Quantitative data are given on the preovipostion, oviposition, incubation and premoult periods of Amblyomma hebraeum Koch maintained in darkness at 26ï¿½C and 90% RH; the duration of feeding in all stages on laboratory hosts and the onset of pharate development in engorged larvae and nymphs were also examined. Sexual maturation, mating capacity and longevity of parasitic males and mate-seeking in relation to engorgement in females have been studied.
Bregmencyrtus gen. nov. is descriptionbed for the Madagascan Eucomys durantae Risbec, 1958 and Lombitsikala coccidivora Risbec, 1957, also from Madagascar, is redescriptionbed and compared with Discodes Foerster and Trichomasthus Thomson. Xenocomys Blanchard, 1940 is synonymized with Neococcidencyrtus Compere, 1928 and Microterys pudaspidis Annecke is transferred to the latter genus as a new combination. A key is given to the descriptionbed species of Neococcidencyrtus.
The equipment and methods used in the successful rearing of myrmecophilous stages of Lepidochrvsops methymna methymna (Trimen) and L. trimeni (Bethune-Baker) are descriptionbed. Details are given of the formicarium used to house a colony of the host ant Campanatus maculatus (Fabricius) and of the methods employed in establishing and maintaining the ants and in introducing the lycaenid larvae to them.
Data are given on the rate of feeding and quantity of nutrient imbibed by all stages of Amblyomma hebraeum Koch. Growth of testes and the progress of spermatogenesis in the males has been studied in relation to feeding. The ultrastructure of primary spermatocytes has been examined.
The preoviposition period of Boophilus decoloratus was studied under laboratory and field conditions and found to be temperature dependent. Humidity effects on the duration of the preoviposition period were found to be negligible. Some of the problems associated with analysing the effects of two interacting physical factors such as temperature and humidity on the biological responses ofticks are discussed. Female ticks placed in a Stevenson's screen in the field demonstrated very long preoviposition periods and the biological implications of this are discussed.
