Sphecidae (Hym., Aculeata) recorded from bark beetlepipe traps and some faunal notes from South NorwayTORSTEIN KVAMME AND RUNE AXELSSONKvamme, T. and Axelsson, R. 1983. Sphecidae (Hym., Aculeata) recorded from bark beetlepipe traps and some faunal notes from South Norway. Fauna norv. Ser. B. 30, 57 - 59.Eleven species of Sphecid wasps were recorded from bark beetle pipe traps. It is no reason tobelieve that the trapped specimens have responded to the synthetic bark beetle pheromones.Pemphredon lugens Dahlbom, 1842 and P.flavistigma Thomson, 1874, are presented new tothe Norwegian fauna.Torstein Kvamme, <strong>Norsk</strong> institutt for skogforskning, Box 61, N·1432 As-NLH, Norway.Rune Axelsson, Sveriges Lantbruksuniversitet, Inst. for viixt- och skogsskydd, Box 7044,S·750 07 Uppsala, Sweden.The family Sphecidae is poorly investigated inNorway, as shown by Lombholdt 0975,1976).While 155 species are known to occur in Sweden,only 95 species are known from Norway.About 50 % of these species are arboreal (Lombholdt1975). Indirectly the low number of speciesemphesizes the low level of collecting activityin Norway.It is well known that Sphecids can be recordedin window traps (Axelsson 1982), butcatches from drain pipe traps have not been prei'lented.The present paper deals with specimens caughtin bark beetle drain pipe traps and singlerecords representing new faunal divisions. Thefaunal divisions are in agreement with Strand(943), and in ad,dition the EIS-grid numbers areadded. The specimens are preserved in the collectionof the Norwegian Forest Research Institute.SPHECID WASPS FROM BARK BEETLEDRAIN PIPE TRAPSDuring the years 1979 to 1982 an extensive integratedcontrol program for the spruce bark beetle([ps typographlls) was carried out in Norway.The methods and trap models are describedby 8akke & Strand (] 98 0. All insects trappedin 1979 in a total of 216 traps at 20 localitieswere carefully examined. Sphecid wasps werefound amongst bark beetles at 12 ofthe localities(Fig. 1). The number of each species at the differentsites are presented in Tab. 1. All specimenscaught in the traps belonged to species nesting inFauna norv. Ser. B. 30.. 57-59. Oslo 1983holes etc., mainly in decayed wood. None ofthem are known to prey on bark beetles, butprey on Diptera and Hemiptera (Lombholdt1975,1976). The hole-nesting habits of this species,the small number of specimens trapped,and the relatively large proportion of females,indicate that the Sphecids were attracted to thetraps in search of a suitable breeding place. It isprobably a visual stimulus and not a result ofkairomone response as known from predatorssuch as Thanasimlls spp. (Bakke & Kvamme1978, 1980.Comments to some of the species presented in Table1:Pemphredon lugens Dahlbom~ 1842 is hitherto notknown from Norway, although this species is widelydistributed in Sweden and Finland, and oneof the most common species of the genus (Lombholdt1975). Probably is P. lugens widely distributedin Norway, but previously overlooked.P. montanus Dahlbom, 1842 is new to South Norway,previously known only from Nn0, Fi andF0. In Sweden the species is recorded from almostthe entire country except the coastal areas in thesouthern parts. All the records are from inlandareas (Tab. 0.P. wesmaeli (A. Morawitz, 1864) is previouslyknown only from western parts of the country (Riand SFi).Ceratophorus morio (van der Linden, 1829). This isthe second Norwegian record, known only fromAK:Oslo. According to Lombholdt (1975), C. moriais not common and is sporadically found inScandinavia.Passaloecus borealis Dahlbom, 1845 is a poorlyknown species, in Norway previously found onlyin NTi:Verdal and not in Nsy (Lombholdt 1975).57
