Download Distribution, phenology, and parasitism of the winter moth, (Operophtera brumata L.), in western Oregon
However, rates of larval parasitism were low, averaging only % and % in both years, respectively. Two exotic parasitoids, C. albicans and A. flaveolatum, were introduced into areas of known winter moth infestations in and : Diana Nalani Kimberling.
In Oregon, Operophtera brumata is distributed throughout the northern region of the Willamette Valley, where it is commonly found on commercial hazelnut, crabapple (Malus sylvestris) and flowering plum (Prunus cerasifera). The adults emerge in early November to December, eggs overwinter, larvae hatch in mid-March and develop through 5 instars, and pupae occur in the soil from May to by: Oak (Quercus sp.) and willow (Salix sp.) hosted significantly higher caterpillar abundances than other tree taxa, with winter moth exhibiting similar trends and invariantly proportionate across tree taxa.
Caterpillar peak phenology was broadly similar between tree by: 4. Phenological diversity in the interactions between winter moth (Operophtera brumata) larvae and parasitoid wasps in sub-arctic mountain birch forest - Volume Issue 6 - O.P.L.
Vindstad, S.B. Hagen, J.U. Jepsen, L. Kapari, T. Schott, R.A. ImsCited by: The literature on the ecology and physiology of winter moth is reviewed. The factors maintaining the unusual phenology are discussed. It is concluded that the larval stage is early because mature leaves of many host trees are unsuitable as food, because parasitism against later larvae is more intense, and because summer temperatures may be Cited by: term studies showed that as ofparasitism.

AbstractA classic system for studying trophic mismatch focuses on the timing of the spring caterpillar peak in relation to the breeding time and productivity of woodland passerine birds.
Most work has been conducted in single-site oak woodlands, and little is known about how insights generalize to other woodland types or across space. Here we present the results of a 3-year study on the. This phenomenon has occurred in systems such as Panolis flammea (Denis & Schiffermüller) (Lepidoptera: Noctuidae) (pine beauty moth), for which host phenology and subsequently parasitism are different on different host plants (Hicks et al.
), and for Cotesia melanoscela (Ratzeburg) (Hymenoptera: Braconidae), a parasitoid of gypsy moth. Norun M. Hansen, Rolf A. Ims, Snorre B. Hagen, No Impact of Pupal Predation on the Altitudinal Distribution of Autumnal Moth and Winter Moth (Lepidoptera: Geometridae) in Sub-Arctic Birch Forest, Environmental Entomology, /, 38, 3, (), ().
In the processionary moth Thaumetopoea processionea, for example, Wagenhoff et al. showed that cold days (winter reduce the subsequent heat requirement for egg-hatching.
Nevertheless, springtime warming has been more than adequate to compensate for a long-term reduction in the number of cold days: the authors’ phenology model for. In this study, we document the altitudinal distribution of winter moth outbreaks in a large coastal area in northern Norway.
We show that, in the present winter moth outbreak, defoliated birch stands were seen as distinct zones with a rather constant width in the uppermost part of the forest and where the upper limit coincided with the forest line.
Population cycles of the winter moth (Operophtera brumata) in sub-arctic coastal birch forests show high spatiotemporal variation in amplitude. Phenology in moth-parasitoid interactions The two forest-defoliating geometrid moth species Operophtera brumata and Epirrita autumnata are known to exhibit different altitudinal distribution patterns in northern birch forests.
One possible explanation for this is that altitudinal climatic variation differentially affects the performance of two species through mismatching larval and host plant phenology.

Impacts on the winter moth involve significant evolution of egg hatch phenology (van Asch et al. in preparation) as well as population dynamic effects (Hunter et al.
(a) Bay checkerspot As we have described, the baseline condition of bay checkerspot involved routinely high mortality caused by phenological mismatch with its host plants.

The book deals with recording methodology employed, together with the ecology of many species. It also examines other key concepts such as parasitism, the arrival of new species over time and the potential value of local studies such as these in.
Budburst timing varies among and within tree species (Van Dongen et al., ).Advances or delays in leafing are important for insect life cycles (Foster et al.
).The close coincidence of budburst and larval hatch of spring-feeding generalist moth species was reported in many studies (Hunter ; Tikkanen and Julkunen-Tiitto ; Van Asch et al. ; Foster et al.

Posted on by cecej. UK moths nine of the most colourful and distinctive Natural History. In a recent paper, Salis et al.  examined the phenology of eggs of the winter moth (Operophtera brumata L.) and proposed a phenology model in which developmental response is dependent on the “interactive effects of temperature and developmental stage” (p.
).However, the authors examined only one stage—the egg stage—and what they actually observed was the far more interesting. Following the establishment of these two parasitoids, parasitism by C.
albicans increased rapidly to 50% in and life table data showed that a considerable increase in prepupal mortality was responsible for the collapse of the winter moth population in the main study site (Embree a,b). Parasitism by A.
Winter Moth. Winter moth, Operophtera brumata. (Lepidoptera: Geometridae), is a non-native invasive defoliator from Europe that was discovered in Massachusetts in the late s.
Winter moth has now been found throughout the eastern half of Massachusetts and into Rhode Island, Connecticut, Long Island (NY), southeastern New. Winter moth caterpillars are often found in association with both the fall and spring cankerworms, as well as Bruce spanworm (Operophtera bruceata), which are very similar in appearance and have similar feeding patterns to that of the winter moth caterpillar.
Fall cankerworm caterpillars have “2 and ½” pairs of prolegs: two pairs of the. The pervading paradigm in insect phenology models is that the response to a given temperature does not vary within a life stage.
The developmental rate functions that have been developed for general use, or for specific insects, have for the most part been temperature-dependent but not age-dependent, except where age is an ordinal variable designating the larval instar.
The different spatial distribution of outbreaks of the two dominant birch forest geometrids in northern Fennoscandia has been thought to have a climatic origin, with the winter moth presumed to take advantage of warmer climates along the coast and in the lower sections of the forest compared to the autumnal moth (TenowBylund ).

Using data from the Devon Moth Group database, Phil Dean has created two really useful resources about the timing (phenology) of moths in the county. One shows the main flight period (in months) for each macro-moth species and the other lists the macro-moth species likely to be on the wing in Devon in each month of the year.
Increasing leaf toughness is a proximate, though probably not ultimate, factor preventing late larval feeding by the winter moth, the commonest spring species on oak.
Early feeding coincides with maximum leaf protein content and mimum leaf sugar content, with suggests that availability of nitrogen, rather than of carbohydrate, may be a limiting. Studies on the phenology and ecology of the pine processionary moth (Thaumetopoea pityocampa) were carried out in plantations of the black pine (Pinus nigra) in four localities in the South-Eastern Rhodope Mts.
- near the town of Ivaylovgrad and in the region of Kirkovo, the Kandilka and Austa Villages. A phenologically atypical population "summer form" (SF) was established on the territory of. The life cycle of Nyctemera annulata takes 6–7 weeks to complete and requires warm weather with the winter being passed in the pupa stage.
The moth will lay yellow eggs on the undersides of herbaceous Senecio species. The eggs gradually become dark and will hatch after approximately 6 – 7 days. The winter moth cycle has typically been phase-locked with that of the autumnal moth, but with a 1–3- year phase lag.
We examined potential effects of natural enemies on this phase lag using field experiments and observational data.
We found that larval parasitism was significantly higher in autumnal than in winter moths. Kukal, 0. Winter mortality and the function of larval hibernacula during the year life cycle of an Arctic moth, Gynaephora groenlandica.

The parasitoids of the apple ermine moth and their parasitism rates were determined through collection and rearing of pupae in 4 geographic regions from to Collections were made during a total of 20 apple ermine moth seasons from 16 sites located in Honshu (in and ) and Hokkaido (), Japan, Shanxi, China (), and Korea.
Conversely, the European defoliators - larch bud moth (Zeiraphera diniana) and the southern distribution of the winter moth (Operophtera brumata)- have been significantly disadvantaged to the point that outbreak population sizes may no longer be possible, despite a long history of regular outbreaks (Visser et al., ; Johnson et al, ).The brown-tail moth (Euproctis chrysorrhoea) is a moth of the family is native to Europe, neighboring countries in Asia, and the north coast of Africa.
Descriptions of outbreaks, i.e., large population increases of several years duration, have been reported as far back as the s. The life cycle of the moth is atypical, in that it spends approximately nine months (August to April.moth using a temperature-driven model of gypsy moth development.
This model was validated with field observations from southern Vancouver Island. The phenology model was then used to develop area-wide forecasts of target events in the seasonal life history of gypsy moth .
