Abstract(Z,Z,Z)-1,3,6,9-Nonadecatetraene is a sex pheromone that attracts males of both the winter moth Operophtera brumata (L.) and the Bruce spanworm O. bruceata (Hulst). Tests were run to maximize the specificity of a pheromone trap for the winter moth by the addition of a previously discovered Bruce spanworm male inhibitor (BSMI), (E,Z,Z)-1,3,6,9-nonadecatetraene. Trap capture inhibition of O. bruceata would facilitate monitoring of winter moth as males of the two species are difficult to distinguish without dissection. Wind tunnel tests with O. bruceata males responding to the pheromone indicated that BSMI has a more potent inhibitory effect if males physically contact the compound. Field tests in an area where only O. bruceata was found demonstrated that pheromone-baited traps caught fewer O. bruceata with BSMI placed on the outside of the entrance holes than when it was placed on the inside of the trap, catching respectively 97 and 82% fewer males than traps baited with the pheromone alone. In an area where O. brumata predominated, BSMI, whether inside or outside the trap, did not affect O. brumata captures. However, O. brumata trap captures were reduced when BSMI was placed on rubber rings glued to the outside of the entrance holes to the traps even though control rings did not affect O. brumata captures. Evidence is presented indicating that hybridization is taking place between these two species where O. brumata has recently been introduced and that the response of the hybrids to the BSMI is intermediate between the two species.

Climate change may foster pest epidemics in forests, and thereby the fluxes of elements that are indicators of ecosystem functioning. We examined compounds of carbon (C) and nitrogen (N) in insect faeces, leaf litter, throughfall and analysed the soils of deciduous oak forests ( Quercus petraea  L.) that were heavily infested by the leaf herbivores winter moth ( Operophtera brumata  L.) and mottled umber ( Erannis defoliaria  L.). In infested forests, total net canopy-to-soil fluxes of C and N deriving from insect faeces, leaf litter and throughfall were 30- and 18-fold higher compared with uninfested oak forests, with 4333 kg C ha −1 and 319 kg N ha −1 , respectively, during a pest outbreak over 3 years. In infested forests, C and N levels in soil solutions were enhanced and C/N ratios in humus layers were reduced indicating an extended canopy-to-soil element pathway compared with the non-infested forests. In a microcosm incubation experiment, soil treatments with insect faeces showed 16-fold higher fluxes of carbon dioxide and 10-fold higher fluxes of dissolved organic carbon compared with soil treatments without added insect faeces (control). Thus, the deposition of high rates of nitrogen and rapidly decomposable carbon compounds in the course of forest pest epidemics appears to stimulate soil microbial activity (i.e. heterotrophic respiration), and therefore, may represent an important mechanism by which climate change can initiate a carbon cycle feedback.

Fall Cankerworm

The fall cankerworm, Alsophila pometaria (Harr.), and the winter moth, Operophtera brumata (Linn.), both feed to a great extent on the same tree species and prefer apple, Malus spp., red oak, Quercus rubra L., basswood, Tilia spp., white elm, Ulmus americana L., and Norway maple, Acer platanoides L. They also have similar life-histories and habits (Smith 1950 and 1953). Both lay their eggs on the trees in the fall and overwinter in this stage. The eggs hatch about the same time and the larvae of (both species mature about the third week in June. They drop to the ground and form cocoons at a depth of about an inch. The adults emerge about the same time, commencing usually during the last week in October and continuing until early December or until the ground freezes.

Bruce Spanworm

In a recently completed study involving pheromone trapping of the winter moth, Operophtera brumata (L.), and the Bruce spanworm, O. bruceata (Hulst), on Vancouver Island (Pivnick et al. 1988), I noticed that O. bruceata had wing colouration different from sympatric O. brumata. The west coast O. bruceata has a pale yellow-orange costal margin on the underside of the forewings and this is faint to absent in O. brumata (Fig. 1). It is also absent from O. bruceata in Saskatoon, which is interesting because some authors consider the west coast population of O. bruceata to be a separate species: the western winter moth, O. occidentalis (see Ferguson 1978; Pivnick et al. 1988). Descriptions of O. bruceata (Brown 1962) and O. brumata (Cuming 1961), and a taxonomic key to these two species (Eidt et al. 1966), do not mention any distinctive wing markings that could be used to separate the two species.

Larval Stages

Cyzenis albicans (Fall.) has been introduced into Nova Scotia as a control measure against the winter moth, Operophtera brumata (L.). The parasite attacks the late larval stages of the winter moth, pupates within the host in the ground, and emerges in the spring. The first liberations were made at Oak Hill near Bridgewater and the dates of releases as well as the numbers released were reported by Graham (1958) as follows: 1954, 31; 1955, 1008; 1956, 1005; 1957, 250. Graham made recoveries of C. albicans from rearings of larvae collected at Oak Hill in 1956 and 1957 and found that parasitism was less than two per cent both years. While liberations have been made at other locations in the Province since 1957, no further releases have been made at or near Oak Hill.

Five species of parasites reared from European material were released at Oak Hill, near Bridgewater, Nova Scotia from 1954 to 1956 as biotic agents against the winter moth, Operophtera brumata (L.) which had been established in Nova Scotia since before 1950. Recovery collections were made annually from 1955 to 1957. This work is still in progress, and in 1957 releases were made in four additional localities. Results of establishment of parasites from releases from 1954 to 1956 are reported below.
