Agricultural Entomology MCQ Question and Answer | Agriculture MCQ Question

Uricotelism refers to the excretion of Urates and Urea.
Ureotelism occurs when the major urinary excretory product is urea, whereas amino-ureotelism occurs when the major urinary excretory products are both ammonia and urea.
Urea is highly water soluble and difficult to concentrate; therefore, it must be excreted with significant amounts of water.

Nutritional studies are carried out by use of Cockroaches.
Cockroaches are an important source of food for several organisms, including arthropods, birds, and mammals. As such, they are an important part of the food chain. Cockroaches also play an extremely important role in nutrient cycling.
Cockroach contains protein crystals that contain a considerable amount of energy, much higher than that found in dairy milk from cows. The proteins are also packed with a large number of essential amino acids, which are good for muscle repair.

Phoridae is known as 'Humpbacked flies'.
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking to the wing.
This family, also known as humpbacked flies and scuttle flies (4000 species), is another group that exploits a wide range of habitats and exhibits diverse feeding habits.

Wasp venom contains Serotonin.
Wasp venom share several biologically active proteins and neurotransmitters, such as phospholipases A₂ and B, hyaluronidase, serotonin, histamine, dopamine, noradrenaline and adrenaline.
These proteins can cause type 1 hypersensitive reactions ranging from local skin irritation to anaphylactic shock. Furthermore, the toxins can cause direct organ injury or delayed hypersensitivity reactions.

Homomorphism is seen in Cowbug and Membracidae.
Homomorphism is a similar appearance of two unrelated organisms or structures without an actual relationship, in structure or origin.
The family Membracidae, is a group of insects related to the cicadas and the leafhoppers. These may be serial homologues of insect wings, which are dorsal appendages of the second and/or third thoracic segments.

Corpora codiaca secretes the Hormone in insect.
The neurosecretory cells and the corpus cardiacum, a transformed ganglion closely associated with the heart, produce a peptide, called the prothoracicotropic hormone (PTTH), which stimulates the prothoracic gland to produce ecdysone, a sterol hormone.
CC is the major neurohemal organ in insects and releases a large number of neuropeptides.

The Father of Acridology is Uravov.
Sir Boris Petrovitch Uvarov was a Russian-British entomologist best known for his work on the biology and ecology of locusts. He has been called the father of acridology.
Acridology is the scientific study of grasshoppers and locusts.

Brocap trap is used for Coffee berry borer.
The BROCAP trap combined with additional pest management can increase yield by up to 12%.
The particularity of this pest is that the female beetle bores into the coffee berries, lay eggs and then the entire life cycle of the larvae occur within the berry, which can cause entire harvests to be destroyed.

In rice, clipping of tip seedlings before transplanting is done to eliminate egg masses of Yellow stem borer.
Clipping of rice tips to reduce the infestation of stem borer and alley ways for BPH in paddy.
Sri. J. Vijay demonstrated cutting the tips of paddy seedlings before transplanting, egg masses laid by paddy stem borer are destroyed and reduce the infestation of stem borer ahead.

Woolly aphid is the pest of Peach.
Woolly apple aphid is a serious pest of peaches and apples, particularly young trees. Colonies form at wound sites on trunks, limbs, and twigs, where they feed on tender bark.
Pruning and hail damage can create wound sites for attack by this pest. Egg-laying wounds by the periodical cicada are ideal sites for infestation.
