Volume of urine excreted by mature larvae reared on an artificial diet was 1.5 times higher than that of larvae reared on mulberry leaves, and the urea content in the urine per larva was concentrated by approximately 86 times in the larvae reared on an artificial diet. Cambridge, Massachusetts. Polyphemus caterpillars use the full range of cocoon placement behaviors found in the subfamily Saturniinae as described by Wagner and Mayfield (1980): 1) Attached longitudinally and permanently to a twig so that the cocoon does not fall to the ground during the winter. The polyphemus moth also has been known by the genus name Telea but it and the Old World species in the genus Antheraea are not considered to be sufficiently different to warrant different generic names. Miller TA, Machotka SV. Camden, Maine. Wagner WH, Mayfield 1980. Also, during the first day after emergence, the moth voids the liquid meconium which is composed of the breakdown waste products of the old larval tissues. 2012. Results on All rights reserved.

The chorion, or eggshell, is commonly pierced by respiratory openings that lead to an air-filled meshwork inside the shell.For some insects (e.g., cockroaches and mantids) a batch of eggs is cemented together to form an egg packet or ootheca. 1979, Townes 1944), and one species of proctotrupoid wasp (Collins and Weast 1961). Int. -early stage loss-effective rate of rearing-pupation rate-reproductive rate-egg production. Males can fly for miles to reach a female. Figure 6. Photograph by Donald W.

Besides ultra-structures, the development pattern of the two types of spores is also different. This silkworm is raised in China for its silk. Eggs are laid singly or in groups of two or three on leaves of the host plant (Opler et al. Lepidoptera of Florida. If attacked, polyphemus caterpillars as well as those of many other bombycoid moths make a clicking noise with the mandibles - sometimes as a prelude to or accompanied by defensive regurgitation of distasteful fluids.

Therefore, in order to escape their cocoons they secrete a trypsin-like cocoonase enzyme to digest the sericin component of the silk at the anterior end of the cocoon to soften it (Kafatos and Williams 1964, Hruska et al. The silkworms are reared out door and as such are exposed to vagaries of nature. Caterpillars are solitary and develop through five instars. Waldbauer GP, Sternburg JG, George WG, Scarbrough AG. J.

They are found from southern Canada down into Mexico and in all of the lower 48 states except for Arizona and Nevada (Tuskes et al. Old cocoons made by caterpillars that were parasitized by ichneumon wasps have an exit hole made by the wasp that is similar to that made by woodpeckers. Eggs: The slightly oval flattened eggs are white with two broad brown rings and are cemented to the substrate with a dark brown adhesive. It is found in Assam in northeast India where 99% of its production occurs.. Photograph by Donald W. Hall, University of Florida.

Waldbauer GP. 138 pp. Adults: The adult wingspan is 10 to 15 cm (approximately 4 to 6 inches) (Covell 2005). The wild silk moth is purely multivoltine in nature and four life cycles are completed in a year viz April-May, June-July, August-September, and October-November respectively. Afternoon emergence allows time for expansion and drying of the wings prior to the evening flight period. The real color of the egg is off-white (china-white), but because the surface is covered with a colloid substance (with brown gum), it appears to be brown. The native place of this species is Assam where it has now become a good source of cottage industry. Polyphemus antennae are quadripectinate (comb-like on four sides) with those of males being larger than those of females. 1996) - possibly to obscure their presence from predators The presence of large larvae on branches overhead may often be detected by the presence of frass (caterpillar droppings) on pavement of driveways or parking lots. Arnaud PH. Also, the much larger developing antennae of male pupae touch each other at the mid-ventral line while those of female pupae do not. Powell JA. Frass (fecal pellets) of larva of polyphemus moth, Antheraea polyphemus (Cramer). The insects then emerge out from the cocoons. 1967. Photograph by Donald W. Hall, University of Florida.

Godfrey GL, Jeffords M, Appleby JE. Fifth instars have a yellow band that extends around the dorsal and lateral areas directly behind the head, yellow bands laterally at the bases of the thoracic legs and a yellow mid-ventral line that extends the length of the abdomen. 1987. This silk is produced from the worm Antheraea assama also belonging to the family Saturniidae. Holland WJ.
