Agricultural Entomology MCQ Question and Answer | Agriculture MCQ Question

Honeybees are used for Apiculture.
Apiculture (or Beekeeping) is the maintenance of bee colonies, commonly in man-made beehives. Honey bees in the genus.
The keeping of bees by humans, primarily for honey production, began around 10,000 years ago. Georgia is known as the "cradle of beekeeping" and the oldest honey ever found comes from that country. Bee hives are kept in an apiary or "bee yard".

Surface layer of cocoon is called as Floss.
Floss silk is the filaments from the soft, internal covering of a silkworm cocoon, and in particular from the places where the cocoon is not damaged by the caterpillar. Floss silk is normally classed as a continuous filament. The silk is unravelled off the cocoon, dyed and then made into hanks.
Silk fibroin (SF) is a crystalline protein-based fiber surrounded by layers of the gum sericin protein, which reinforces the cocoon structure, where it is very suitable for the subsequent development and metamorphosis of the matured larvae to pupae.

Sotto disease of the silkworm is caused by Bacteria.
It is caused by toxin of Bacillus thuringensis. The larvae become unconscious, soft, and darkish and rot off.
It is caused by a virus called Morator Virus which does not form polyhedra in the body of silkworm larvae. The infection occurs mainly through oral cavity.

DDT was first of all made by the scientist Zedler.
Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, an organochloride.
DDT was first synthesized in 1874 by the Austrian chemist Othmar Zeidler. DDT's insecticidal action was discovered by the Swiss chemist Paul Hermann Muller in 1939.

Supra oesophagial ganglion is also called Brain.
The supraesophageal ganglion also known as arthropod brain or microbrain is the first part of the arthropod, especially insect, central nervous system. It receives and processes information from the first, second, and third metameres.
The supraesophageal ganglion lies dorsal to the esophagus and consists of three parts, each a pair of ganglia that may be more or less pronounced, reduced, or fused depending on the genus.

In cotton, the serious sucking pest is Leaf hopper.
A leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees.
Aphids that attack the cotton crop are one of the major sucking pests in cotton. These pests suck the liquid from the leaves and cotton boll of small plants and thus restrict the growth of the boll and the plant as well.
Both nymphs and adults suck the sap from the under surface of leaves, tender leaves turn yellow, leaf margins curl downwards and reddening sets in.

The inner core of silk filament, fibrion is a Protein.
Silk fibroin is a protein with intrinsic characteristics that make it a good candidate as a scaffold for tissue engineering.
Silk is a continuous filament fiber produced by silk worms. The raw fiber consists of two filaments glued together with a substance called sericin.

EPN multiplied on the live culture of Galleria mellonella.
Galleria mellonella Infection Model Identifies Both High and Low Lethality of Clostridium perfringens Toxigenic Strains and Their Response to Antimicrobials.
Mechanisms of the anaerobe Clostridium perfringens and associated diseases have been frustrated by the lack of reliable infection models.

A. Rice weevil ⇔ Sitophilus oryzae
Sitophilus oryzae is also called Rice weevils. These insects are cosmopolitan in distribution and have originated in Far East region. They can exist anywhere where physical conditions for growth are favourable and the grain is left undisturbed for some time.
B. Pulse beetle ⇔ Helicoverpa armigera is not correctly matched.
The pulse beetle, scientifically known as Bruchus chinensis, is a serious pest of stored food grains and causes damage to cowpea, gram, soybean, and pulses. This pest is distributed worldwide and is commonly found in India.
C. Lesser grain borer ⇔ Rhizopertha dominica
Rhyzopertha dominica, is known commonly as the lesser grain borer, American wheat weevil, Australian wheat weevil, and stored grain borer. It is a beetle commonly found within store bought products and pest of stored cereal grains located worldwide.
D. Khapra beetle ⇔ Trogoderma granarium
The khapra beetle (Trogoderma granarium), also called cabinet beetle, which originated in South Asia, is one of the world's most destructive pests of grain products and seeds. It is considered one of the 100 worst invasive species in the world.

Citrus nematode females are Cocci shaped.
Tylenchulus semipenetrans, also known as the citrus nematode or citrus root nematode, is a species of plant pathogenic nematodes. Their feeding strategy is semi-endoparasitic and has a very narrow host range among commonly grown crops.
The posterior end of the female citrus nematode becomes swollen upon feeding. She contains a single ovary and the vulva is subterminal. The female will lay up to 100 eggs deposited in a gelatinous matrix secreted from the nearby excretory pore. The pore is surrounded by small, irregularly shaped lobes; and the excretory duct is directed forward.
