Abstract Production and sale of botanical insecticides depend on knowing the potential opportunities for these products. Essential oils from plants secondary metabolism can control pests, especially in agricultural systems where synthetic insecticides are limited, as in organic agriculture. The objective of this study was to evaluate the toxicity of essential oils to Diaphania hyalinata (Lepidoptera: Crambidae) and to show regions with the potential to use Cinnamomum zeylanicum, Citrus sinensis, and Syzygium aromaticum in the formulation and commercialization of insecticides to control this insect. The C. zeylanicum oil was more toxic to larvae and pupae and the S. aromaticum to eggs of D. hyalinata. Essential oils are an alternative for the management of D. hyalinata. The production of pesticides from essential oils of C. zeylanicum, C. sinensis, and S. aromaticum to control D. hyalinata has high potential in America. Also, Asia, Africa, Europe, the Middle East, and Asia can extract these plants to formulate insecticide molecules for the America countries. products pests limited agriculture Lepidoptera (Lepidoptera Crambidae sinensis insect C S D Also Africa Europe East countries

Platyscytus decempunctatus Carvalho é um mirídeo de pequeno porte que vive durante seu ciclo de vida em plantas de Solanum cernuum Vell. (Solanaceae). A morfologia interna de P. decempunctatus foi estudada revelando que fêmeas possuem ovário do tipo telotrófico com três ovaríolos no ovário direito e cinco no esquerdo. Nas estruturas reprodutivas dos machos existe uma glândula acessória tubular bem desenvolvida. A fitofagia de P. decempunctatus foi confirmada devido a observações de pigmentos de clorofila no intestino de todos os espécimes dissecados. As glândulas salivares em formato tubular e os túbulos de Malpighi também foram discutidos.

Platyscytus decempunctatus Carvalho is a small mirid living throughout its life cicle plant Solanum cernuum Vell. (Solanaceae). The internal morphology of P. decempunctatus was studied and found that the female has a telotrophic ovary with three ovarioles in the right ovary and five in the left one. In the male reproductive trait there is a well developed tubular accessory gland. The phytophagous feeding habitat of P. decempunctatus was confirmed by the observations of chlorophyll pigments in the gut of all dissected specimens. The tubular salivary glands and the Malpighian tubules were also discussed.
