“…Otros reguladores como el dimilín (difluobenzurón o TH-6040) y otros ecdisoides son venenos que actúan selectivamente en los insectos, bloqueando los mecanismos de la écdisis o muda. Estos productos, además de su elevado costo, presentan otras limitaciones porque no penetran con facilidad la cutícula del insecto y, por tanto, no han encontrado aplicación práctica en el control de insectos (19). El Bacillus thuringiensis var.…”

In order to begin mass producing the nematode Romanomermis iyengari Welch, a bioprocessing plant was designed and set up on the grounds of Universidad Federal in the State of Roraima, Brazil, after reaching an agreement with the State's Health Department. The objective of this paper was to establish the basic process for mass breeding the parasite in order to apply it to anopheline breeding sites. Cultures were obtained at a rate of 68 during every seven-day cycle, making for a total of 272 cultures a month. Before treatments were applied in the field, laboratory tests were conducted that showed the great susceptibility of anopheline larvae to infestation by R. iyengari, with parasitism rates ranging from 71 to 98%. In order to assess the parasitizing capacity of R. iyengari in actual field conditions, 12 natural anopheline breeding sites were chosen, each ranging in size between 50 and 450 m2. The species Anopheles albitarsis Lynch-Arribálzaga and Anopheles rondoni Neiva-Pinto were detected there, at densities that ranged from 34 to 66 larvae/m2. The biolarvicide was sprayed in all 12 breeding sites with a domestically manufactured pump set at a pressure of two atmospheres and a dose of 2,000 preparasites/m2. Seven days after treatments were performed, anopheline populations were markedly reduced (85 to 97%). Results obtained point to the feasibility of using R. iyengari to control larval populations of both species of anophelines.

The effect of the juvenile hormone analogue Altosid SR 10 was carried out on some species of culicine mosquitoes and associated insects under field and laboratory conditions. In laboratory, Altosid SR 10 gave direct toxic effect against larvae, prolonged larval and pupal periods, inhibited adult emergence and disturbed the sex ratio of Culex pipiens molestus (Forsk). In the field, Altosid SR 10 exhibited toxic effect against larvae and inhibited adult emergence of C. pipiens molestus, Theobaldia longiareolata (Macq.) and the rat tailed larvae Eristalis sp. The compound had no effect on the beneficial aquatic beetle Dytiscus sp. Zusammenfassung Zur Wirkung des Juvenilhormon‐Analogen Altosid auf einige Stechmückenarten (Dipt., Culicidae) und auf mit ihnen assoziierte Insekten unter Freiland‐ und Laborbedingungen Untersuchungen mit Altosid SR 10 ergaben im Labor toxische Wirkungen auf die Larven sowie Verlängerungen der Larven‐ und Puppenentwicklung, Hemmungen des Adultenschlüpfens und Störungen des Geschlechterverhältnisses von Culex pipiens molestus. Im Freiland zeigte Altosid SR 10 eine Giftwirkung auf die Larven sowie eine Hemmung des Adultenschlüpfens von C. pipiens molestus, Theobaldia longiareolata und der Larven von Eristalis sp. (Rattenschwanzlarven). Dagegen wurden nützliche Wasserkäfer (Dytiscus sp.) von der Verbin‐dung nicht beeinflußt.

“…The biological effects of synthetic analog of juvenile hormone on a variety of insects have been well documented despite the fact that the mode of action of this hormone is not fully understood. Lethal effects of such an analog, or mimic, on the metamorphosis of mosquitoes were previously described (Spielman and Williams 1966;Spielman and Skaff 1967;Ittycheriah et al 1974). In Aedes aegypti female sexual receptivity was induced precociously by the topical application of a JH mimic (Gwadz et al 1971).…”

THE EFFECTS OF A JH MIMIC AND CAUTERIZATION OF THE CORPUS ALLATUM COMPLEX ON THE MALE ACCESSORY GLANDS OF AEDES AEGYPTI (DIPTERA: CULICIDAE)

Juvenile hormone, the secretion of the corpus allatum, apparently controls the secretory process of the male accessory glands of the yellow fever mosquito, Aedes aegypti. Topical application of a juvenile hormone mimic induces precocious and enhanced secretion. The treatment with the JH mimic not only increases the potency of males to inseminate more numbers of females, but also stimulates secretion in fully depleted glands of A. aegypti which under normal conditions do not renew the secretory process. Males whose accessory glands are depleted due to multiple matings and later treated with the mimic also inseminate. Cauterization of the corpus allatum complex has prevented the secretory function in the glands.
