Agricultural Entomology MCQ Question and Answer | Agriculture MCQ Question

The process of pushing the ventral surface of nematode embryo into the interior is known as Epiboly.
Epiboly describes one of the five major types of cell movements that occur in the gastrulation stage of embryonic development of some organisms. It is the spreading and thinning of the ectoderm while the endoderm and mesoderm layers move to the inside of the embryo.

Newton hive is best suited for Apis cerana type of honey bee species.
A smaller beehive called a Newton hive is used for Apis cerana. It is constructed in the same way with ten frames in each chamber, but the dimensions of both hive and frames are smaller than those of the Langstroth hive, as is appropriate for the smaller bees.
Apis cerana, the eastern honey bee, Asiatic honey bee or Asian honey bee, is a species of honey bee native to South, Southeast and East Asia.

Electrodyne sprayer was discovered by Coffee.
Electrodyne sprayer project water, and are used to kill weeds and destroy pests. By applying fertilizers, pesticides, and herbicides on crops electrodyne sprayers contribute to crop health and quality.
A programme the investigation was started in mid-1977 in Spain into the performance of the 'Electrodyn' sprayer for the control of insect pests on cotton.

Painted bugs belong to the species Bagrada cruciferorum.
Bagrada hilaris is a species of shield bug known by the common names bagrada bug and painted bug. It could be mistaken for or erroneously referred to as harlequin bug.
The adult bug is 5 to 7 millimeters in length, shield-shaped, and black with white and orange markings. The female, which is larger than the male, lays up to 100 oval or barrel-shaped eggs on leaves or in the soil beneath plants.
The eggs are white when freshly deposited and turn orange over time. Within 8 days the first-instar nymph emerges. It is bright orange-red and turns darker as it develops, becoming black by the last instar.

In gram, circular bore holes on pods plugged by the head of a larva are related to Gram pod borer.
The caterpillars feed on buds, flowers, grains, fruits, pods; sometimes leaves and stems. In grams, they attack foliage and consume developing seeds.
The greatest damage is caused to cotton, tomatoes, maize, chick peas, alfalfa and tobacco.

Phylum-Mollusca is divided into Six classes.
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks.
The phylum is typically divided into six taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates and either the giant squid or the colossal squid is the largest known invertebrate species.
The gastropods (snails and slugs) are by far the most numerous molluscs and account for 80% of the total classified species.

The following order closely related to Glossata is Trichoptera.
Trichoptera, or caddisflies, are an order of aquatic insects occurring around the world in rivers, streams, and lakes. About 15,000 species are known. The aquatic larvae use silk to construct cases in which they reside or to spin silken nets to capture food suspended in the water column.
Larvae of members of the family Glossosomatidae in the suborder Spicipalpia create dome-shaped enclosures of silk which enables them to graze on the periphyton, the biological film that grows on stones and other objects, while carrying their enclosure around like turtles.

Although body wall exhibits bilateral symmetry in nematode, yet stylet knobs exhibit Tri-radiate symmertry.
Tri-radiate means having three rays or radiating branches.
The tri-radiate condition would be explained if the dorsal hydrocoele formed only a single podium and ambulacrum.

V. M. Stern proposed the concept and terminologies of 'Bioeconomics'.
Bioeconomics is a progressive branch of social science that seeks to integrate the disciplines of economics and biology for the sole purpose of creating theories that do a better job of explaining economic events using a biological basis and vice versa.
Vernon Mark Stern (28^th March 1923 - 16^th March 2006) was an American professor of entomology at the University of California, Riverside considered one of the founding figures of integrated pest management. He also developed the concept of economic injury level and other economic thresholds about which he wrote an influential review paper in 1973.

Scientifically lac insect is known as Laccifera lacca.
The Indian lac (Laccifer lacca), a South Asian scale insect, secretes a resin material onto trees that can be used as shellac, an important ingredient in various inks, paints, sealants and varnishes.
The life cycle of this scale insect proceeds with the first instar of the larval stages, which are known as "crawlers". Larvae in this stage crawl along the branches of their host plants and feed on the phloem.
