Agricultural Entomology MCQ Question and Answer | Agriculture MCQ Question

Excretion by binucleate cells is found in Strepsipterans.
The Strepsiptera are an order of insects with eleven extant families that include about 600 described species. They are endoparasites in other insects.
Binucleated cells are cells that contain two nuclei. This type of cell is most commonly found in cancer cells and strepsipterans.
Binucleation can be easily visualized through staining and microscopy. In general, binucleation has negative effects on cell viability and subsequent mitosis.

Hindgut of insect is also known as Proctodaeum.
The alimentary canal is a tube, usually coiled, which extends from the mouth to the anus, and consists of three regions that are the foregut, midgut and hindgut.
The foregut is also known as the stomodaeum; the midgut is also known as the mesenteron; and the hindgut is also known as the proctodaeum.

Tongue unit of honeybee consists of 2 galeae of maxillae, 2 labial palpi and flexible hairy glossae.
The honey bee, Apis mellifera ligustica, uses the specialized tongue structured by ∼120 segmental units, coated by bushy hairs, to dip varying concentrations of nectar flexibly at small scales.
The tongue unit consists of two galea of maxillae, two labial palpi and elongated flexible hairy glossa of labium. The glossa terminates into a small circular spoon shaped lobe called spoon or bouton or flabellum which is useful to lick the nectar.

Millardia meltada is a Grass rat.
The soft-furred rat (Millardia meltada), or soft-furred metad, is a species of rodent in the family Muridae native to South Asia.
Head and body length is 13 - 16 cm. Yellowish to brownish gray dorsally and whitish in the underparts. Tail naked, blackish above, paler beneath. Fine dense fur shorter ventrally. Males are larger.
It inhabits tropical and sub-tropical forests and grasslands, also making use of irrigated croplands and other cultivated areas.

The scientific name of pink boll worm Pectinophora gossypiella.
The pink bollworm is an insect known for being a pest in cotton farming. The adult is a small, thin, gray moth with fringed wings. The larva is a dull white caterpillar with eight pairs of legswith conspicuous pink banding along its dorsum.
The pink bollworm is native to Asia but has become an invasive species in most of the world's cotton-growing regions. It was a major pest in the cotton fields of the southern California deserts.

The main characteristic feature of an insect is three pairs of legs.
Insects are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae.
The anterior segment, closest to the head, is the prothorax, with the major features being the first pair of legs and the pronotum. The middle segment is the mesothorax, with the major features being the second pair of legs and the anterior wings. The third and most posterior segment, abutting the abdomen, is the metathorax, which features the third pair of legs and the posterior wings.

Hamula is found in 3^rd abdominal segment in Collembola.
The organ most often is present in species of Collembola that lives in the upper soil layers where it is used for jumping to avoid predators.
While at rest, it is retracted under the abdomen and held there by a structure variously called the retinaculum or hamula, which in turn is located beneath the third abdominal segment.

Central honeybee research station is situated in Pune.
The coordinating centers of the Project started functioning at different locations under the Project Coordinating unit located at the then Central Bee Research Institute (CBRI), Pune, presently designated as Central Bee Research & Training Institute (CBRTI), Pune to coordinate, counsel and monitor the activity of the cooperating centre.

The Father of host plant resistance is R. H. Painter.
Host plant resistance is defined as the intentional use of resistant crop cultivars to reduce the negative impacts of pests or diseases on crop production systems.
R. H. Painter is the father of host plant resistance. Host plant resistance means characters that enable a plant to avoid, tolerate, or recover from attacks from insects.

Heat spot is caused by Sitophilus oryzae.
The rice weevil or Sitophilus oryzae is a stored product pest that attacks seeds of several crops, including wheat, rice, and maize.
Larva as well as the adult cause damage to grains. Larvae feed inside the seed and make it hollow and exit by making a circular hole on the surface. Adults can damage several seeds by cutting an irregularly lined circular hole, through which they feed on the kernel.
