Side-Effects of Glyphosate to the Parasitoid Telenomus remus Nixon (Hymenoptera: Platygastridae)

et al. 2016

The aim of this study was to compare the side-effects of glyphosate to the parasitoid Telenomus remus Nixon (Hymenoptera: Platygastridae) when parasitoids were exposed to this chemical at the pupal (inside host eggs) and adult stages. Bioassays were conducted under laboratory conditions according to the International Organization for Biological Control (IOBC) standard methods for testing side-effects of pesticides to egg parasitoids. Different glyphosate-based pesticides (Roundup Original®, Roundup Ready®, Roundup Transorb®, Roundup WG®, and Zapp Qi®) were tested at the same acid equivalent concentration. Treatments were classified following the IOBC toxicity categories as (1) harmless, (2) slightly harmful, (3) moderately harmful, and (4) harmful. When tested against T. remus adults, Roundup Original®, Roundup Ready®, Roundup Transorb®, and Roundup WG® reduced parasitism 2 days after parasitoid emergence, being classified as slightly harmful. Differently, when tested against T. remus pupae, all tested glyphosate-based products did not differ in their lethal effect and therefore did not reduce T. remus adult emergence or parasitism capacity, being classified as harmless. However, differences on sublethal toxicity were found. Parasitism of individuals emerging from parasitized eggs sprayed at the pupal stage of T. remus with Zapp Qi® was lower compared to control, but parasitism was still higher than 66%, and therefore, Zapp Qi® was still classified as harmless. In conclusion, all tested glyphosate-based products can be used in agriculture without negative impact to T. remus as none was classified as harmful or moderately harmful to this parasitoid when exposure occurred at the pupal or adult stages.

Desenvolvimento de Spodoptera eridania (Cramer) (Lepidoptera: Noctuidae) em diferentes hospedeiros

et al. 2013

Spodoptera eridania (Cramer) is a growing pest in crops that has been causing damage due to defoliation and lesion in reproductive structures, which requires studies of development in different types of hosts. The objective of this study was to evaluate the development of S. eridania in different species of host plants. The larvae were reared in laboratory in cotton plants of the Delta Opal cultivar. The caterpillars of newly hatched larvae were placed in Petri dishes and fed on these plants: black velvet bean (Stizolobium aterrimum), guandu bean (Cajanus cajan), jack bean (Canavalia ensiformes), forage radish (Raphanus sativus), sunnhep (Crotalaria juncea) and millet (Pennisetum americanum). The following parameters were evaluated: attractiveness and consumption in a multiple choice test; viability; larval and pupal period and weight; sex ratio; adult longevity; and total duration of the development cycle. The jack bean and forage radish plants showed greater attractiveness and were the most consumed ones by S. eridania caterpillars. The larval period was shorter among the larvae fed on black velvet beans in comparison to guandu beans, jack beans, forage radish and C. juncea. Larvae fed on forage radish and C. juncea leaves had the heaviest pupal weight. The best progress of caterpillars was obtained in the following hosts: guandu bean, forage radish and C. juncea. The millet had a negative influence on the biological parameters of caterpillars, thus not proving to be a viable host, since larval mortality was of 100%.KEYWORDS: black caterpillar; nutritional ecology; alternative host. RESUMO:Spodoptera eridania (Cramer) é uma praga em expansão nas culturas, que vem causando prejuízos pela desfolha e pela lesão nas estruturas reprodutivas, o que leva à necessidade de estudos de desenvolvimento em diferentes tipos de hospedeiros. O objetivo do trabalho foi estudar o desenvolvimento de S. eridania em diferentes espécies de plantas hospedeiras. As lagartas foram criadas em laboratório em plantas de algodoeiro do cultivar Delta Opal. As lagartas recém-eclodidas foram individualizadas em placas de Petri e alimentadas com as plantas: mucuna-preta (Stizolobium aterrimum), feijão--guandu (Cajanus cajan), feijão-de-porco (Canavalia ensiformes), nabo-forrageiro (Raphanus sativus), Crotalaria juncea e milheto (Pennisetum americanum). Os parâmetros avaliados foram: atratividade e consumo em teste com chance de escolha; viabilidade; período e peso larval e pupal; razão sexual; longevidade de adultos; e duração total do ciclo de desenvolvimento. As plantas de feijão-de-porco e nabo--forrageiro apresentaram maior atratividade e foram as mais consumidas pelas lagartas de S. eridania. O período larval foi menor nas lagartas alimentadas com mucuna-preta do que com feijão-guandu, feijão-de-porco, nabo-forrageiro e C. juncea. Lagartas alimentadas com folhas de nabo-forrageiro e C. juncea tiveram os maiores peso de pupa. Os melhores desenvolvimentos das lagartas foram obtidos nos hospedeiros feijão-guandu, nabo-forrageiro e...

“…Entretanto, nos últimos anos, a espécie tem sido relatada como praga importante nas culturas do algodão e soja (SANTOS et al, 2005;SANTOS et al, 2010), tomate (MIRANDA et al, 2005) e frutífe ras de clima temperado, com destaque para a macieira (NORA et al, 1989;FONSECA, 2006). No Estado do Rio Grande do Sul, S. eridania tem sido encontrada causando prejuízos importantes também em morangueiro e videira, resultando na necessidade de aplicação de inseticidas durante a safra.…”

BIOLOGY, FERTILITY LIFE TABLE AND EFFECT OF INSECTICIDES ON Spodoptera eridania (CRAMER) (LEPIDOPTERA: NOCTUIDAE) IN STRAWBERRY AND GRAPEABSTRACT-The biology of Spodoptera eridania was studied in the laboratory (22±1ºC, RH 70±10%, 14 hours of photoperiod) in leaves of strawberry (Fragaria x ananassa cv. 'Aromas') and grape (Vitis vinifera cv. 'Cabernet Sauvignon'). The duration and viability of the entire cycle were respectively 52.2±1.32 days and 37.6% for strawberry and 42.2±0.45 days and 25.5% for grapes. The sex ratio in strawberry was 0.58 and 0.48 on grape. The average longevity of males and females in strawberry was 16.3±1.16 and 15.8±1.85 days, respectively, and 5.6±0.88 and 7.3±0.83 days in grape. The mean fecundity was 1,747.5±187.32 eggs per female in strawberry and 1,764.9±289.04 on grape. The life table of fertility showed that the net reproduction rate and finite rate of increase were 394.89 and 1.10, respectively, for strawberry and 213.98 and 1.12 for grapevine. Strawberry cv. 'Aromas' and grape cv. 'Cabernet Sauvignon' are suitable hosts providing similar population growth rates of S. eridania.
