| The aim of this study was to verify the viability of exclusive use of elephant grass pollen, Pennisetum purpureum (Schum), to feed larvae of the lacewing Chrysoperla externa (Hagen, 1861). The insects were kept at 24ºC and the duration and survival rate of each instar and the larval and pupal phases were recorded. The diet provided complete development of the larvae. The average duration of the first and second instars was the same (6.9 days), while the third instar lasted an average of 10.0 days and the pupal phase 13.2 days. The average survival of the larvae was above 80% for the first, second and third instars, and 70.0% and 33.3% for the larval and pupal phase, respectively. These results indicate that the exclusive use of elephant grass pollen can... |

| The objective of this work was to compare the biology of Chinavia impicticornis and C. ubica (Hemiptera: Pentatomidae), two species of stinkbugs that occur as secondary pests in soybean. Life table procedures were used for evaluating nymphs, and fecundity tables for evaluating adults, in order to establish the demographics of the two species. The two species have similar demographic parameters, and the development of immature stages, from egg to adult, had similar duration periods of approximately 30 days. In both species, eggs and second-instar nymphs were the stages with higher mortality. Total egg production did not differ between females of both species. Fecundity and survival curves for adults showed similar trends in both species. However, C. ubica... |

| Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 ± 1°C), RH (60 ± 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean and peanut seeds and privet Ligustrum lucidum Ait. fruit (Oleaceae)]. All three artificial diets allowed full development. The diet containing sunflower oil was the most suitable for N. viridula while E. heros developed better on a diet composed of soybean oil. Data indicated that the artificial diets were inferior to the natural diet. The artificial diets were more adequate for... |

| Eggs of Anagasta kuehniella (Zeller 1879) are widely used for mass rearing of Trichogramma spp. and other parasitoids and predators, largely commercialized in many countries. The aim of this study is to evaluate the effect of carbon dioxide (CO2) originated from larval metabolism on the biological parameters of A. kuehniella. For that purpose, we assess the production of carbon dioxide (CO2) per rearing tray of A. kuehniella and the effect of CO2 on the viability of egg-to-adult period and oviposition of A. kuehniella. Results allow to estimate that a rearing tray, containing 10,000 larvae between the 4th and 5th instars, produces an average of 30.67 mL of CO2 per hour. The highest egg production of A. kuehniella was obtained when the larvae were kept in... |

| The objective of this work was to determine the fecundity of the predator Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) females of two weight classes aiming to define, which one presented higher productivity in the laboratory. Males and females of B. tabidus were reared from nymphs fed with Tenebrio molitor L. (Coleoptera: Tenebrionidae) pupae in laboratory. Females of B. tabidus weighting 95 to 150 mg and those with 160 to 220 mg constituted two treatments. Oviposition period and numbers of egg masses, eggs and nymphs per female of B. tabidus were higher in the treatment with heavier females, while the periods of preoviposition, between egg mass laying, egg incubation and number of eggs per egg mass, besides the percentage of nymphs hatched... |

| Thyrinteina arnobia, is one of the most important defoliating caterpillars of Eucalyptus in Brazil The objective of this work was to evaluate the development and the reproduction of feeding on leaves of guava (Psidium guajava) or Eucalyptus grandis in the 15th generation, after rearing this species for 14 genrations on guava leaves. T. arnobia showed shorter larval period, better viability of caterpillars and pupae, heavier pupae, higher number of eggs per female, better egg viability and shorter longevity of females in guava leaves than in Eucalyptus leaves. The better development and reproduction with P. guajava showed that this insect could be reared in laboratory with guava leaves. |

| A reprodução de parasitóides apresenta etapas interligadas e a idade de hospedeiros e parasitóides pode afetar o desenvolvimento desses últimos. Características biológicas de fêmeas de Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae), com até 96 horas de idade, foram estudadas em pupas do hospedeiro alternativo Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae). Cada pupa de A. gemmatalis com 0-24, 24-48, 48-72 ou 72-96 horas de idade, foi oferecida ao parasitismo por 10 fêmeas de T. diatraeae com 0-24, 24-48, 48-72 ou 72-96 horas de idade, por 24 horas à 25 ± 2oC, umidade relativa de 70 ± 10% e fotofase de 14 horas. A emergência, o número de descendentes, a duração do ciclo, a razão sexual, a longevidade e largura da cápsula... |

| Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae) is a gregarious and polyphagous parasitoid mainly of Lepidoptera pupae. The objective of this paper as to study the developent of parasitoid on Bombyx mori L. (Lepidoptera: Bombycidae) pupae exposed to one, nine, 18, 27, 36, 45 or 54 female P. elaeisis, respectively. The females of the parasitoid remained in contact with pupae for 24 hours in glass tubes (14.0 x 2.2 cm), packed in a climatic chamber regulated at 25 ± 2°C, 70 ± 10% relative humidity and photo phase of 12 hours. With the exception of density 1:1 (72.72%), in other densities parasitism was 100%. Adults of P. elaeisis did not emerge from pupae at densities of 1:1 and 9:1, but 100.0% of parasitoid emergence was observed at the... |
