Figure 2. Effects of DFB on molting, egg-laying and hatching of T. castaneum.

Figure 2

Larvae and adults were fed with a flour-brewer’s yeast diet containing 100 ppm DFB. Whereas particularly younger larvae were significantly impaired by DFB, adults did not exhibit any increase in mortality when compared with control insects. Death was observed during the larval-to-larval molts (A, B), the larval-to-pupal molt (C), and the pupal-to-adult molt (D). Note that the larval spiracles are melanised extensively (B). Adults were not affected by DFB (E). Oviposition and subsequent embryonic development appeared to be normal after DFB treatment of adult females (G). However, egg-hatch was completely inhibited by DFB treatment and the development was arrested (F).
