Mean percent consumption, total consumption, and choice indices were used as parameters for drawing conclusions. The foods used were two hosts, two non-hosts, and a neutral medium (water). Both antennae and maxillary palpi were fully competent in preference for host plants, Persea bombycina Kostermans (Laurales: Lauraceae) and Litsea polyantha Juss, over the non-hosts, Litsea grandifolia Teschner and Ziziphus jujuba Miller (Rosales: Rhamnaceae). Both were competent in rejecting the non-hosts, L. grandifolia and Z. jujuba. The odor choice test was carried out using a Y-tube olfactometer and showed similar results to the ingestive tests. The results indicate the necessity of functional integration of a combination of olfactory and gustatory sensilla present in different peripheral organs in food acceptance by A. assamensis larvae.</p>10afood choice10amaxillae10aY-tube olfactometer1 aBora, Dipsikha, S.1 aDeka, Bhabesh1 aSen, Avolikiteswar  uhttps://library.ncl.res.in/content/host-plant-selection-larvae-muga-silk-moth-antheraea-assamensis-and-role-antenna-and-001806nas a2200217   4500008004100000022001400041245012400055210006900179260006700248300001200315490000700327520100300334653001601337653001001353653002101363653001101384100002301395700001801418700002301436856012901459       2016                        eng d  a1738-229700aRestricted diet breadth of the larvae of antheraea assamensis and the role of the labrum-epipharynx and galeal sensilla0 aRestricted diet breadth of the larvae of antheraea assamensis an  a111 RIVER ST, HOBOKEN 07030-5774, NJ USAbWILEY-BLACKWELLcMAR  a128-1380 v463 a<p>The silkworm, Antheraea assamensisHelfer (Lepidoptera: Saturniidae), grows primarily on Persea bombycina and Litsea polyantha. To understand if the restricted diet breadth is due to the specific role of gustatory sensilla of the larvae of A.assamensis, the same fifth instar larvae retaining only labrum-epipharynx or galeal sensilla were subjected to food choice tests. The foods used were leaves of two host-plant and two non-host-plant species. Mean per cent consumption and per cent of choosing larvae were used as parameters for drawing conclusions. The finding indicated involvement of the labrum-epipharynx for acceptance and galeal sensilla for rejection of a non-host-plant species. Scanning electron microscope studies revealed the presence of two sensilla on the galea, one lateral and one medial sensilla styloconicum and two gustatory sensilla in the epipharynx of A.assamensis. The study revealed the key role of galeal sensilla in the restrictive diet-breadth of A.assamensis.</p>10afood choice10agalea10agustatory organs10alabrum1 aBora, Dipsikha, S.1 aDeka, Bhabesh1 aSen, Avolikiteswar  uhttps://library.ncl.res.in/content/restricted-diet-breadth-larvae-antheraea-assamensis-and-role-labrum-epipharynx-and-galeal
