Egg Masses

Invertebrate predation of egg masses of the gypsy moth has been little studied in North America despite its reported impact on populations of this pest in Eurasia and North Africa (Nonveiller 1959; Stefanov and Keremidchiev 1961; Hérard 1979). There, on occasion, this feeding guild has regulated local gypsy moth outbreaks (DeLépiney 1933). The most important predators were dermestids of the genera Anthrenus, Dermestes, Megatoma, and Trogoderma.

Lower Lethal Temperature

ABSTRACTGypsy moth Lymantria dispar (GM) is a polyphagous insect and one of the most significant pests in the forests of Eurasia and North America. Accurate information on GM cold hardiness is needed to improve methods for the prediction of population outbreaks, as well as for forecasting possible GM range displacements due to climate change.As a result of laboratory and field studies, we found that the lower lethal temperature (at which all L. dispar asiatica eggs die) range from –29.0 °C to –29.9 °C for three studied populations, and no egg survived cooling to –29.9 °C. These limits agree to within one degree with the previously established cold hardiness limits of the European subspecies L. dispar dispar, which is also found in North America. This coincidence indicates that the lower lethal temperature of L. dispar is conservative.Thus, we found that the Siberian populations of GM inhabit an area where winter temperatures go beyond the limits of egg physiological tolerance, because temperature often fall below –30 °C. Apparently, it is due to the flexibility of ovipositional behavior that L. dispar asiatica survives in Siberia: the lack of physiological tolerance of eggs is compensated by choosing warm biotopes for oviposition. One of the most important factors contributing to the survival of GM eggs in Siberia is the stability of snow cover.SummaryWithin the geographical range of Siberian gypsy moth populations, extreme temperatures go beyond the limits of the physiological tolerance of wintering eggs (–29.9 °C), and their survival depends on the choice of warm biotopes for oviposition.

AbstractWasps of the family Ichneumonidae recorded as parasitoids of Choristoneura Lederer (Lepidoptera: Tortricidae) in North America are summarized. A total of 113 species in 45 genera and 11 subfamilies have been reliably reared from 10 species of Nearctic Choristoneura. Twenty-one more species are listed as possible parasitoids of Nearctic Choristoneura, based on rearings from Palearctic Choristoneura species and (or) limited introductions to North America. Well-illustrated identification keys are provided to the subfamilies, all genera, and species of 39 of the genera. The species of Choristoneura used as hosts by the 113 ichneumonid species are tabulated, as well as the wasps’ geographic ranges. The biological characteristics of the ichneumonid subfamilies parasitizing Choristoneura spp. are described and compared. Erroneous Choristoneura host records and synonyms for all ichneumonid taxa previously recorded from Nearctic Choristoneura spp. are given. Phaeogenes gaspesianus Provancher is moved to Dirophanes Förster, forming D. gaspesianus (Provancher) comb. nov. New host records are Phaeogenes cacoeciae Viereck and Scambus hispae (Harris) on C. rosaceana (Harris), D. gaspesianus and Pimpla disparis Viereck on C. fumiferana (Clemens) (P. disparis having been introduced to New Brunswick to control the gypsy moth, Lymantria dispar (L.)), and Exochus turgidus Holmgren on C. occidentalis Freeman.

Potential Methods

The introduction of the Asian gypsy moth into novel environments continues with frequent interceptions in North America. There is a concern that these subspecies will pose a greater threat to the forests and urban environments of North America than the established gypsy moths (Lymantria dispardispar L.), due to their greater capacity for female flight. Asian gypsy moth populations vary in many key traits, including female flight capabilities. The potential impacts of female flight, in combination with the other key traits, on the ecology and spread of this insect are first discussed in this communication. This also provides the first review of most of the current literature on the variations in flight capability and flight distance of gypsy moth populations, as well as variation in other traits of concern and the potential methods of identification, with special attention paid to the Asian subspecies Lymantria dispar japonica Motschulsky and Lymantria dispar asiatica Vinkovskij. There are currently good tools for identifying the general origin of introduced gypsy moth populations, but these do not provide enough information to effectively manage introductions. Gypsy moth key traits differ among populations, even within each subspecies of the gypsy moth, so introduction of gypsy moths from other world areas into locations where the gypsy moth is already present could result in unwanted changes in gypsy moth biology. It also appears that the introduction of flight-capable females could enhance a population’s dispersal capability and require modifications to management protocols used for flightless females. Therefore, rapid tools to assess key traits in introduced populations are needed to adequately plan for, or deal with, new introductions into novel habitats.
