Agricultural Entomology MCQ Question and Answer | Agriculture MCQ Question

Chlorpyriphos methyl + deltamethrin is Storicide II.
Storcide II (chlorpyrifos-methyl + deltamethrin) is registered for use on small grains (barley, oats, rice, sorghum and wheat).
Storcide II is targeted as the replacement product for Reldan 4E and the original Storcide. It is effective against a broad spectrum of stored grain pests, including lesser grain borer.

Safest chemical for honey bees is Endosulphan.
Endosulfan is an off-patent organochlorine insecticide and acaricide that is being phased out globally. It has been used globally as a pesticide since the 1950s to control a variety of insects including whiteflies, aphids, leafhoppers, Colorado potato beetles, and cabbage worms.
Endosulfan was very much safer for honeybees than the two organophosphate insecticides.

A. Endosulphan ⇔ Thiodan
The trade name of endosulphan is Thiodan. Endosulfan is an off-patent organochlorine insecticide and acaricide that is being phased out globally. It has been used in agriculture around the world to control insect pests.
B. Chlorpyrifos ⇔ Dursban
Dursban is the common trade name, but it is one product of more than 800 containing the chemical chlorpyrifos. Chlorpyrifos is commonly found in many home-and-garden bug sprays. It is used in some treatments of termites. And it is used on some crops.
C. Dimethoate ⇔ Rogor
The trade name of Dimethoate is Rogor. It is a systemic insecticide with the added advantage of contact action to give a rapid kill of insect pests hit by the spray at time of application. It controls aphids and several other insect pests on a wide range of horticultural and crops.
D. Phorate ⇔ Nuvacron is not correctly matched.
The trade name of Phorate is AC 8911, Agrimet, Geomet, Granutox, Phorate 10G, Rampart, Terrathion, Thimenox, Thimet, Timet, Vegfru and Vegfru Foratox.

Host evasion is a type of resistance that comes under Ecological resistance.
Ecological resistance is resistance related to favourable environmental conditions at a given location at a particular time.
Host evasion occurs when a host passes through the susceptible stages very quickly or during a period when pests are fewer.

Pitfall trap is used for Ground beetles, Collembola and Spiders.
Pitfall trap is a simple device used to catch small animals. A hole in the ground into which a bucket or pipe is placed into the soil so that the mouth is level with the soil surface.
These traps are often used to capture small mammals, reptiles and frogs that fall into the pit and cannot escape due to the smooth walls.

The anticoagulant that is used for rat control is Warfarin.
Warfarin is a synthetic derivative of dicoumarol, and since 1948 has had a major role in slaughtering rats and mice by stimulating internal bleeding.
It was the first anticoagulant rodenticide. It was registered for use in 1950. Warfarin was discovered in moldy sweet clover that had made a herd of cattle sick.

Tandem copulation is found in Odonata insect order.
The male will either remain in direct contact or reside nearby to defend the female while she lays her eggs. ‘Contact guarding’ occurs when the male remains physically attached to the female in the tandem position.
Males that contact guard has greater security against other males trying to mate with the female as it is much more difficult for another male to grab a female that is already in tandem. The tandem position may, however, present a larger target for potential predators such as lizards and birds.

Silver fish belonging to the order Thysanura.
The silverfish (Lepisma saccharinum) is a species of small, primitive, wingless insect in the order Zygentoma (formerly Thysanura). Its common name derives from the insect's silvery light grey colour, combined with the fish-like appearance of its movements.
The silverfish is a nocturnal insect typically 13 - 25 mm (0.5 - 1.0 in) long. Its abdomen tapers at the end, giving it a fish-like appearance.

Insect vector of African sleeping sickness (caused by Trypanosoma gambiense) is Tse-tse flies.
African Trypanosomiasis, also known as “sleeping sickness”, is caused by microscopic parasites of the species Trypanosoma brucei. It is transmitted by the tsetse fly (Glossina species), which is found only in sub-Saharan Africa.
The tsetse fly, Glossina sp. is the main vector for trypanosomes, the parasites that cause trypanosomiasis. This disease affects both humans and livestock.

Dorsum of insects containing meso and meta notum is called Alinotum.
Alinotum is the plate to which the wings are attached on the notum of an insect.
The pterothoracic nota (comprising the meso- and metathoracic segments) have two main divisions that are the anterior wing-bearing alinotum and the posterior phragma-bearing postnotom.
The mesothorax and metathorax have become so intimately associated with the wings that they have almost become a subunit separate from the prothorax, and as such the two segments combined are often referred to as the pterothorax.
