Given below are two statements Statement (|); The term"... | Agrigyan

• Mass Production of Trichogramma Egg Parasitoids:
• Laboratory Host: In India, bio-control laboratories and commercial facilities mass-produce egg parasitoids (Trichogramma chilonis, T. japonicum, T. brassicae) exclusively on the eggs of the rice moth, Corcyra cephalonica (family Pyralidae).
• Trichocards: Eggs of Corcyra cephalonica are glued to cards (Tricho-cards), UV-sterilized to prevent host emergence, exposed to Trichogramma adults for parasitization, and dispatched for release against lepidopteran borers in sugarcane, cotton, and rice.
• Conclusion: Exclusively mass-produced on (B) Corcyra cephalonica only (Option 4).

Correct option: (4) (8) only,

• Forensic Acarology and Corpses:
• Demodex: Demodex folliculorum and Demodex brevis are microscopic arachnids (mites) that inhabit human hair follicles and sebaceous glands. In forensic science, postmortem examination of facial follicles and tissues reveals Demodex densities and degradation status, assisting in postmortem interval (PMI) estimation.
• Other Genera: Tetranychus and Eriophyes are exclusively phytophagous plant pests; Otobius is the spinose ear tick of livestock.
• Conclusion: Demodex is associated with forensic science on human corpses (Option 3).

Correct option: (3) Demodex

• Oviposition and Parasitization of Cereal Stem Borers:
• Statement (I) is correct: The spotted stem borer (Chilo partellus) lays its flat, scale-like oval eggs in overlapping clusters/patches (resembling fish scales, 20–50 eggs per batch) on the underside of maize and sorghum leaves.
• Statement (II) is correct: Eggs of the pink stem borer (Sesamia inferens) laid beneath the leaf sheath are heavily parasitized by scelionid egg parasitoid wasps (genus Telenomus, family Scelionidae).
• Conclusion: Both Statement (I) and Statement (II) are correct (Option 1).

• Scale Insects (Coccidae) Characteristics:
• Pair-by-Pair Matching:
• Brown soft scale $\rightarrow$ (IV) Coccus: Coccus hesperidum is the cosmopolitan brown soft scale attacking citrus and greenhouse ornamentals.
• Black scale $\rightarrow$ (III) Saissetia: Saissetia oleae is known worldwide as the black scale of olive, citrus, and deciduous fruit crops.
• Yellowish white soft scale $\rightarrow$ (II) Ceroplastes: Ceroplastes floridensis / C. rubens secrete thick yellowish-white or pinkish wax coatings.
• Chocolaty nymphs, females with white mealy substance $\rightarrow$ (I) Parasaissetia: Parasaissetia nigra (nigra scale) exhibits shiny dark brown-black chocolaty adult scales.
• Correct Choice: Option 4 maps (A)-(IV), (B)-(III), (C)-(II), (D)-(I).

Correct option: (4) (A) - (IV), (B) - (ND, (€) - (), (B) - (0)
