A new species of Palpita Hübner (Crambidae, Spilomelinae), Palpita maritima, sp. n., is described from maritime forests of the coastal plains of southeastern United States.

A new species of Lixophaga Townsend (Diptera: Tachinidae) from Colombia, Lixophaga puscolulo Carrejo & Woodley, sp. nov., is described and illustrated. It is a parasitoid of the tomato fruit borer, Neoleucinodes elegantalis (Guenée) (Lepidoptera: Crambidae), an insect pest of Solanum quitoense Lam., in Colombia. Aspects of its biology are briefly discussed.

A checklist of the 31 Chinese species of Udea is given, including the new species and new records. Udea curvata sp. n. and Udea albostriata sp. n. are described and illustrated. Udea exigualis (Wileman, 1911), Udea stationalis Yamanaka, 1988, Udea prunalis (Denis & Schiffermüller, 1775), Udea elutalis (Denis & Schiffermüller, 1775) and Udea cyanalis (La Harpe, 1855) are newly recorded for China.

Herpetogramma sphingealissp. n., a new species of Crambidae (Lepidoptera), is described from Québec, Canada. The species is included in the genus Herpetogramma Led., 1863, a genus in the subfamily Spilomelinae. Adults and genitalia of this species are described and illustrated, as well as those of Herpetogramma aeglealis (Walker, 1859) and Herpetogramma thestealis (Walker, 1859), and adults of ...

Southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera: Crambidae), is a major insect pest of corn, Zea mays L., in the southern United States. Germplasm lines with resistance to southwestern corn borer have been developed and released by the USDA-ARS. Two single-cross hybrids produced by crossing germplasm lines with resistance to southwestern corn borer and a susceptible single-cros...

Dipel-resistant and -susceptible strains of Ostrinia nubilalis (Hübner) were evaluated for larval mortality and growth inhibition when fed diets containing individual Bacillus thuringiensis protoxins. Resistance ratios for four of the protoxins in Dipel (Cry1Aa, Cry1Ab, Cry1Ac, and Cry2Aa) were 170-, 205-, 524-, and > 640-fold, respectively, considerably higher than the 47-fold resistance to Di...

Transgenic corn expressing the insecticidal toxin from Bacillus thuringiensis Berliner is gaining support as an effective control technology for use against lepidopteran pests, particularly European corn borer, Ostrinia nubilalis Hübner (Lepidoptera: Crambidae). However, there is concern that widespread adoption of transgenic plants will rapidly lead to B. thuringiensis toxin resistance. Thus, ...

Surveys were completed in Eritrea, Ethiopia, Kenya, Madagascar, Mozambique, Tanzania, Uganda and Zanzibar to assess the lepidopteran stem borer species diversity on wild host plants. A total of 24,674 larvae belonging to 135 species were collected from 75 species of wild host plants belonging to the Poaceae, Cyperaceae and Typhaceae. Amongst them were 44 noctuid species belonging to at least ni...
