Biology of nymphs of Rhodnius robustus Larrousse, 1927 (Hemiptera, Rreduviidae), fed on pigeon or on swiss mouse blood in laboratory conditions BJB
BRAGA,M. V.; PRATA,K. C.; BRAZIL,R. P..
The duration of the life cycle of Rhodnius robustus Larrousse, 1927 as well as the mortality rate of each nymphal instar were studied comparing groups fed on pigeon or on mouse blood weekly or fortnightly. This species showed a better development and lower mortality rate when fed on swiss mouse. The intervals between feedings apparently did not have influence on the shortening of the cycle. We suggest that laboratory colonies and experiments with R. robustus are better maintained when these triatomines are fed on swiss mouse.

Effect of sodium silicate application on the resistance of wheat plants to the green-aphids Schizaphis graminum (Rond.) (Hemiptera: Aphididae) Neotropical Entomology
Basagli,Marco A.B.; Moraes,Jair C.; Carvalho,Geraldo A.; Ecole,Carvalho C.; Gonçalves-Gervásio,Rita de C.R..
The green-aphid Schizaphis graminum (Rond.) is considered the major important pest of wheat plant, for causing severe injuries to the plants in all phenological crop stages, being able even to cause plant death. The objective of this study was to evaluate the effects of the application of silicon on the resistance of wheat plants to this pest. The experiments were carried out under greenhouse and laboratory conditions. The greenhouse experiment was conducted in a completely randomized experimental design with two treatments, consisting on silicon application and a control (without silicon application) with 10 replications and without environmental control. The laboratory bioassays were conducted under controlled environmental conditions (25 ± 1°C...

Herbivory on bracken (Pteridium spp.) by Bolax palliata Burmeister (Coleoptera: Scarabaeidae), a poliphagous beetle of the Venezuelan Andes Neotropical Entomology
Avila Núñez,Jorge L.; Otero,L. Daniel; Naya,Marlene; Calcagno-Pisarelli,Maria P..
Herbivore attack by Bolax palliata Burmeister is reported on two sympatric bracken species: Pteridium caudatum (L.) Maxon and P. arachnoideum (Kaulf.). Laboratory and field observations revealed a preference for the last of the two species. Available phytochemical information suggests it could be based on differences in concentration of condensed tannins.

Immature stages and phylogenetic importance of Astrapaeus, a rove beetle genus of puzzling systematic position (Coleoptera, Staphylinidae, Staphylinini) Naturalis
Pietrykowska-Tudruj, E.; Staniec, B.; Wojas, T.; Alexey, A..
For the first time eggs, larvae and pupae obtained by rearing are described for Astrapaeus, a monotypic West Palearctic rove beetle genus of a puzzling phylogenetic position within the megadiverse tribe Staphylinini. Morphology of the immature stages of Astrapaeus ulmi is compared to that of other members of the tribe and discussed in a phylogenetic context. Contrary to conventional systematics and in accordance with recently developed phylogenetic hypotheses based on morphology of adults, larval morphology supports the non-Quediina affiliation of Astrapaeus. Eggs and pupae provided fewer characters with putative phylogenetic signal. Under laboratory conditions, a peculiar preference for isopod prey was observed for A. ulmi. However, this could not be...

Preferência alimentar de adultos de Metriona elatior Klug (Coleoptera: Chrysomelidae, Cassidinae) por diferentes híbridos de Solanum melogena Linnaeus (Solanaceae) - DOI: 10.4025/actascibiolsci.v30i4.5874 Biological Sciences
Al Gazi, Ariel David Freitas; UNESP/Jaboticabal; Gandolfo, Daniel; ARS/Argentina; Pitelli, Robinson Antonio; UNESP/Jaboticabal.
Metriona elatior Klug é potencial candidato para o controle biológico de Solanum viarum Dunal (joá-bravo), pois as larvas e adultos se alimentam de suas folhas e têm baixa taxa de dispersão. A especificidade é um forte requisito para a adequabilidade de um organismo como agente de controle biológico, especialmente pela estratégia inundativa. Desse modo, a preferência alimentar do adulto desse inseto em laboratório foi avaliada em 14 híbridos de Solanum melogena Linnaeus (berinjela). A criação estoque foi mantida em laboratório, com os indivíduos se alimentando de folhas do joá-bravo. O estudo foi realizado utilizando-se testes de dupla e múltipla escolha, em períodos de alimentação de 24 e 48h, oferecendo-se discos de tecido foliar, em condições de placas...

Response of the galling insect Aciurina trixa Curran (Diptera: Tephritidae) to host plant quality Anais da SEB
Fernandes,Geraldo W.; Price,Peter W.; Gonçalves-Alvim,Silmary J.; Craig,Timoty P.; Yanega,Douglas.
Female host plant selection, oviposition behavior, and offspring performance of the gall-forming tephritid Aciurina trixa Curran (Diptera: Tephritidae) on NPK-fertilized and control plants of Chrysothamnus nauseosus hololeucus Pall. (Britton) (Asteraceae) were studied in northern Arizona, USA. There was no statistically significant difference in the proportion of females that selected control versus fertilized plants, and between the time to accept control versus treatment plants. Females laid fewer eggs and spent a longer time ovipositing on control plants than on treatment plants. Larval performance (measured as time of first gall appearance on plant, gall diameter, and larval weight) was not statistically different between fertilized and control plants...

Shredders prefer soft and fungal-conditioned leaves, regardless of their initial chemical traits Iheringia, Sér. Zool.
Biasi,Cristiane; Cogo,Gláucia B.; Hepp,Luiz U.; Santos,Sandro.
ABSTRACT Through field and laboratory experiments we investigated the effects of leaf traits of two tree species and microbial conditioning on the abundance, biomass, and feeding preference of a typical macroinvertebrate shredder. In the field, we compared the association of Phylloicus (Calamoceratidae, Trichoptera) with two tree species commonly found in riparian zones, which are representative of high and low nutritional quality, respectively: Nectandra megapotamica and Chusquea tenella. In the laboratory, we investigated the feeding preference of Phylloicus using unconditioned leaves and leaves conditioned by aquatic fungi. The same tree species used in the field experiment were used in the laboratory. Initially, C. tenella leaves were proved to be more...

Within plant distribution of Anthonomus grandis (Coleoptera: Curculionidae) feeding and oviposition damages in cotton cultivars Ciência e Agrotecnologia
Grigolli,José Fernando Jurca; Souza,Leandro Aparecido de; Fraga,Diego Felisbino; Funichello,Marina; Busoli,Antonio Carlos.
The feeding and oviposition behavior of boll weevil in new cotton cultivars is essential for an adequate management. The objective of this study was to evaluate the vertical distribution of squares punctured for feeding and oviposition of the pest in the cultivars NuOPAL, DeltaOPAL, FMT-701, FMX-910 and FMX-993, and record the most and least preferred times of feeding and oviposition. The number of squares used for boll weevil feeding and oviposition were evaluated weekly in three parts of plant canopy. It was observed that, regardless the cultivar, A. grandis preferred to lay eggs in squares located in the upper part and feed on squares in the middle and upper parts. The boll weevil preferred to feed on cultivar FMT-701 in the beginning of the period of...
