Tent Caterpillar

The forest tent caterpillar, Malacosoma disstria Hübner, is the most widely distributed indigenous tent caterpillar in North America (Furniss and Carolin 1977). The forest tent caterpillar has been recognized as an important defoliator of a wide variety of deciduous hardwood trees throughout its range for many years (Batzer and Morris 1978). Although this univoltine insect is called a tent caterpillar, it is unlike other Malacosoma species in that the larvae do not construct tents. Instead, forest tent caterpillars spin silken mats on the trunks and large branches where they congregate to molt or rest from feeding. Larvae also deposit silk in strands along which they travel to and from feeding sites. The caterpillars themselves are relatively harmless to people (i.e., they do not bite or sting) although a few people have an allergic reaction to handling them. This document is EENY-184 (originally published as DPI Entomology Circular 385), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

The coriander aphid, Hyadaphis coriandri (Das), was found for the first time in North America on fennel (Foeniculum vulgare Mill.) at Orange County residences in Apopka and Orlando. In December 1998, an infestation also was found on coriander (Coriandrum sativum Linnaeus) and dill (Anethum graveolens Linnaeus) at a residence in Tampa, Hillsborough County. This document is EENY-296 (originally published as DPI Entomology Circular 399), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

In North America there are 32 species of Kermesidae in five genera, but in northeastern North America there are only nine species in four genera (Eriokermes, Nanokermes, Allokermes, and Kermes). The Allokermes spp. that are of economic importance in Florida are A. cueroensis (Cockerell), A. galliformis (Riley), and A. kingii (Cockerell). The kermes scale, Allokermes kingii (Cockerell), is an important pest on oak (Quercus spp.) trees. This document is EENY-338, one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Except for two pantropical species (Edwards 1979), the jumping spider most frequently encountered in Florida is Phidippus regius C.L. Koch. This species is aptly named in terms of its size, as it is the largest jumping spider in eastern North America. The species is found in the southeastern U.S., the Greater Antilles, and the Bahamas, but is most common in peninsular Florida. This document is EENY-152 (originally published as DPI Entomology Circular 223), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Leafcutting bees are important native pollinators of North America. They use cut leaves to construct nests in cavities (mostly in rotting wood). They create multiple cells in the nest, each with a single larva and pollen stored for the larvae to eat. Leafcutting bees are important pollinators of wildflowers, fruits, vegetables and other crops. Leafcutting bees, Osmia spp. are even used as commercial pollinators (like honey bees) in crops such as alfalfa and blueberries. This document is EENY-342, one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

The cyclamen mite, Phytonemus pallidus (Banks), (family Tarsonemidae), was first noticed in New York in 1898 and in Canada in 1908. The cyclamen mite was described by Banks (1901) as Tarsonemus pallidus from leaves of greenhouse chrysanthemums at Jamaica, New York. Today, it is generally distributed throughout the country. Ewing (1939) considered Tarsonemus fragariae Zimmermn and T. destructor Reuter to be synonyms of T. pallidus Banks. Beer (1954) placed it in the genus Steneotarsonemus. However, Linquist placed in it the genus Phytodromus in 1987. The mites are often found on the corms of cyclamens in storage and are thus transported by trade. It has been spread on plants in unopened leaflets and on the tubers of cyclamen to all parts of the world. This mite requires high humidity and avoids light. It overwinters in the adult stage in the temperate zone. It is widely distributed throughout North America, Hawaii, Europe and Asia. This document is EENY-178 (originally published as DPI Entomology Circulars 25, 177 and 306), one of the Featured Creatures series of the Entomology and Nematology Department, Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Tent Caterpillar

Forest tent caterpillar (Malacosoma disstria Hübner) is a major defoliator of hardwoods throughout North America, including aspen (Populus tremuloides Michx.). M. disstria has been a major concern in many parts of Canada for the last two decades, but until recently in British Columbia it was considered an aesthetic concern only. However, with the increasing interest in the cultivation of hardwoods for fibre, and more recently for fuel, this insect could become a major concern in hardwood management. Records of past M. disstria outbreaks in British Columbia were summarized. The locations and intensity of six outbreaks were overlaid on biogeoclimatic units to determine which biogeoclimatic zones have experienced repeated outbreaks of M. disstria. Between 1944 and 2003, M. disstria outbreaks have become larger in extent and longer in duration. Analysis indicated that aspen stands in the Boreal White and Black Spruce (BWBS), Sub- Boreal Spruce (SBS) and Interior Cedar-Hemlock (ICH) biogeoclimatic zones have been most frequently attacked. In the BWBS zone, most affected areas (93.3%) were defoliated for only one year (lightly). In the SBS and ICH zones, areas attacked by M. disstria tended to be defoliated two or more consecutive years (40.2% and 56.2%, respectively), and had a greater chance of being more severely defoliated than aspen stands in the BWBS zone.

Tent Caterpillar

Biological and meteorological records were examined for periods when outbreaks of the spruce budworm, Choristoneura fumiferana (Clem.), were known to have occurred in northeastern North America. The survey showed that the following significant events occurred during the period of three to four years preceding an outbreak. Decreasing annual numbers of low pressure centers passed over the area in which the outbreak later occurred. Therefore, the outbreak began at a time of decreased or minimal storminess. Drought occurred, chiefly in June and July, but also occasionally in spring and autumn. Annual increments of host trees on dry sites declined. Outbreaks of the forest tent caterpillar, Malacosoma disstria Hbn., occurred, particularly in Ontario. These events, in aggregate, occurred so consistently before spruce budworm outbreaks that they have future predictive value. In addition, they reinforce some suggestions made by earlier authors and suggest modifications of hypotheses concerning the behavior of developing populations of the spruce budworm.

AbstractEntomophthora crustosa n. sp. pathogenic for Malacosoma species (principally M. disstria Hbn.), is described. It is characterized in the conidial state by a hymenial coating which, at maturity, forms a crust-like covering, cinnamon brown, over the surface of infected insects, and by conidial size. In the resting spore (zygospore) state the distinguishing attributes are ornamentation of the zygospores and their mode of development. The pathogen grows readily on coagulated egg-yolk media.The fungus is briefly compared with 10 other closely related Entomophthora species. Entomophthora crustosa seems to be of widespread occurrence in eastern North America.

The forest tent caterpillar, Malacosoma disstria Hiibner, is widely distributed throughout North America and is subject to a variety of naturally occurring infectious diseases, including a nuclear polyhedrosis virus (NPV). NPVs have been isolated from several Malacosoma species in North America and Europe, including M. disstria, M. neustria, M. americanum, M. fragile, M. alpicola, M. californicum, M. pluviale, and M. constrictum (Stairs 1964). The viruses isolated from all North American species of Malacosoma may be cross transmitted from one species to another (Clark 1958). Distinctive isolates of NPV have been characterized from populations of M. disstria in Alberta (Keddie and Erlandson 1995) and Ontario (Ebling and Kaupp 1995).
