“…Chrysodeixis includens is found all across the Americas and prefers soybean as host plants (Lafontaine and Poole 1991, Kidd and Orr 2001, Baldin et al 2014, Barrionuevo and San Blás 2015, Formentini et al 2015, Palma et al 2015, Specht et al 2015). Rachiplusia nu is restricted to southern South America (Barbut 2008) and is reported to feed on alfalfa ( Medicago sativa L.), flaxseed ( Linum usitatissimum L.), sunflower ( Helianthus annuus L.), tobacco ( Nicotiana tabacum L.), and soybean (Ruffinelli 1942, Pastrana 2004, Specht et al 2006, Barrionuevo et al 2012, Luz et al 2014, Rimoldi et al 2015). Trichoplusia ni is cosmopolitan (Eichlin and Cunningham 1978, Lafontaine and Poole 1991) and prefers cabbages ( Brassica oleracea var.…”

Loopers such as Chrysodeixis includens (Walker), Rachiplusia nu (Guenée), and Trichoplusia ni (Hübner) are important defoliators in soybean, sunflower, and crucifer crops, respectively, in countries of the Americas. The biotic potential of these polyphagous species of Plusiinae was comparatively examined considering crop rotation and succession scenarios in which crucifer crops are cultivated during or after Brazilian winter. All the species developed and reproduced on soybean (BRS 133 Embrapa) and forage turnip (Cati AL 1000, Wolf Seeds do Brasil). The development of C. includens was similar on both host plants. The survival of R. nu was lower on forage turnip than on soybean. In contrast, T. ni performance (survival, fecundity, pupal weight) was better on forage turnip than on soybean. This suggests that in crop rotation and succession scenarios of soybean after brassicacea, C. includens is likely to have a higher number of generations per year and could be potentially more harmful.

“…Many problems are caused by the large area devoted to growing tobacco, as well as the great demand on use of synthetic products for their maintenance, causing environmental impacts and damages the health of farmers and the population in general (Specht, 2006). Considering this, more substantial researches, as well as effective actions that are able to reduce the environmental impacts of tobacco crop without a production affect, assume great importance and urgency.…”

Occurrence of social wasps (Hymenoptera: Vespidae) in farming of organic tobacco (Nicotiana tabacum L.) in south of Brazil

2020

This work aims to recognize and record the occurrence of species of social wasps (Polistinae) in organic tobacco crops, as well as to point out possible species that may be used in future biological control programs. The research was conducted in Virginia-type tobacco farming with organic management in two regions in south of Brazil. The collections were carried out with Malaise trap, during the harvests 2008/2009, 2009/2010 and 2010/2011. A total of 2.738 wasps, from which 23 species distributed in six genera was collected. Polistes was the most diverse genus (8 species), followed by Polybia, Mischocyttarus, Agelaia, Bachygastra and Protonectarina. Polybia scutellaris was the most abundant species, being considered eudominant. Agelaia multipicta and Polybia sericea with are also among the most abundant. This information is relevant for the insertion of social wasps with potential agents in the biological control of tobacco pests.

“…The Southern Region of Brazil is responsible for the greatest amount of cropped area of this country, with approximated 155,100 hectares in 2013-2014 seasons, with a final production of 247,410 ton [8] [9]. This is a very important crop in economic terms, as it presents a very prof- from the cropping to the manufacturing of the final products [10].…”

Populational Fluctuation and Distribution of <i>Epitrix</i> spp. Foudras (Coleoptera: Chrysomelidae) in the Organic Tobacco Management in Santa Cruz do Sul, RS, Brazil

Among the chrysomelids, some species are considered agricultural pests, such as some representatives of Epitrix spp. Popularly known as tobacco flea, these beetles cause damage to tobacco (Nicotiana tabacum L.) by feeding on the leaf surface, causing injuries, reducing productivity and the final quality of the product to be marketed. However, studies of the biology and interactions of these individuals with the environment become essential in order to develop effective and sustainable control measures. The objective of this study was to analyze the distribution and population fluctuation of Epitrix spp., as well as to evaluate the possible influence of temperature, rainfall and adjacent vegetation on the population dynamics of this beetle in organic tobacco growing in the municipality of Santa Cruz of the South, RS. The collections were carried out weekly during the 2011/2012 harvest, using Malaise and Pit-fall traps, distributed in four points along three lines. A total of 1584 individuals belonging to the genus Epitrix were collected, and their greatest abundance was observed in late January and early February 2012 due to climatic factors, such as rainfall and temperature, favorable to the development of specimens and the tobacco leaf harvesting reduced the availability of food and conditioned a greater movement of these individuals in the crop. The results presented here are of great importance for deciding the best methodology for controlling the smoke flea, as well as knowing the influence of abiotic factors on the behavior of these organisms in the field.
