1. ‘NABIO808’ (Syn. ‘NAROBAN5’): A tasty cooking banana cultivar with resistance to pests and diseases
Abstract ‘NABIO808’ is a newly released, conventionally-bred triploid cooking banana cultivar in Uganda. It produces an average bunch yield of 54.5 t ha-1 yr-1 and is resistant to weevils, nematodes, and black Sigatoka. Additionally, its food is yellow, soft, and tasty, like that of most preferred landrace cultivars, making it more acceptable to end-user

2. Boll weevil within season and off-season activity monitored using a pheromone-and-glue reusable tube trap
ABSTRACT: The boll weevil colonizes cotton fields as early as cotton squaring, causing significant losses due to feeding and protected development inside fruiting structures throughout crop phenology. Successful control depends on control of adults and their accurate detection when they colonize the crops. The commercial trap and boll weevil attract-and-cont

3. (1R,2S,6R)-Papayanol, Aggregation Pheromone of the Guava Weevil, Conotrachelus psidii
Comparative GC/MS analysis of airborne volatiles produced by males and females of the guava weevil Conotrachelus psidii (Coleoptera: Curculionidae: Molytinae) showed the presence of a malespecific electroantennographically active compound identified as (1R,2S,6R)-2-hydroxymethyl-2,6- dimethyl-3-oxabicyclo[4.2.0]octane (papayanol). Release of this compound wa

4. Epistasia na herança da resistência do milho ao gorgulho Sitophilus zeamais (Coleoptera: Curculionidae) / Epistasis in the inheritance of maize resistance to Sitophilus zeamais (Coleoptera: Curculionidae)
Considerado um dos aspectos mais complexos da genética quantitativa, a epistasia tem sido ignorada pelos melhoristas nos estudos de herança dos caracteres, principalmente os da herança da resistência de plantas a insetos, que são de difícil obtenção. No milho, a principal praga de grãos é o Sitophilus zeamais (Coleoptera: Curculionidae), devido a s

5. Interação entre fungos toxigênicos (Aspergillus flavus e Fusarium verticillioides) e carunchos (Sitophilus zeamais) em amostras de grãos de milho. / Interaction between toxigenic fungus (Aspergillus flavus e Fusarium verticilliodes) and weevils (Sitophilus zeamais) in samples of maize grains.
The weevils Sitophilus zeamais ability was examined to propagate spores of Aspergillus flavus and Fusarium verticillioides and the production of mycotoxins. Corn grains was conserved in flasks connected by a rubber to form a closed system (side A and B) and divided in six groups: G1 (corn + weevil - side A); G2 (corn + A. flavus - side A); G3 (corn + A. flav

6. Phylogenetic analysis and systematic revision of the genus Anchylohynchus Schoenherr, 1836 (Curculionidae: Derelomini), using discrete and continuous morphological characters / Análise filogenética e revisão sistemática do gênero Anchylorhynchus Schoenherr, 1836 (Curculionidae: Derelomini), com o uso de caracteres morfológicos contínuos e discretos
Recently, phylogenetic analysis based on continuous characters was made accessible. This increases the pool of characters available for morphology-based phylogenetic analyses, but there is still no consensus on how this kind of characters should be coded and analyzed. In the present study, I assessed the use of continuous characters in phylogenies from two d

7. Biosprospecção de extratos vegetais e sua interação com protetores de grãos no controle de Sitophilus zeamais Mots. (Coleoptera: Curculionidae) / Bioprospecting of plant extracts and their interaction with grain protectans in the control of Sitophilus zeamais Mots. (Coleoptera: Curculionidae)
Objetivou-se, no presente estudo, avaliar a ação de extratos orgânicos e frações de plantas com atividade inseticida, bem como, a associação de extratos orgânicos brutos com terra de diatomácea no controle de Sitophilus zeamais Mots. (Coleoptera: Curculionidade), em milho armazenado. Os extratos foram obtidos por meio de maceração em solventes org

8. Carunchos VS inseticidas: individualidade importa? / Maize weevils VS inseticides: does individuality matters?
Behavior is the expression of an organism s interactions with the environmental stimulus. Even though behavioral studies are done in an individual level, the conclusions are drawn for populations. The importance of an individual s behavior have been studied on several animal groups, a few examples are: primates, mammals and insects. From these results, the c

9. Alternative food sources and overwintering feeding behavior of the boll weevil, Anthonomus grandis boheman (coleoptera: curculionidae) underthe tropical conditions of central Brazil
The boll weevil causes serious damage to the cotton crop in South America. Several studies have been published on this pest, but its phenology and behavior under the tropical conditions prevailing in Brazil are not well-known. In this study the feeding behavior and main food sources of adult boll weevils throughout the year in Central Brazil was investigated

10. Feromônios de agregação em curculionidae (insecta: coleoptera) e sua implicação taxonômica
The pheromones of the weevils has been the most studied and used so far for Coleoptera species. The majority of reported weevil pheromones is produced by males and usually attract both sexes. The identified pheromone compounds are classified in two categories: ten-carbon compounds with terpenoid branching and compounds of various sizes, apparently of fatty-a

11. OCCURRENCE AND BIOECOLOGIC ASPECTS OF SOYBEAN ROOT WEEVILS / OCORRÊNCIA E ASPECTOS BIOECOLÓGICOS DOS CURCULIONÍDEOS-DAS-RAÍZES EM SOJA [Glycine max (L). Merryl]
The objective of this study was to evaluate the population fluctuation and the distribution of the soybean root weevils (Coleoptera: Curculionidae), and the population fluctuation was determined in a soybean area in the period December, 2006 to November, 2007, in the Restinga Seca county, RS. Distribution in space and time was evaluated in a soybean experime

12. Ciclo biológico, comportamiento y censo del picudo del camu camu, Conotrachelus dubiae O'Brien 1995 (Coleoptera: Curculionidae) en Pucallpa, Perú
Camu camu weevil Conotrachelus dubiae O'Brien, 1995 is a one of the main pests of camu camu (Myrciaria dubia H.B.K. Mc Vaugh) in Peruvian Amazonia. The aim of this study was to determine the biological cycle of this insect under laboratory conditions, to describe its behavior and population numbers under field conditions in Pucallpa, Ucayali, Peru.
