Two moth species of the genus Operophtera, known as the Bruce Spanworm Moth (O. bruceata) and the introduced Winter Moth (O. brumata) manage to survive in conditions that would kill most other moths and butterflies. Ground beetles including Harpalus affinus (Schrank) and Pterostichus spp. Winter moth caterpillars can also drop from trees to nearby ornamental shrubs such as roses. Trees at risk are maples, oaks, cherries, basswood, ash, white elm, crabapple, apple, and blueberry, and they can also drop from your trees into your plant beds to feed on your perennials. In recent years, winter moth, gypsy moth and to a lesser extent, autumn webworm, have been concerns.

When feeding ends in mid-June the caterpillars migrate into the soil to pupate and emerge as moths. Protect the many natural enemies of caterpillars, including birds, predatory wasps, parasitic flies and wasps, ground beetles and other predators. Do pupal predators regulate the winter moth? Situations & Solutions .

Many around town have described the movement of these moths as falling snow. Examples include corn borers and bollworms. of winter moth pupae by unidentified generalist predators that was the most important mortality factor throughout the outbreak (Horgan et al., 1999). Avoid using insecticides and attract beneficial insects to the garden by planting flowers that supply pollen and nectar (see the Beneficial Insects Info Sheet in … According to an article in the Boston Globe, “The parasitic fly, a natural enemy of the winter moth, was expected to destroy more than 200,000 of the winter moths…” The Bedford Citizen posts each of the Town's official COVID-19 State of Emergency Task Force messages and other current news/updates on this page . The females are flightless and are commonly found crawling at the base of the trees. ... Predation of C. albicans pupae by the same generalist predators as winter moth pupae could constrain its ability to regulate the moth. Treatment for Winter Moth Pupae in the Soil: There are virtually no controls for this pest in this life stage other than natural predation by such organisms as ground beetles, small mammal predators (especially shrews), and wasp predators. Certain native beetles, like carabids (ground beetles) and staphylinids (“oil” beetles) may act as predators of this pest, especially in the pupal stage, in the leaf litter or soil. These moths all have wingless females that emerge from pupae in the soil and crawl up trunks to lay eggs on branches. A .

Latto, J.; Hassell, M. 1987-11-01 00:00:00 Oecologia (Berlin) (1987) 74 : 153-155 Oecologia 9 Springer-Verlag 1987 Short communications J. Latto and M.P. Winter moth caterpillars are now stripping foliage from many kinds of deciduous trees from Mystic, Conn. to coastal Maine, Elkinton says. Pupae are attacked by wasps (Cratichneumon) and some soil insects and predators such as mice and shrews. PREDATION ON THE SOIL-DWELLING STAGES OF THE WINTER MOTH AT WYTHAM WOODS, BERKSHIRE BY R. EAST* Ruakura Agricultural Research Centre, Private Bag, Hamilton, New Zealand INTRODUCTION Long-term population studies of the winter moth (Operophtera brumata (L.)) on oak (Quercus robur L.) at Wytham Woods, Berkshire, have revealed that the mortality of the soil-dwelling … Some moths, particularly their caterpillars, can be major agricultural pests in many parts of the world. The winter moth, Operophtera brumata , shows varying population dynamics in different host plant habitats.Populations in Sitka spruce, Picea sitchensis, plantations and in Scottish moorlands have a tendency to outbreak that is not shown by winter moth in lowland oak woods. In fact, some moths have evolved defenses against their winged predators.
