In the last red feces excreted by larvae immediately before cocooning the value of urea was about 6 times higher in the larvae reared on an artificial diet. All rights reserved. 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. Eggs are laid singly or in groups of two or three on leaves of the host plant (Opler et al. KHANIKOR D.P. The moths then tear their way from the cocoon by the use of chitinous spurs on the thorax near the bases of the front wings while moving about the cocoon in a circular pattern (Hilton 1965).

Cocoon of polyphemus moth, Antheraea polyphemus (Cramer) with an ichneumon wasp cocoon. Their life-span is only 3-6 days. Figure 14. Cocoon and Pupa: The single-layered cocoon is thicker and more elliptical than the cocoon of the luna moth (Wagner 2005). 1980. ... Name the life cycle of a silk moth in cyclic form. Polyphemus caterpillars are polyphagous and have been reported in nature from over 50 species of broad-leaved plants (Ferguson 1972, Heppner 2003, Tietz 1972, Tuskes et al. Muga silk is a cottage industry in Assam. Figure 4. The influence of temperature on the photoperiodic regulation of diapause in saturniids. Afternoon emergence allows time for expansion and drying of the wings prior to the evening flight period. 1972. The sex pheromone has been characterized as a 90:10 mixture, respectively, of trans-6,cis-11-hexadecadienyl acetate and trans-6,cis-11-hexadecadienal (Kochansky et al. Eri silk: 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. Attachment by a peduncle may be more common in the South (Wagner 2005). Immediately after hatching, caterpillars eat their egg shells (Opler et al. 1996). Either caged or tethered females can be used to attract wild males. Because the name Antheraea has been used more often in the literature, Ferguson (1972) recommended using that name rather than Telea to avoid confusion. Lepidoptera of Florida. Enzymatic mechanism for the escape of certain moths from their cocoons. Tuskes PM, Tuttle JP, Collins MM. Waldbauer GP, Sternburg JG, George WG, Scarbrough AG. Antheraea mylitta is one of the wild nonmulberry silkworms, ... mylitta, and Antheraea assama play an important role in rural economy of many populous developing nations. Worth CB, Muller J. Young AM. This notch is lacking in males. This Saturniidae silkworm has four major stages in its life cycle-larva, cocoon, moth and egg. The life-cycle of these four types of silk moths are much in common, as they lay eggs, from which caterpillars hatches. The hole is like those reported by Waldbauer et al. 3) Attached among leaves on trees but with no peduncle so that most fall to ground during winter. Figure 12.

Maximum reported dimensions in millimeters are 2.4 × 2 × 1.52 (length × width × height) (Peterson 1965). The polyphemus moth is univoltine (one brood per year) from Pennsylvania northward (Holland 1968) and bivoltine (two broods per year) from the Ohio Valley southward (Tuskes et al. Eri silkworm (Attacus ricinni): 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. However, they can be differentiated from cocoons attacked by woodpeckers by the presence inside of the cocoon of the ichneumon and the cadaver of the polyphemus caterpillar. & DUTTA S.K.

It is referred to as Tussah, Chinese Tussah, Oak Tussah, or Temperate Tussah. The golden silk spun by Indian golden silkmoth Antheraea assama, is regarded for its shimmering golden luster, tenacity and value as biomaterial. … The first life cycle is completed within 28 to 32 days, which includes the period from the hatching of 1 st instar larvae to the formation of the pupa inside the cocoon. Science 146: 538-540. It is named after Polyphemus, the giant cyclops from Greek mythology who had a single large, round, eye in the middle of his forehead (Himmelman 2002). This silk is produced from the worm Antheraea assama also belonging to the family Saturniidae. 1977). Figure 13.

The climate as well as food (som, Machilus bombycina and soalu, Litsea polyantha) has profound impact on the developmental biology of muga silkworm, Antheraea assama Ww. Eggs: The slightly oval flattened eggs are white with two broad brown rings and are cemented to the substrate with a dark brown adhesive. 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.

Antheraea assamensis, known as the muga silkworm as a larva and Assam silk moth as an adult, is a moth of the family Saturniidae.The species was first described by T. W. Helfer in 1837. Polyphemus antennae are quadripectinate (comb-like on four sides) with those of males being larger than those of females. It is an interesting finding in the present study that, spores of N. bombycis produced two types of spores and multiplied in different gender under the influence of the host's reproductive role and physiology for transmission of disease. Kochansky J, Tette J, Taschenberg EF, Carde RT, Kaissling K-E, Roelofs WL. its behavioural responses to physical structure and chemical features of the host plants. 1963. Caterpillars of Eastern North America. The large hind wing eyespots are ringed with prominent yellow, white (partial) and black rings. Adult eclosion (emergence from pupa) typically occurs in the afternoon with males usually beginning emergence several days before females from the same brood. 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. Of this only larval stage is feeding period. Vol. Older instars are yellow-green, and the setae become relatively less prominent with each molt. Received directly from India, 2009. ... Microscopists are easily able to detect mature spores but typically miss Nosema spp. 1092 pp. Fifth instar male larvae can be differentiated from female larvae by the presence of a black pit on the ventral aspect of the ninth abdominal segment of males that is lacking in females (Miller and Machotka 1980). B. Ricinus cummunis. Discovering Moths: Nighttime Jewels in Your Own Backyard. Cryan (1973) reported an incident in which display of the eyespots appeared to protect a polyphemus in flight from blue jays. Polyphemus caterpillars are never sufficiently common to cause significant damage to their host trees except occasionally in California where they may be pests of commercial plums (Tuskes et al. 1973. When threatened, adult polyphemus flip the front wings forward and also often flap the wings exposing the large hind wing eyespots -- possibly to startle potential predators. Kafatos FC, Williams CM.

Title of Ph.D. Thesis: Genetic study of some life cycle traits of certain phenotypes of muga silkworm ( Antheraea assama Ww) reared on different host plants. The caterpillars of this moth feed on Machilus plant (Machilus bombycina). Therefore, they are short-lived. Muga silkworm (Antheraea assama): It also belongs to the family saturnidae and semi-domesticated in nature. Wagner DL. Quantitative real-time PCR with high-throughput automatable DNA preparation for molecular screening of Nosema spp. The name is because of the large eyespots in the middle of the hind wings.

This report describes the gene coding for golden silk H-fibroin (AaFhc), its expression, full-length sequence and structurally important motifs discerning the underlying genetic and biochemical factors responsible for its much sought-after properties. Some eggs of moths among the Sphingidae, Saturniidae, and Citheroniidae (Lepidoptera). 2000: Low temperature preservation of seed cocoons for delaying moth emergence in muga silkworm (Antheraea assama Westwood). Adults: The adult wingspan is 10 to 15 cm (approximately 4 to 6 inches) (Covell 2005). Caterpillars exposed to short photoperiods (8-12 hours) produce diapausing (overwintering) pupae while those exposed to long photoperiods ( >17 hours) produce non-diapausing pupae (Mansingh and Smallman 1967). Adults have vestigial mouthparts and do not feed. 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. 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. Insect Biochemistry 3: 31-43. Antherea assamensis Helf., Antherea mejankori Moore) belongs to the Phylum-Arthropoda, class- Insects, order-Lepidoptera and family-Saturniidae. Volume 11: 1-477. 1965.

The scoli are orange to red, and the lateral aspects of the dorsal and sub-dorsal scoli are silver. 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. 1975. 512 pp. The translucent yellowish-green to green, full-grown (fifth instar) caterpillars are 60 to 75 mm in length (Godfrey et al. In the West, Native Americans sometimes fill the cocoons of polyphemus and other silk moths with sand or pebbles to make rattles by tying them to sticks or to their ankles for use as musical instruments (Himmelman 2002).

Multi-voltine races found in tropical areas have the shortest life cycle with the egg, larval, pupal and adult stages lasting for 9-12 days, 20-24 days, 10-12 days and 3-6 days, respectively. Camden, Maine. 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. Adult female polyphemus moth, Antheraea polyphemus (Cramer)(dorsal view). Volume 17 of Arthropods of Florida and Neighboring Land Areas. Worth (1980) has designed a tether for this purpose that prevents the tethered moth from escaping or twisting the tethering line around its body.

Adult moth: The adult Bombyx moths do not take any food and incapable to fly. The name is because of the large eyespots in the middle of the hind wings. An elegant harness for tethering large moths. Supplement 30. The family name Saturniidae is based on the eyespots of some members of the family that contain concentric rings reminiscent of the planet Saturn (Powell 2003). Both induction and termination of diapause also may be influenced by temperature (Mansingh and Smallman 1971). Tuskes et al. There is considerable variation in color of the wings even in specimens from the same locality (Holland 1968). Cocoon of polyphemus moth, Antheraea polyphemus (Cramer) with emergence hole. Princeton University Press. The detailed study on ultra-structure of disporous N. bombycis in both the sexes of B. mori along with their development in the life cycle stages of silkworms with special reference to the inoculum concentration of spore is discussed.

Figure 11. 2007. First instar larva of polyphemus moth, Antheraea polyphemus (Cramer). Washington, D.C. Brown SG, Boettner GH, Yack JE. Special Publication Number 12. 1964. The dark bands are spun silk from the inner portions of the cocoons. Urease activity in the feces of larvae reared on mulberry leaves was 30 % of that found in mulberry leaves, while the urease activity could not be detected in the feces of larvae reared on an artificial diet. The dark area of the anal plate extends as a line part way across abdominal segment nine. Peduncle may be weak allowing cocoon to fall to ground during winter or strong so that cocoon remains on tree all winter. After sometime moths emerge from the cocoon, male and … This includes about 10 days as eggs, 5 to 6 weeks as larvae, 2 weeks as pupa, and about 4 days as adults. Figure 8. (1996).

Because of their ease of rearing (Collins and Weast 1961, Villiard 1975) and large size, polyphemus moths are often reared by amateur enthusiasts and also have been used for numerous physiological studies - particularly for studies on molecular mechanisms of sex pheromone action. 2012. The duration of life cycle was longest during winter i.e December-February (79.85 days) and the shortest being in post-monsoon months i.e September-October (53.63 days). Antheraea yamamai This beautiful silkmoth from Japan produces a yellow-green silk that retains its beautiful coloring after degumming. The role of host plants, temperature, humidity, rainfall, photoperiod and climatic variables on the growth and development of insects have clearly been demonstrated. 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.
