Spilomelinae compreende mais de 5.200 espécies descritas em todo o mundo. Várias são conhecidas por seu impacto econômico nas lavouras, ocorrendo altas populações plantas hospedeiras, com diferentes graus especificidade ao hospedeiro. O objetivo foi registrar lagartas Syngamia florella (Stoll in Cramer & Stoll) (Lepidoptera: Crambidae: Spilomelinae) alimentando-se folhas Ipomea batatas (L.) Lam...

Tetracona amathealis (Walker, 1859) (Lepidoptera: Crambidae) is previously known from Australia and New Guinea, where it feeds on the native Eucalyptus tereticornis Sm. (Myrtaceae). The objective of this study was report, for first time, T. in Indonesia as well to record new host plants insect. Were collected manually a grandis W. Hill. × pellita F. Muell. hybrid commercial plantation Riau, Sum...

The European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is a quarantine pest for several fresh commodities, including corn-on-the-cob, bell peppers, and green beans. Methyl bromide fumigation is the usual phytosanitary treatment, but the fumigant is under increasing regulation as a stratospheric ozone-depleting substance. Ionizing radiation is a relatively new commercial ...

2019. augusztus-szeptember fordulóján Budapest XXI. kerületében Csepelen lámpázással a Duponchelia fovealis ZELLER, 1847 (Crambidae) két hím egyedét észleltem, majd újabb példány érkezett 2020 szeptemberében. júniusában belvárosában Cacoecimorpha pronubana (HÜBNER, 1799) (Tortricidae) imágóinak tömegrajzását figyeltem meg. Később, augusztusban, ugyanott ismét észleltem C. néhány egyedét. Úgy tű...

The European corn borer, Ostrinia nubilalis Hübner (Lepidoptera: Crambidae) has been a major pest of corn and other crops in North America since its accidental introduction nearly a hundred years ago. Wide adoption of transgenic corn hybrids that express toxins from Bacillus thuringiensis, referred to as Bt corn, has suppressed corn borer populations and reduced the pest status of this insect i...

Choice tests were conducted to determine feeding preferences of European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), neonates for 15 species of plants. Percentage of neonates accepting (found on) each leaf disc after 24 h was measured using choice tests. Initially, nine species of plants were evaluated. The following year, 10 plant species were evaluated during O. nubilali...

Using the phenylpyrazole insecticide, fipronil for selection in the laboratory, a resistant Wenzhou strain of the rice stem borer, Chilo suppressalis (Walker) (Lepidoptera: Crambidae) had an LD(50) at least 45.3 times greater than the susceptible Anhui strain. The realized resistant heritability (h(2)) of 0.213 showed that the tolerant phenotype was moderately heritable and had potential to dev...
