13. Performance and selection of tomato cultivars for organic cultivation in greenhouse
ABSTRACT Production of tomato fruits in organic systems has difficulties such as the use of adequate cultivars. The hypothesis is that organic cultivation has strength dependency of the selection of appropriate genotypes to increase the economic viability of fruit production. The present work aimed to test and obtain, under organic greenhouse system, cultiva

15. Genetic diversity, population structure and AFLP markers associated with maize reaction to southern rust
ABSTRACT Maize is one of the species with greater genetic diversity among cereals and possibly the most diverse crop species known. Accessing this variability is essential for maize breeding, allowing breeders to achieve progress of yield increasing, overcome environmental challenges or deal with pests and diseases. Among the maize diseases, southern rust is

16. Advances in Coconut palm propagation
Resumo O coqueiro (Cocos nucifera L.) é uma das mais importantes espécies tropicais utilizadas pelo homem, conhecida como “árvore da vida”. Nas últimas décadas, com a expansão das áreas de cultivo, limitações como a ocorrência de pragas, uniformidade de culturas, adaptação a diferentes ecossistemas e outras têm afetado a produção e a long

17. Perception of the Quality of Life of Tobacco Growers Exposed to Pesticides: Emphasis on Health, Hearing, and Working Conditions
Abstract Introduction Tobacco farming exposes workers to various health risks due to the high application of pesticides needed to control pests, weeds and fungal diseases that prevent the tobacco plant growth. Objective To analyze the perception of the quality of life of tobacco growers exposed to pesticides, with emphasis on general health, hearing, and

19. Popcorn germplasm resistance to fungal diseases caused by Exserohilum turcicum and Bipolaris maydis
ABSTRACT Compared with the common corn, popcorn shows greater susceptibility to pests and diseases occurrence, being the use of resistant cultivars the most efficient strategy. In this regard, Germplasm Banks deserve special attention because they contain accessions that can be used as sources of resistance in breeding programs. The State University of North

20. The search for novel insecticide targets in the post-genomics era, with a specific focus on G-protein coupled receptors
Insects are considered pests globally, implicated in the destruction of agricultural fields and transmission of pathogens that cause deadly human diseases, such as dengue, Zika and malaria. The diversity of the insecticide arsenal has remained stagnant for decades, but the recent rise of insecticide resistance fueled the discovery of novel modes of action, a

21. Cashew cultivation in Guinea-Bissau – risks and challenges of the success of a cash crop
In recent decades a boom in cashew (Anacardium occidentale)cultivation has taken place in Guinea-Bissau, leading to the replacement of traditional slash-and-burn agriculture by a cash crop. As a result, the country is currently one of the world’s largest producers of raw cashew nuts and the cashew sector has acquired enormous importance in Guinea-Bissau’

22. Successful crosses between fungal-resistant wild species of Arachis (section Arachis) and Arachis hypogaea
Peanut (Arachis hypogaea) is the fifth most produced oil crop worldwide. Besides lack of water, fungal diseases are the most limiting factors for the crop. Several species of Arachis are resistant to certain pests and diseases. This study aimed to successfully cross the A-genome with B-K-A genome wild species previously selected for fungal disease resistance

23. Lethal effects of a Mexican Beauveria bassiana (Balsamo) strain against Meccus pallidipennis (Stal)
The entomopathogenic fungus Beauveria bassiana (Balsamo 1835) Vuillemin is an effective alternative control agent against some agricultural pests and biological vectors of important diseases such as Chagas disease. In this work we studied an isolate of Beauveria bassiana from of the town of San Antonio Rayón, Puebla, Mexico and its entomopathogenic effects

24. Ocorrência de HLB e caracterização de Candidatus Liberibacter spp. no estado do Paraná
Huanglongbing (HLB) is considered the most important disease for citrus production around the world. Three bacteria species are associated with HLB, Ca. Liberibacter africanus, Ca. Liberibacter asiaticus and Ca. Liberibacter americanus. In Brazil, the disease was first reported in 2004, in the State of São Paulo. In Parana, HLB was reported for
