“…This would be achieved by preventing larvae from reaching the adult stage in tobacco treated with spinosad. Whereas single‐larva assays were available,17 specific multiple‐organism emergence assays were developed successfully for both insects. Previous versions of such assays had already been described in the literature, but with the adult insects laid directly onto the substrate (progeny production/reduction tests) 12, 20.…”

“…Diet incorporation assays were used to evaluate the insecticidal activity of spinosad on L serricorne larvae during the first 2 weeks after hatching. Single‐organism bioassays were conducted as described previously 17. Briefly, newly hatched larvae were placed individually into microtitre plate wells filled with ground tobacco sprayed with spinosad as described above.…”

Every year raw tobacco and manufactured tobacco products are lost to two major storage pests, the cigarette beetle, Lasioderma serricorne (F) and the tobacco moth, Ephestia elutella (Hiibner). Post-harvest management of both insects is achieved through sanitation, insect monitoring and fumigation with phosphine. However, insect resistance to phosphine and control failures have been reported, and fumigants are under constant regulatory pressure. Here we report the evaluation of spinosad, a bioinsecticide derived from the fermentation of the soil micro-organism Saccharopolyspora spinosa Mertz & Yao. Spinosad was first registered in 1997 and is now widely used as a field pest control agent on many crops, including tobacco. The insecticidal activity of the fermentation product (technical spinosad, TS) was measured by diet incorporation assays against L serricorne and E elutella larvae. Mortality levels were determined on newly hatched larvae and over the whole insect life cycle. For both species, no emergence of adult insects was observed in cured tobacco sprayed with 50mg TS kg(-1) and inoculated with eggs or newly hatched larvae. These results indicated that spinosad has potential for the control of both species in stored tobacco, since 100% control of both pests could be achieved at 50 mg TS kg(-1), and with almost full control (90-95%) at 10 mg kg(-1). We also monitored the stability of the product on cured tobacco. The original concentration of the main active component of TS, spinosyn A, did not change significantly over 18 months, indicating no loss of spinosad during a typical leaf storage period of time. Bioassays against larvae confirmed that the bioinsecticidal activity of spinosad was retained.

Potencial de desenvolvimento de Lasioderma serricorne (Fabricius, 1792)(Coleoptera: Anobiidae) em dietas contendo soja Potential for the development of Lasioderma serricorne (Fabricius, 1972) (Coleoptera: Anobiidae) in diets with soybean ResumoLasioderma serricorne é uma praga cosmopolita, com grande potencial de adaptação a uma variedade de produtos alimentares de origem vegetal. Está sendo encontrada em soja armazenada, causando preocupação aos armazenadores. Este trabalho buscou determinar o potencial de adaptação de L. serricorne em produtos à base de soja, estudando o desenvolvimento deste inseto em diferentes dietas contendo soja e avaliando o número e a intensidade de adultos emergidos, e a duração do período de ovo até adulto. Os insetos foram submetidos às seguintes dietas: 1) grão de soja inteiro + grão de soja quebrado (proporção de 3:2); 2) farinha de soja + levedo de cerveja (proporção de 5:1); 3) farinha de soja + gérmen de trigo + levedo de cerveja (proporção de 5:2:1); e 4) fubá + gérmen de trigo + levedo de cerveja (proporção 5:2:1). Para avaliar a sobrevivência de adultos, foi acrescentado um tratamento controle, sem alimento. Ficou evidenciado que a espécie L. serricorne é um inseto que se desenvolve e completa o ciclo biológico em dietas contendo soja, podendo se tornar uma praga com importância econômica em alimentos. A dieta que apresentou o melhor desempenho na produção de adultos de L. serricorne foi a que continha farinha de soja + gérmen de trigo + levedo de cerveja, com um pico de emergência dos adultos aos 49 dias após a postura, iniciando-se aos 42 dias e se prolongando até os 73 dias após a postura. Adultos de L. serricorne sobreviveram por até 38 dias na ausência de alimento, porém somente de 20 a 22 dias em dietas à base de grãos e farinha de soja, gérmen de trigo, levedo de cerveja e fubá.

Essential oils can have an impact on behavioural responses of cigarette beetle (Lasioderma serricorne). In this study, we provide evidence that some chemical compounds in essential oil of tobacco (Nicotiana tabacum) leaves, which were subjected to hydrodistillation and extracted with n-hexane, can strongly attract L. serricorne significantly. Two main chemical constituents, 6, 8-nonadien-2-one, 8-ethyl-5 -(1-methylethyl) and 1-(2, 6, 6-trimethyl-1, 3-cyclohexadien-1-yl) 2 -buten-1-one, in the essential oils were confirmed by GC-MS analysis. This result could be helpful to find some chemical compositions from N. tabacum as leading compounds for development of new bionic attractant.
