एलीगेटर खरपतवार को एगैसिकल्स हाइग्रोफिला द्वारा नियंत्रित किया जा सकता है, जो है -

Fungi कवक Flea beetle फ्ली बीटल Scale insect स्केल कीट Bacteria बैक्टीरिया

Agasicles hygrophila (the alligator weed flea beetle) is a chrysomelid beetle utilized as an exceptionally successful classical biocontrol agent against Alternanthera philoxeroides.

Fungi: Classical fungal mycoherbicides include Colletotrichum gloeosporioides (Collego).
Flea beetle: Agasicles hygrophila belongs to the beetle family Chrysomelidae (flea beetles), feeding voraciously on alligator weed foliage and stems.
Scale insect: Dactylopius tomentosus was used for controlling prickly pear cactus.
Bacteria: Xanthomonas campestris pv. poannua is an example of a bacterial bioherbicide.

Hence, the correct option is (B).

एगैसिकल्स हाइग्रोफिला (Agasicles hygrophila) एक फ्ली बीटल (भृंग) है, जिसका उपयोग एलीगेटर खरपतवार (Alternanthera philoxeroides) के जैविक नियंत्रण में किया जाता है।

कवक: कवक जनित बायो-हर्बीसाइड को माइकोहर्बीसाइड कहते हैं (जैसे कॉलेगो)।
फ्ली बीटल: यह क्राइसोमेलिडी कुल का कीट है जो पत्तियों और तनों को खाकर खरपतवार को नष्ट करता है।
स्केल कीट: डेक्टाइलोपियस कीट का उपयोग नागफनी के नियंत्रण में किया गया था।
बैक्टीरिया: यह जीवाणु नहीं है।

अतः सही विकल्प (B) है।
