Temperate fruit crops are an important economic activity for growers in southern Brazil. However, several pest species are associated to apple (Malus domestica Borkh.) crops in Brazil. Pesticides are largely used to control them and one way to change this is to combine selective pesticides and predator insects. The goal of this research was to evaluate the effects of the abamectin, carbaryl, fenitrothion, methidathion, sulfur, and trichlorfon pesticides on the survival and stage length of larvae and pupae, adult oviposition from treated larvae, and hatched eggs of two Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) populations. The compounds were sprayed on glass plates in accordance with the International Organization for Biological Control (IOBC) recommendations. First-and second-instar larvae were exposed to pesticide residues. Carbaryl, fenitrothion, and methidathion caused 100% mortality of first-and second-instar larvae. Changes in the number of eggs laid by females from first-and second-instar larvae exposed to residues of abamectin and sulfur, or abamectin, sulfur, and trichlorfon, respectively, were not observed. Only abamectin reduced the number of hatched eggs laid by females in Bento Gonçalves from treated first-instar larvae. Sulfur reduced the viability of C. externa eggs in Bento Gonçalves and Vacaria females from treated second-instar larvae, whereas trichlorfon and abamectin reduced the viability of eggs in Vacaria females. In conclusion, carbaryl, fenitrothion and methidathion were harmful to C. externa. Trichlorfon was harmful to first-instar larvae and slightly harmful to second-instar larvae. Abamectin and sulfur were slightly harmful to first-instar larvae and harmless to second-instar larvae.

“…Significant losses > 12% were estimated even after taking control measures (Oerke 2006). Current control measures include the use of different chemicals as pesticides which is associated with high cost, pesticide resistance and environmental risks (Costa et al 2003). Alternative methods should be opted for the control of these sucking insects.…”

Evaluation of cotton germplasm for morphological and biochemical host plant resistance traits against sucking insect pests complex

et al. 2021

Background Sucking insect pests cause severe damage to cotton crop production. The development of insect resistant cotton cultivars is one of the most effective measures in curtailing the yield losses. Considering the role of morphological and biochemical host plant resistance (HPR) traits in plant defense, 12 cotton genotypes/varieties were evaluated for leaf area, leaf glanding, total soluble sugars, total soluble proteins, total phenolics, tannin and total flavonoids against fluctuating populations of whitefly, thrips and jassid under field conditions. Results The population of these insects fluctuated during the growing season and remained above threshold level (whitefly > 5, thrips > (8–10), or jassid > 1 per leaf) during late June and early July. Strong and negative association of whitefly (r = − 0.825) and jassid (r = − 0.929) with seed cotton yield was observed. Mean population of insects were the highest in Glandless-1 followed by NIA-82 and NIA-M30. NIAB-Kiran followed by NIAB-878 and Sadori were the most resistant, with the mean population of 1.41, 1.60, 1.66 (whitefly); 2.24, 2.32, 2.53 (thrips) and 0.37, 0.31, 0.36 (jassid), respectively. The resistant variety NIAB-Kiran showed less soluble sugars (8.54 mg·g− 1), soluble proteins (27.11 mg·g− 1) and more phenolic (36.56 mg·g− 1) and flavonoids (13.10 mg·g− 1) as compared with the susceptible check Glandless-1. Moreover, all insect populations were positively correlated with total soluble sugars and proteins. Whitefly populations exhibited negative response to leaf gossypol glands, total phenolics, tannins and flavonoids. The thrips and jassid populations had a significant and negative correlation with these four biochemical HPR traits. Conclusion The identified resistant resources and HPR traits can be deployed against sucking insect pests’ complex in future breeding programs of developing insect resistant cotton varieties.

“…É importante utilizar estratégias de conservação e aumento de predadores na cultura da macieira com destaque para os crisopídeos, que têm apresentado tolerância aos produtos fitossanitários utilizados nos diferentes agroecossistemas (CARVALHO et al, 2002;COSTA et al, 2003). Essa estratégia busca encontrar produtos seletivos que, de forma eficiente, controlem as pragas causando o menor impacto possível sobre as populações de inimigos naturais (CARVALHO, 2002).…”

Neste trabalho, foi avaliado o efeito de inseticidas sobre ovos de duas populações de Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae). O trabalho foi realizado em laboratório (25±2°C, UR de 70±10% e fotofase de 12 horas) avaliando-se inseticidas, nas concentrações indicadas pelos fabricantes e/ou que estão em fase de pesquisa para o controle da mariposa-oriental, lagarta-enroladeira e mosca-das-frutas na cultura da macieira. Os produtos e dosagens (g ou mL do p.c. 100L-1 de água) avaliados foram: fosmet (Imidan 500 PM - 200), metoxifenozide (Intrepid 240 SC - 60), tebufenozide (Mimic 240 SC - 60), benzoato de emamectina (Proclaim 5 SG - 15), spinosad (Tracer 480 SC - 20), etofenprox (Trebon 100 SC - 150), clorpirifós etil (Lorsban 480 BR - 150) e testemunha (somente água). As pulverizações foram realizadas em ovos com até 12 horas de idade, utilizando-se torre de Potter. Avaliaram-se a viabilidade dos ovos, o período embrionário, e a sobrevivência das larvas de primeiro e segundo estádios provenientes dos ovos tratados. A toxicidade dos produtos foi determinada em função da mortalidade acumulada do predador durante o seu desenvolvimento, classificando-os conforme escala proposta pela IOBC. As duas populações de C. externa apresentaram o mesmo padrão de resposta aos produtos fitossanitários avaliados quando aplicados sobre ovos. Fosmet, metoxifenozide, tebufenozide, benzoato de emamectina, spinosad e etofenprox foram considerados inócuos, e clorpirifós etil levemente nocivo a ovos de C. externa, provocando a redução de 43,7% na viabilidade dos ovos e afetando em 20% a sobrevivência das larvas de primeiro estádio originadas dos ovos tratados.
