Table III. It is obvious from the data in Table III that the housefly and the mosquito, in both the adult and larval stage, are susceptible to insecticides of the DDT type. However, the extravagant claims that DFDT is far superior to DDT as a contact insecticide against flies are not borne out by the results of controlled laboratory tests. The Peet-Grady testing technique used by Prill (92) would indicate that in the presence of added pyrethrins DDT is definitely superior to DFDT when applied as a spray. On the other hand, DFDT gave higher percentage kills than DDT when flies were placed under a Petri dish and held in contact with deposits of the compounds on glass surfaces. A comparison of the activity of these compounds against adult mosquitoes has not been reported.

Amhros In the cki mutant, where the cells divide in the middle of the second larval stage, they seem to divide without losing their tri-potent capacity. In the cki mutant we just double the number of cells. 

A mbros Reasonably well. The basic mechanism is translational regulation of Lin-14 mRNA. lin-4 is a small antisense RNA which accumulates towards the end of the first larval stage and binds to the 3bUTR of lin-14 mRNA, inhibiting LIN-14 translational elongation.

The term dauer stage is perhaps more appropriate since this type of dormancy is not restricted to the larval stages but has been observed in the... 

Fig. 9.1. Transmission electron micrographs of parasitic nematode cuticles in transverse section. The structurally distinct layers and the underlying hypodermal syncytia are indicated. Nematodes depicted are the infective larval stage of the canid parasite Toxocara canis and the fourth larval stage of the human filarial parasite Brugia malayi.

The hatching of the first larval stage of filarial nematodes, the microfilaria (mf), from the eggshell is quite different from the process in other...
