Wermelinger, Eduardo D.;Zanuncio, José C.;Rangel, Elizabeth F.;Cecon, Paulo R.;Rabinovitch, Leon;
Anais da Sociedade Entomológica do Brasil , 2000, DOI: 10.1590/S0301-80592000000300025
Abstract: a study was conducted to compare the susceptibility of third instar larvae of lutzomyia longipalpis (l. & n.) (diptera: psychodidae: phlebotominae), the vector of the american visceral leishmaniasis to two strains of bacillus thuringiensis serovar israelensis, one strain of bacillus sphaericus (all pathogenic to diptera culicidae) and a strain of b. thuringiensis ser. morrisoni (pathogenic to larvae of anticarsia gemmatalis (hübner) (lepidoptera: noctuidae)). larvae of l. longipalpis showed similar susceptibility to the two strains of b. thruringiensis ser. israelensis, while b. sphaericus and b. thuringiensis ser. morrisoni showed low and no larvicidal effect to this vector, respectively.

Abstract: this is the first record of immature stages of species belonging to the subgenus nyssorhynchus (blanchard) in eutrophized breeding habitats. larvae of anopheles (nys.) evansae (brethes), anopheles (nyssorhynchus) rangeli (gabaldon et al), culex nigripalpus (theobald) and culex quinquefasciatus (say) (diptera: culicidae) were collected in a rural eutrophized dam in rio de janeiro state, in southeastern brazil. eutrophication was substantiated by the low diversity of mosquitoes, the high incidence of cx. quinquefasciatus (42%) and of daphinia sp. and, the high levels of both organic nitrogen (0.28 mg/l) and total phosphorus (0.02 mg/l).

Abstract: euselasia eucerus (hewitson, 1872) (lepidoptera: riodinidae) is a brazilian native species commonly found in eucalyptus plantations. biotic mortality factors of this defoliator were studied in a eucalyptus urophylla plantation in minas gerais state, brazil aiming to identify natural enemies and their impact on this insect. euselasia eucerus had biotic mortality factors during all development stages. the most important were trichogramma maxacalii voegelé and pointel, 1980 (hymenoptera: trichogrammatidae) during egg stage (48.9%), a tachinid fly (diptera: tachinidae) during larval stages (10%) and itoplectis sp. (hymenoptera: ichneumonidae) during pupal stage (52.2%). the parasitism rate was higher in the basal part of the plant canopy (37.8%).

Abstract: this work investigated the potential of tyrophagus putrescentiae (schrank) (astigmata: acaridae) to control lasioderma serricorne (f.) (coleoptera: anobiidae) in the laboratory. l. serricorne is the most destructive insect pest ever found on stored tobacco. the experimental delineation had 33 arenas being each experimental unit with 11 arenas of experiments with eggs, larva of l. serricorne with the density of t. putrescentiae maintained constant, where from 11 of these arenas, eight were for the analysis of predation and three to evaluate the natural mortality of the insect. the highest predation rate was found during the larval stage with, approximately, 54, 68 and 78% mortality of l. serricorne from the fourth until the sixty day of predation. these results indicated that it was possible to use the predatory mite t. putrescentiae in pest management programs of l. serricorne in the storage units of tobacco.

Abstract: egg viability and nymphal development of the predatory bug supputius cincticeps (st?l, 1860) were evaluated during two generations in the biological control laboratory of the núcleo de biotecnologia aplicada à agropecuária (bioagro/ufv) in vi?osa (minas gerais, brazil) at 24.72±1.10oc and photophase of 12 hours. three treatments were represented by s. cincticeps fed with zophobas confusa gebien, 1906, tenebrio molitor linnaeus, 1758 and musca domestica linnaeus, 1758 larvae. higher egg viability of this predator was found when the preys were z. confusa and t. molitor, 74.46% and 80.91 %, than in m. domestica, 57.02%, but incubation period showed no differences between preys. shorter nymphal development and higher nymphal viability were found with z. confusa and t. molitor than with m. domestica. higher weight increase was found for nymphs which originated males and females in the second generation specialy with the first two preys.
Development of Lutzomyia intermedia and Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae) larvae in different diets
WERMELINGER, E. D.;ZANUNCIO, J. C.;
Brazilian Journal of Biology , 2001, DOI: 10.1590/S1519-69842001000300009
Abstract: the objective of this research was to evaluate, in laboratory, the development of lutzomyia intermedia and lutzomyia longipalpis (diptera: psychodidae: phlebotominae) larvae, vectors of leishmaniasis in brazil, in the following diets: industrialized food for rabbits, dogs, hamsters and aquarium fishes, besides liver powder, cooked lettuce, wheat germ, beer yeast, oat, wheat bran and a diet denominated aged food. except wheat bran for l. intermedia, all diets provided adequate development for both species, which showed that any of them can be used in laboratory insectaries for these insects. l. intermedia showed better development with most nutritious diets and both species presented better development with aged food. fungi as an additional nutrient source for l. intermedia and l. longipalpis is suggested.

Abstract: nymphs of podisus nigrispinus (dallas, 1851) were fed with zophobas confusa gebien, 1906, tenebrio molitor linnaeus, 1758 (coleoptera, tenebrionidae) and musca domestica linnaeus, 1758 (diptera, muscidae) under 25±0.5oc, 60±10% of rh and photophase of 12h. nymphal viability of p. nigrispinus were 64.0%, 80.0% and 92.0% with z. confusa, m. domestica and t. molitor, respectively. no differences were found for pre-oviposition period, number of egg masses, number of eggs, egg viability, and longevity for females of this predator fed with any of these preys.

Abstract: the morphology of the reproductive tract of podisus nigrispinus (dallas) females fed with alabama argillacea (hübner) larvae, artificial diet, tenebrio molitor l. larvae or musca domestica l. larvae were studied. the reproductive tract of females of this species presented yellow coloration and independent of the diet, each ovary had seven ovarioles joined through terminal filaments and forming a bunch shape structure. the histological data revealed that the ovary of p. nigrispinus was of meroistic telotrophic type, with each individual ovariole divided in a terminal filament, a tropharium (trophic chamber), a vitellarium, and a pedicel. the prey type affected the development and morphometry of these structures. females of p. nigrispinus fed with 3rd or 5th instar larvae of cotton leafworm (a. argillacea) presented developed ovaries with ovarioles showing a great number of oocytes in advanced stages of development. females fed with artificial diet presented atrophic ovaries and ovarioles practically without oocytes. females fed with t. molitor or m. domestica showed ovaries in intermediary stage of development. the central ovariole was longer in females fed with 5th instar larvae of cotton leafworm and shorter in those fed with artificial diet. most developed oocytes were observed in ovaries of females fed with 5th or 3rd instar larvae of cotton leafworm, and the majority of atrophic oocytes were found in females fed with artificial diet.

Abstract: attack behavior of the predator podisus rostralis (st?l) (heteroptera: pentatomidae) adults on fourth instar bombyx mori l. (lepidoptera: bombycidae) caterpillars was studied in laboratory conditions. ten 24 hours old adults of this predator were observed during two hours with the following attack behavior: (1) predator: prey finding; prey observation; touching prey with antenna; attack behavior; prey paralysis; predator retreat after attack; attack cessation; successive attacks; and (2) prey: defense. the predator p. rostralis found its prey before attacking and it approached it with slow circular movements. the attack was usually made in the posterior part of the prey to reduce defense reaction. larger size of prey in relation to the predator resulted difficult prey paralysis but it occurred in less than two hours.
