Nonpreference for Oviposition of Sugarcane Borer (Lepidoptera: Crambidae) in Sugarcane Seedlings Is Influenced by Ripening Group and Plant Age.

The sugarcane borer Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) is considered the main sugarcane pest in many countries. The use of plant genotypes less preferred by insects are among the alternative methods to control this species which can be used alone or associated with other control methods such as biological control in Integrated Pest Management (IPM) programs. We assessed if the nonpreference for oviposition of D.

Importance of Sugar for the Development of Diatraea saccharalis (Lepidoptera: Crambidae) on Artificial Diet.

To obtain insects with biological characteristics similar to those of wild insects, this study evaluated the development of Diatraea saccharalis (Fabricius) reared on artificial diet containing different sugar concentrations. First-instar caterpillars were fed seven artificial diets containing 0, 6.56, 13.

Effect of temperature on immatures of Stiretrus decastigmus (Hemiptera: Pentatomidae).

Stiretrus decastigmus (Herrich-Schaeffer) (Hemiptera: Pentatomidae) is an important predator of the insect pest Microtheca ochroloma Stal (Coleoptera: Chrysomelidae). The present study investigated the pre-imaginal development of S. decastigmus at different temperatures.

Toxomerus duplicatus Wiedemann, 1830 (Diptera: Syrphidae) preying on Microtheca spp. (Coleoptera: Chrysomelidae) larvae.

Microtheca spp. (Coleoptera: Chrysomelidae) are insect pests primarily related to Brassicaceae crops. In the State of Rio Grande do Sul (RS), southern Brazil, they are found on forage turnip, Raphanus sativus L.
