MCQ (Single Correct) +4 −1
English हिन्दी
Insects belonging to hemotrophous group are:
हीमोट्रोफस (Hemotrophous - रस/द्रव पोषी एवं एफिडभक्षी) समूह से संबंधित कीट कौन से हैं?
EXPLANATION Biological Control: Predators, Parasitoids (Trichogramma, Bracon), Hyperparasitoids and Conservation

Nutritional guild classification in insect families:

  • Family Syrphidae (hoverflies / flower flies, Order Diptera): The larvae of the subfamily Syrphinae are obligate predators of soft-bodied hemipterans (primarily aphids, scale insects, and psyllids), feeding by grasping the prey, piercing the cuticle, and imbibing the body fluids/hemolymph (hemotrophic / aphidophagous liquid feeding).
  • Formicidae: Ants (omnivorous social hymenopterans).
  • Cerambycidae: Longhorn beetles (xylophagous wood-boring larvae).
  • Noctuidae: Phytophagous foliage-feeding lepidopteran larvae.
Hence, Syrphidae belongs to the hemotrophous predatory group.

कीट कुलों की पोषण संबंधी विशेषताएं:

  • कुल सिरफिडी (Syrphidae - होवरफ्लाई): डिप्टेरा गण के अंतर्गत सिरफिडी के लार्वा (मैगट) एफिड्स और रस चूसक कीटों के शरीर में छिद्र कर उनके आंतरिक द्रव और हीमोलिम्फ को चूसते हैं (हीमोट्रोफस / एफिडभक्षी द्रव पोषण)।
  • फॉर्मिसिडी: चींटियां (सर्वाहारी सामाजिक कीट)।
  • सिराम्बीसिडी: काष्ठ छेदक बीटल (जाइलोफेगस)।
  • नॉक्टुइडी: वनस्पतिभक्षी इल्लियां (शाकाहारी)।
अतः सही उत्तर सिरफिडी (Syrphidae) है।
