completely unmelanized except for the eye pigments is shown
in Fig. 2h. An albino pupa that died immediately after larval
molting and with cephalothorax deformed is shown in Fig. 2i.
Morphological aberrations were also found among pupae
exposed to the oils (Fig. 3). A dead normal pupa that is brown
in color and otherwise normal in appearance is shown in
Fig. 3a. Figure 3b, c shows pupae with a superficial resemblance of an elephant and is designated “elephantoid.” In
elephantoid pupae, the developing mouthparts are distinctly
separated from the cephalothorax. A dead pupa exhibiting a black pupal form and extended shape is depicted in Fig. 3d.
Figure 3e shows dwarf pupa with retarded abdomen. Figure 3f
shows treated Ae. aegypti which died as deformed pupa. The
wing pads are elongate (arrow), more so than those in a normal pupa. Wing pads were not appressed to the body with
larval appearance at its posterior end. Figure 3g illustrates a
pupa which died with almost complete emergence from the
larval exoskeleton but with the caudal end still attached to the
larval exuvium. In addition, an abnormal pupal stage with
distortion of the digestive tract and posterior abdominal
