The au-thors are also grateful to the three anonymous reviewers for their valuable comments for im-proving the quality of the work. Moreover, an attempt was made to induce feeding on an artificial diet fortified with the chemicals by the early instar larvae to test their efficacy. AW Significant variation of soluble protein, total phenol, and PAL activity was observed in the leaves of four host plants at three different maturity levels. 2006). To confirm the role of different phenolic compounds, sterols, and essential oils, attraction, biting and feeding tests were conducted with standard chemicals. ML Hazarika (Neog et al. A non-parametric binomial test was used to deter-mine significant differences between the numbers of larvae choosing different plants through odor perception. Smith Presence of higher levels of soluble protein, myrcetin and 7, 2′, 4′ trimethoxy dihydroxy flavone, and PAL enzyme activity can be used as biochemical markers for selecting host plants with leaves of different age groups. 2005). NM A higher mortality rate among early instars was observed when the larvae were fed with mature leaves. M be host plants, two species, Persea bombycina King ex. The two plants food choice test (dual choice test) was carried out between a host plant, P. bombycina or L. polyantha and a non-host, L. grandifolia or Z. jujuba. As per our studies using SEM, the maxillary palp of A. assamen-sis contains eight sensilla basiconica in a groove and, similar to other Lepidopterans (Dethier and Crnjar 1982), three out of them located centrally,with a unique grooved struc-ture are olfactory, and five located peripherally, each with a small terminal pore, are gustatory (unpublished data). . Thus, in wild habitat, host plant chemicals play key roles in orientation and food selection through the participation of the antenna and maxillary palp in A. assamensis. producing an exquisite and lustrous golden yellow silk of high economic value. host plant of Muga silkworm (Antheraea assamensis Helfer) Neog K1*, Das A1, Unni BG2, Ahmed GU3 and Rajan RK1 1Central Muga Eri Research & Training Institute, Central Silk Board, Lahdoigarh, Jorhat, Assam;India. Schoonhoven The larvae of Antheraea mylitta are polyphagus and can take leaves of several host plants like Arjun, Asan, Ber, Sal, Jam, Sidha, etc. Schroeder The feeding habits of Antheraea assamensis, Helfer (Lepidoptera: Saturniidae) larvae towards the leaves of its four different host plants, Persea bombycina King ex. Pracros The authors are grateful to Dr. R.K. Rajan, Director, CMER&TI, Jorhat, Assam, India, and Director, NEIST (CSIR), Jorhat, Assam, India, for their encouragement and for providing the laboratory facilities necessary to complete the work. Six Petri plates were arranged for each diet as in the above experiment. Translations are not retained in our system. The results of the present study suggest that, out of leaves of different host plants belonging to Lauraceae family, the newly hatched A. assamensis were mostly attracted by the medium leaves of P. bombycina compared to all other leaves of different age groups. Rose Bernays (2011) showed a mixture of caryophyllene, decyl aldehyde, and dodec-ylaldehyde to be attractive for biting behavior of A. assamensis larvae. In the case of A. assamensis, although β-sitosterol's effect on biting behavior is greatly reduced, the compound's effects become pronounced when it is combined with phenolics. When preference for a host plant was studied by us-ing one plant choice test, 70–100% of both ANT and MAX larvae preferred P. bombycina over water. Rearing of Antheraea assamensis Heifer (Muga) on Persea bombycina King (Som) and Litsea polyantha Blume (Soalu), the two primary host plants, is prerogative of Assam for commercial production of golden yellow Muga silk. Hence, when the larvae were exposed to the odor of L. polyan-tha, they could not recognize L. polyantha on first exposure as their host.

Insects use various sensory systems to locate their hosts (Chapman 2003; Bullas-Appleton et al. Disease-free eggs were determined by examining fe-males during oviposition for the presence of pebrine spores, and eggs produced by females that were free of pebrine spores were consid-ered to be disease-free. This preference may vary widely among different host plants of the same family or even among different varieties of the same species (Lederhouse et al. The muga silkworm, Anthereae assamensis Helfer feeds on a wide range of The feeding habits of Antheraea assamensis, Helfer (Lepidoptera: Saturniidae) larvae towards the leaves of its four different host plants, Persea bombycina King ex. 1997). The filter paper disk containing the extract of the host plant was kept in one chamber (adapter), and the disk containing the extract of the non-host plant was kept in the other chamber, so that the insect could perceive the odor moving along the airflow. Larvae fed with diet 20 reached the maximum 2nd instar larval weight (0.103 g), followed by those fed with diet 10 (0.100 g). Hazarika Gabler Kataky Medium leaves were mostly preferred as revealed by the feeding behavior and survival rate of the larvae during different instars. Twenty newly hatched larvae were allowed to feed on different leaf types that were reared up to spinning. . MP Both Were Competent In Rejecting The Non-Hosts , L. Grandifolia And Z. Jujuba. Attraction and feeding tests with detached leaves and artificial diet with different chemical stimulants revealed that a mixture of the flavonoids, myrcetin, and 7, 2', 4' trimethoxy dihydroxy flavone with sterol compound β-sitosterol elicited the most biting behavior by A. assamensis larvae. . Muller Family-Lauraceae) is the primary host plant of golden silk producing muga silkworm (Antheraea assamensis Helfer), which is effected by one of the major foliar diseases grey blight caused by the fungus Pestalotiopsis disseminata (Thum) Stey. CE Muga silkworm, Antheraea assamensis Helfer (Lepidoptera: Saturniidae), the producer of golden silk, is a lepidopteran insect endemic to northeastern India. Following the incubation for 45 minutes at 32° C, an absorbance of 290 nm was measured after the reaction was stopped with the addition of 1M TCA. 2Department of Biotechnology, North East Institute of Science and Technology, Jorhat, Assam;India. It is found in Assam in northeast India where 99% of its production occurs.. G (2007) showed the stronger preference of a monophagous Chrysomelid beetle for its host plant to be based on contact cues rather than on odor cues. The freshly prepared ex-tracts of leaves were applied to 1 × 1 cm pieces (Whatman No. Hook (Laurales: Lauraceae), Litsea polyantha Jussieu.L. Corio-Costet Create a new folder below.

Christensen A chi-square test was per-formed between the percent of choosing larvae to show orientation preference. JJA You have requested a machine translation of selected content from our databases. Arora & Gupta (1979) recorded the following host-plants for Indian assamensis: Cinnamomum, Laurus, Litsea, Persea (Lauraceae); Magnolia, Michelia (Magnoliaceae); Quercus (Fagaceae); Sarcostemma (Asclepiadaceae); Symplocos … G Larvae were given a choice between host, P. bombycina, and non-host, L. grandifolia. Many specialists on the angiosperms Rutaceae, Magnoliaceae, or Monimiaceae maintained the ability to detoxify the Lauraceae (Scriber et al. Hamamura et al. Rowel (1992) observed highest survival rates and first instar growth rates for P. troilus on Lindera benzoin and P. palamedes on Persea borbonia. In plant-eating insects where larvae develop on a single host, the ovipositional behavior of adult females determines the larval habitat (Gothard et al. Abstract. 2005). Caryophyllene, decyl aldehyde, dodecyl aldehyde also showed a highly positive response, but a mixture of all three yielded the highest attraction response (99%). JN Its other host plants include Actinodaphnae obovata Nees (Blume), A. anquistifolia (Blume) Nees, Cinnamomum glaucescans (Nees) Drury, C. glanduliferum (Wallich) Meisner, Litsea nitida (Roxburgh) Hooker f., all of which belong to Lauraceae family. The total number of mature larvae that survived out of total larvae brushed during the early stage (1st and 2nd instar), middle stage (3rd and 4th instar) and mature stage (5th instar) was recorded and statistically analyzed. JR JH Phytophagous insects show varying degrees of association with host plants, a particular plant species or group of plants on which they feed (food plant range) (Unni et al.

JJA Induction of feed-ing preference by diet was earlier reported in M. sexta (De Boer 1992). Anthereae assamensis Helfer can be taken up on both the food plants while for seed crop rearing should be conducted on soalu plants irrespective of seasons. Muga silkworms showed attraction towards filter papers treated with citral and linalool, but maximum attraction was acheived by linalyl acetate alone, a chemical that attracted more silkworms than a mixture of all three.
