Example text

The branching of the setae increases with subsequent instars, as does the number of comb scales. In genera other than Anopheles and. Aedes, the last instar is easily recognized by the saddle that completely encircles the anal segment. " The last instar of thase Aedes that do not have a completely encircling saddle may be recognized by the position of the saddle seta l-X, which arises closer to the posterior margin of the saddle than to its ventral margin (Smith 1969a, 1969b)" In all second and third instars, the saddle seta arises at, or very close to, the ventral margin of the saddle, often in the membrane ventral to the saddle.

The maxillary body has an anterior lobe that bears a dense apical tuft of setae and a posterior lobe fringed with shorter setae. Each of the three thoracic segments and the first seven abdominal segments are partly encircled laterally by a transverse row of paired, symmetrically irranged setae. Each pair of setae is typically numbered from 0 to 14, beginning with the one closest to the middorsal line and ending with the one neirest the midventral line. Some setae have migrated from their usual positions and therefore are difficult to number.

Place the terminalia in a solution of NaOH (l pellet in 20 mL of water) and heat just to the boiling point for 5-10 min. Remove the terminalia in the solution from the heat and while the solution is still hot draw l-2 cm3 of it into a hypodermic syringe, pin down the end of the abdomen with the point of the needle, and with the orifice of the needle directed away from the terminalia eject the contents of the syringe. The terminalia may burst if the stream of solution is directed into the terminalia, but when it is directed away from it, any partly dissolved tissues are pulled by cutting 52 out by suction.
