Work on GM mustard is carried out by Proagro.
GM mustard contains two alien genes ('barnase' and 'barstar') isolated from a soil bacterium called Bacillus amyloliquefaciens that enable breeding of high-yielding commercial mustard hybrids.
Pro-Agro has developed this genetically modified mustard that resists glufosinate, it's brand of herbicide.

Certain secretions attract the opposite sex of the same species which are termed Pheromones.
Pheromones are substances that are secreted to the outside by an individual and received by a second individual of the same species.
Many examples exist in animals but their role in humans remains uncertain since adults have no functioning vomeronasal organ, which processes pheromone signals in animals.

DDVP is an insecticide which is having fumigant and penetrant action.
Dichlorvos (2,2-dichlorovinyl dimethyl phosphate, commonly abbreviated as an DDVP) is an organophosphate widely used as an insecticide to control household pests, in public health, and to protect stored products from insects.
It is a contact and stomach insecticide with fumigant and penetrant action. It works on wide range of chewing and sucking pests on a wide range of economically important crops. Fast knock-down effect and kills target pests instantly.

AICRP on pesticide residue started in the year 1984.
AICRP is a scheme of Indian Council of Agricultural Research for the development/testing/identification of technologies through multi-location trials.
The All India Coordinated Research Project (AICRP), a landmark in the history of agricultural research was extended to fruit crops during Fourth Five Year Plan. In this system, both central research institutes and State Agricultural Universities (SAUs) work as a team to find solutions to various problems.

Insect mouthparts are specialized structures adapted to their feeding habits.

Chewing and cutting type mouthparts include strong mandibles used to bite, cut, and grind solid food.

Piercing and sucking type mouthparts resemble needles or straws and are used to suck plant sap or animal blood.

Spotted bollworm (Earias vitella) is a larval pest that bores into cotton bolls, flower buds, and shoots.

It feeds by chewing and cutting plant tissues from the inside after entering the boll.

The larvae do not suck sap or liquid but rather eat the solid internal parts of the cotton boll.

Hence, the spotted bollworm has chewing and cutting type mouthparts, not piercing and sucking type.

Therefore, the correct answer is Option A: Chewing and cutting type.

Podagrionidae wasp family is parasitic on mantid eggs.
The adult Mantidophaga wasp lives out its life on a host Praying Mantis. Then, when a female mantis lays her eggs, the Mantidophaga will place its eggs directly into the foamy ootheca as it is being deposited.

A specialized membrane called 'trophamnion' is found in Polyembryony type of reproduction.
The meaning of trophamnion is a nutritive sheath that sometimes invests the embryonic portion of the insect egg, especially in polyembryonic insects. It is a giant unicellular provisory structure derived from the second polar body and performs both protective and digestive functions.
Polyembryony refers to the splitting of one sexually produced embryo into many offspring, which are genetically identical to each other but distinct from their parent, thus differing from asexual budding.

Locusts belong to the family Acrididae.
Locusts are various species of short-horned grasshoppers in the family Acrididae that have a swarming phase.
Locusts are the swarming phase of certain species of short-horned grasshoppers in the family Acrididae. These insects are usually solitary, but under certain circumstances become more abundant and change their behaviour and habits, becoming gregarious.

Fundulus sp. is an example of Mosquitocidal fish.
Fundulus is a genus of ray-finned fishes in the superfamily Funduloidea, family Fundulidae. It belongs to the order toothcarps, and therein the large suborder Cyprinodontoidei.
Fundulus have evolved to occupy a wide range of aquatic ecosystems, including marine, estuarine, and freshwater, making it a good comparative model system for studying evolutionary divergence between marine and freshwater environments.

Metarrhizium anisopliae fungus is effective on root grubs.
Metarhizium anisopliae is a fungus that grows upon insect host cuticle. It is a fungus that grows naturally in soils throughout the world and causes disease in various insects by acting as a parasitoid.
The disease caused by the fungus is sometimes called green muscardine disease because of the green colour of its spores. The cuticle of the cadaver often becomes red. If the ambient humidity is high enough, a white mould then grows on the cadaver that soon turns green as spores are produced.
