1. Metabolomic and Histological Response of Passiflora cincinnata Infected with Cowpea aphid-borne mosaic virus (CABMV) Reveals Changes in Asymptomatic and Symptomatic Phases
Passion fruit woodiness disease, caused by the Cowpea aphid-borne mosaic virus (CABMV), is one of the leading phytosanitary challenges of passion fruit production. Passiflora cincinnata has been recognized for its potential in genetic improvement due to its highest resistance to CABMV and other phytopathogens. Metabolomic and histological alterations of P. c

2. A survey of RNA genome viruses in Lima bean crops of Northeastern Brazil
ABSTRACT Lima bean plants showing mosaic and leaf distortion symptoms, similar to those induced by viruses, were observed in several production areas in the states of Ceará and Piauí, Northeastern Brazil. The aim of this study was to identify RNA genome viruses that infect lima bean. Field research was conducted from 2017 to 2018. Fifty-five symptomatic sa

3. Effects of acetamiprid on Lipaphis pseudobrassicae (Hemiptera: Aphididae) resistant and susceptible to the parasitoid Diaeretiella rapae (Hymenoptera: Braconidae, Aphidiinae)
ABSTRACT This study evaluated the relationship between the resistance of Lipaphis pseudobrassicae to the parasitoid Diaeretialla rapae and the effects of the insecticide acetamiprid on the aphid. Four groups of L. pseudobrassicae collected in Uberlândia, MG, were used. The first two were formed by individuals of the same clone (C1), which were resistant (C1

4. Selection strategies in a segregating passion fruit population aided by classic and molecular techniques
ABSTRACT Combining the use of agronomic, disease-resistance, and molecular informationcan greatly contribute to genetic progress in breeding programs. This study was developed to estimate the genetic distance between genotypes derived from backcrosses and their parents using morphoagronomic and molecular information and information pertaining to resistance t

5. Backcrosses in a segregating population of Passiflora mediated by morphoagronomic and resistance traits
ABSTRACT The present study aims to characterize the genetic diversity of Passiflora setacea, P. edulis, their hybrids, and first-backcross progenies, and to indicate promising recombinants for generation advancement in a breeding program for transferring resistance to cowpea aphid-borne mosaic virus (CABMV). Ninety-one genotypes were evaluated for 37 morphoa

6. Potential of predatory Neotropical ladybirds and minute pirate bug on strawberry aphid
Abstract Laboratory trials were performed to determine the impact of three Neotropical predatory coccinellids (Cycloneda sanguinea, Eriopis connexa and Coleomegilla quadrifasciata) and a minute pirate bug (Orius insidiosus) on Chaetosiphon fragaefolii, an important strawberry aphid pest. The predation on C. fragaefolii nymphs and adults, as well as the time

7. Silicon as resistance inducer in to control black aphid Aphis craccivora Koch, 1854 in Phaseolus lunatus lima beans
RESUMO São poucos os registros no Brasil de insetos associados à cultura da fava; entre eles, destaca-se o pulgão preto Aphis craccivora Koch, 1854. O objetivo deste estudo foi avaliar os efeitos da aplicação de silício na indução de resistência de plantas de feijão-fava Phaseolus lunatus a esse inseto. O experimento foi conduzido no Laboratório d

9. Preferences and demographic parameters of cowpea aphid on advanced lines of semiprostrate cowpea
Resumo: O objetivo deste trabalho foi determinar a preferência e os parâmetros demográficos do pulgão-preto (Aphis craccivora), em linhagens avançadas de feijão-caupi (Vigna unguiculata) de porte semiprostrado, e verificar a existência e o tipo de resistência da planta ao ataque do inseto. Avaliou-se a preferência do inseto a 20 genótipos de feijã

10. Thermal requirements and age-specific life tables of cowpea aphids in cowpea under natural field conditions
RESUMO: As exigências térmicas dos insetos, bem como as tabelas de vida, são ferramentas importantes para o manejo ecológico de pragas. Assim, objetivou-se elaborar as tabelas de expectativa de vida específicas para Aphis craccivora em diferentes épocas do ano e, como base em suas exigências térmicas, prever a ocorrência de adultos em condições de

11. Glandular trichomes that mediate resistance to green peach aphid in tomato genotypes from the cross between S. galapagense and S. lycopersicum
ABSTRACT. The aim of this study was to verify the resistance of tomato genotypes (crossed with Solanum galapagense) to the green peach aphid, Myzus persicae, and the association of this resistance with glandular trichomes. Leaf trichomes were quantified for seven F2 genotypes of the BPX-486 population derived from crossing S. lycopersicum ‘TOM-684’ and S
