1In CHSE Odisha Vocational Sericulture Paper I, sericulture is primarily defined as the commercial culture of which organism for silk?
A.Silkworms for silk production
B.Honeybees for wax only
C.Earthworms for vermicompost only
D.Fish for inland fisheries
Explanation: Sericulture is the rearing of silkworms (and related host-plant culture) to produce silk cocoons and yarn.
2Which silk moth species produces the familiar mulberry silk of commercial reeling industries?
A.Antheraea mylitta
B.Bombyx mori
C.Antheraea assama
D.Samia ricini (Philosamia ricini)
Explanation: Bombyx mori is the domesticated mulberry silkworm; other listed species produce non-mulberry (vanya) silks.
3Voltinism in silkworms refers mainly to which trait?
A.Number of larval legs
B.Length of the silk filament only
C.Number of generations (broods) produced in a year
D.Colour of adult moth wings only
Explanation: Voltinism classifies races as univoltine, bivoltine, or multivoltine by generations per year; the syllabus pairs it with moultinism.
4Moultinism in silkworms describes which of the following?
A.How cocoons are stifled
B.How reeling basins are heated
C.How mulberry is pruned only
D.How many times larvae moult during development
Explanation: Moultinism refers to the number of larval moults (e.g., three-, four-, five-moult races) between successive instars.
5Which pairing of non-mulberry silk and producer is correct?
A.Tasar — Antheraea mylitta; Muga — Antheraea assama; Eri — Samia/Philosamia ricini
B.Tasar — Bombyx mori only; Muga — honeybee; Eri — earthworm
C.All three are produced only by Bombyx mori hybrids
D.Tasar and muga are reeled only from castor plants without moths
Explanation: CHSE practicals require identification of Bombyx, tasar (A. mylitta), muga (A. assama), and eri (Philosamia/Samia ricini).
6Primary host plant of Bombyx mori is:
A.Castor (Ricinus communis)
B.Mulberry (Morus spp.)
C.Terminalia arjuna only
D.Sal (Shorea robusta) exclusively for all races
Explanation: Mulberry silkworms feed on Morus leaves; castor is classic for eri; Terminalia/Shorea hosts are associated with tasar systems.
7Which statement best describes multivoltine silkworm races used commercially in India?
A.They complete only one generation per century
B.They never form cocoons
C.They complete several generations per year and suit tropical continuous rearing
D.They feed exclusively on marine algae
Explanation: Multivoltine races produce multiple broods yearly and are widely used in tropical Indian commercial rearing, often alongside bivoltines and hybrids.
8Bivoltine silkworm races are characterised by:
A.Zero moults and no silk gland
B.Exclusive feeding on oak only in Europe with no Indian use
C.Adult aquatic nymph stages
D.Two generations per year and typically higher silk quality potential than many multivoltines
Explanation: Bivoltines have two generations yearly; Indian programmes often use bivoltine pure races and multivoltine × bivoltine hybrids for quality silk.
9Complete metamorphosis of Bombyx mori proceeds through which sequence?
A.Egg → larva → pupa → adult moth
B.Egg → adult only
C.Larva → adult → egg → pupa (reverse order always)
D.Nymph → imago without pupa (hemimetabolous)
Explanation: Paper III Unit I covers egg, larva, pupa, and moth morphology—classic holometabolous (complete) metamorphosis.
10Larval prolegs and claspers of Bombyx mori are best described as:
A.Adult flying organs homologous to bird wings
B.Structures used with true thoracic legs for gripping the leaf/bed during feeding and movement
C.Silk reeling machine parts
D.Mulberry root nodules
Explanation: Syllabus larval morphology lists mouthparts, legs, prolegs, spiracles, eyes, claspers, and integumentary hair.
