from synthetic compounds it was found that the females contain one or more of the four (2S,3S,7R/S,11R/S)-3,7,11-trimethyl-2-tridecanol isomers (SS++-1). The active pheromone component is the corresponding propionate ester 2. In EAG experiments, males responded most strongly to five propionate ester samples, namely two four-isomer blends: SS++-2 and SR++-2, and three individual stereoisomers: SSSR-, SRRR-and SRSR-2. In a series of field trapping experiments it was found that males were attracted to the SR++-2 four-isomer blend and to the individual isomer SSSR-2. Based on the EAG-recordings and field responses of males and the stereoisomers found in the females, we suggest that the propionate ester of (2S,3S,7S,11R)-3,7,11-trimethyl-2-tridecanol (SSSR-2) is used as a main component of the sex pheromone in M. pallipes. Apparently the males react to other stereoisomers in addition to that or those produced by the females.

“…The European pine sawfly Neodiprion sertifer Geoffroy occurs in the northern hemisphere from Europe to eastern Asia and has been introduced into North America (Kolomiets et al, 1979). Adult females attract males with the aid of a sex pheromone (the acetate or propionate ester of (1S,2S,6S)-1,2,6-trimethyl-tetradecanol (diprionol)) and synthetic pheromone stimulates male antennae (Hansson et al, 1991) and attracts males in the field (Anderbrant et al, 1992b). It has been shown that N. sertifer males respond to synthetic pheromone from 200 m away (O È strand et al, 2000).…”

1 Two new concepts describing the origin of insects caught in an attractive trap are presented. 2 Male European pine sawflies Neodiprion sertifer Geoffroy (Hymenoptera: Diprionidae) were marked and released from 50, 100, 200, 400 and 800 m in the four cardinal directions around a centrally placed pheromone trap. 3 Based on linear regression of transformed data, we calculated the seasonal sampling range (r s ) as 1040 m. 4 We estimated the previously defined`effective sampling area' (a) at 4.9 ha, assuming that the insects are evenly distributed around the trap and that they are attracted from a circular area around it. This is the area from which all insects originate if the trap is 100% effective within the area but captures nothing outside of it. The effective sampling area reveals nothing about the origin of the insects caught. We defined the Cumulative Proportional Catch (CPC) that gives the proportion of the trap catch that originates from an area within a distance r from the trap. At r r s CPC 1, and in our study 50% of the captured insects originated up to 450 m from the trap. Thus, for the trap used in this study, a relatively large proportion of the catch originates some distance from the trap. 5 We also defined the Catch Concentration (CC), which is the ratio of the radius of the effective sampling area (r a ) to r s . For our data, CC 0.12, which is intermediate to high compared to the few other studies that we have extracted information from. If r a is considerably lower than r s , then only a small proportion of the insects caught originate from close proximity to the trap. When r a is close to r s , the catch adequately mirrors the population within most of its sampling range. 6 By using these two new concepts, we will better understand why monitoring traps mirror the local population in some cases but not in others. This will help in designing more reliable monitoring programmes.
