1. Symptomatology associated with “Purple top”, an emerging disease of solanaceous fruit species
ABSTRACT “Purple top” is an emerging disease that affects solanaceous crops, reported mainly on Solanum tuberosum (potato). Additionally, Bactericera cockerelli has been reported as the insect vector of Candidatus Liberibacter solanacearum (CaLso), a pathogen that has been associated with this disease. However, the information about this disease in Andea

2. Identification of Two Additional Behaviorally Active Gland Constituents of Female Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae)
The sugarcane borer, Diatraea saccharalis (Fabricius), is the major pest insect attacking sugarcane crops in Brazil. Population control by insecticide treatment is not efficient due to simultaneous presence of all developmental stages of the insect throughout the year, and alternative control methods are needed. Two female-produced sex pheromone components,

3. Effectiveness of coffee leaf miner control associated with spray deposition in coffee leaves
ABSTRACT Coffee production faces challenges due to the susceptibility of the crop to insects. Owing to the coffee leaf miner Leucoptera coffeella, which is one of the main insect pests, the technology for the application of phytosanitary measures becomes the main challenge for coffee growers. This study aimed to evaluate the effectiveness of coffee leaf mine

4. Insecticidal activity of essential oils in controlling fall armyworm, Spodoptera frugiperda
RESUMO: A lagarta-do-cartucho, Spodoptera frugiperda (Lepdoptera: Noctuidae), é uma das principais pragas na cultura do milho e nos últimos anos vem desenvolvendo resistência a produtos químicos e à tecnologia Bt. Métodos alternativos de controle, como o emprego de óleos essenciais, são um passo importante na implementação de estratégias de manejo

5. Control potential of Heterorhabditis amazonensis (Rhabditida: Heterorhabditidae) in avocado borer, Stenoma catenifer (Lepidoptera: Elachistidae)
ABSTRACT Stenoma catenifer is considered the main pest of avocado, making impossible to commercialize the infested fruits. This study was conducted with the objective of evaluating the potential of Heterorhabditis amazonensis MC01 in the field control of avocado borer, as well as the nematode release method. Two treatments were tested, namely: release of dea

6. Advances in induced resistance by natural compounds: towards new options for woody crop protection
ABSTRACT: The activation of defensive responses of plants is a promising tool for controlling pests in conventional agriculture. Over the last few years, several compounds have been studied to protect crops from pests, without displaying direct toxicity for pathogenic organisms. These compounds have the ability to induce a priming state on the plants that re

7. The unfulfilled promises of scorpion insectotoxins
Abstract Since the description and biochemical characterization of the first insect-specific neurotoxins from scorpion venoms, almost all contributions have highlighted their potential application as leads for the development of potent bioinsecticides. Their practical use, however, has been hindered by different factors, some of which are in

8. Preliminary screening of the larvicidal effect of Brevibacillus laterosporus strains against the blowfly Chrysomya megacephala(Fabricius, 1794) (Diptera: Calliphoridae)
AbstractINTRODUCTION: This study evaluated whether different strains of Brevibacillus laterosporus could be used to control larvae of the blowfly Chrysomya megacephala , a pest that affects both human and animal health.METHODS:Mortality rates were recorded after 1-mL suspensions of sporulated cells of 14 different strains of B. laterosporus were added to 2.5

9. Biological Control in Brazil: an overview
The use of Biological Control methods is on the increase, mainly as a result of the mobilization of human resources in entomology studies since the establishment of graduate programs in this country in the 1960s. This review approaches the retrospective of Biological Control in Brazil in recent decades, with an emphasis on the "culture of applying agrochemic

10. Insects associated with tropical foliage produced in the coffee growing region of Colombia
We conducted a survey of insects and pest management practices on 34 farms growing ornamental tropical foliage plants in the central coffee region of Colombia over two years. Tropical foliage provided habitat for a diverse range of insects. In total, phytophagous or detritivorous insects from six orders, 40 families and 62 genera were collected. The most com

11. A procura de bactérias degradadoras de metamidofós. / Searching for methamidofos degrading bacteria.
Methamidophos is a strong acetylcholinesterase inhibitor and, therefore, a very toxic organophosphorus insecticide. This product has been widely employed for pest control in a variety of cultures, but little information is available about its biodegradation. 12 bacteria were isolated and characterized, from water and soil samples obtained from a site contami

12. Development of the mosaic of dominant arboreal ants and its importance to the biological control of insects associated with cocoa (Theobroma cacao L.) / Desenvolvimento do mosaico de formigas arborícolas dominantes e sua importância no controle biológico natural dos insetos associados ao cacaueiro (Theobroma cacao L.)
Agroforests contribute to the survival of many native species. The cocoa plantations inserted in the Atlantic Forest biome in Southeast Bahia contribute to the conservation of a large amount of organisms, including ants. The evaluation of the ontogenetic succession of ants can help understanding the mosaic dynamics of the arboreal ants. Since this mosaic can
