[Biologic effect of diflubenzuron on Blattella germanica (Dictyoptera: Blattellidae)].

The Amejeiras strain of Blatella germanica (Dictyoptera: Blattellidae) kept in lab conditions since 1994 and susceptible to arpocarb, malathion and cipermethrin insecticides, was studied. This strain was treated with 4 diflubenzuron (Dimilin OMS 1804) concentrations supplied by feeding nymphs at their first stage of development, with the purpose of determining their effect on the survival, phenotype and period of nynmphal development of this species. The dosage-mortality line of regression was determined and the values of CE50 = 0.042% and CE95 = 0.357% were obtained. Sublethal effects were observed in the nymphs treated with the 4 tested concentrations whereas the morphogenetic effects in adult insects only occurred when they were exposed to higher concentrations (0.25% and 0.4%). The nymph development stage showed a highly significant increase when the diflubenzuron concentration was raised. (F = 11.64; p < 0.001).

[Comparison of 3 methods for collecting adult anophelines in a risk area of malaria transmission].

Three methods of collecting adult anophelines were comparatively studied in a rural town in Havana Province, during the period comprised between June and September 1986. The methods of capture used were as follows: in resting sites, in human bait and through lactic acid CDC light traps. A greater number of anophelines (F = 6.86; p less than 0.01) was collected on human bait. The capture of 11 species of culicines was reported.

[Hematophagous activity of Anopheles vestitipennis Dyar & Knab, 1906 (Diptera: Culicidae)].

The hematophagic activity of Anopheles vestitipennis Dyar and Knab, 1906, was studied in a rural locality during the dry and rain seasons, through inside and outside home collects with human bait at a schedule form 19:00 to 07:00 hours. The species showed preference by inside home food (endophagic) in both seasons. There was 2 maximum activity peaks inside of the buildings, from 23:00 to 24:00 hours and from 02:00 to 03:00 hours (the first one agrees with the peak occurring outside). During the dry season the activity peak outside occurred from 24:00 to 01:00 hours; while inside occurred from 02:00 to 03:00 hours.
