MCQ (Single Correct) +4 −1
The size (mm) of a healthy adult Laccifer lacca ranges between:
एक स्वस्थ वयस्क लाख कीट (Laccifer lacca / Kerria lacca) का आकार (मिमी) किसके बीच होता है?

Body size of the lac insect, Kerria lacca (Laccifer lacca):

  • Adult females are globular, degenerate, wingless, and measure approximately 4 to 5 mm in body dimensions inside their protective resinous encrustation.
  • Adult males measure about 1.2 to 1.5 mm (winged or apterous), while early crawling nymphs measure ~0.5 to 0.6 mm.
  • reflects the keyed answer in the examination.

लाख कीट (Kerria lacca) में वयस्क मादा का शारीरिक आकार लगभग 4 से 5 mm होता है, जबकि नर कीट 1.2 से 1.5 mm तथा प्रारंभिक क्रॉलर लार्वा 0.5-0.6 mm के होते हैं। NTA उत्तर कुंजी अनुसार विकल्प 2 सही है।
