Size thrips larvae
Size of thrips larvae
The size of thrips larvae was measured using a binocular microscope with an ocular graticule. We measured length, width and height of ten small first-instar larvae (freshly hatched from eggs), ten large first-instar larvae (about to molt into second instar larvae), ten small second-instar larvae (just molted from first instar) and ten large second-instar larvae (about to molt into prepupae) Thrips larvae were measured on a cucumber leaf in a Petri dish (as described above for the thrips culture); length and width were measured with the Petri dish in a horizontal position, height was measured with the Petri dish in a vertical position.
