Simplified cytological procedures were developed for high resolution light microscopical study of sperm bundle structure in Heliothis virescens (F.). It was possible to separate parental, F1 hybrids ( H. subflexa (Guenee) females X H. virescens males

A complexity of abnormalities (duplication and deformation of elements) was found in eupyrene sperm cells in the progeny of Heliothis subflexa (Guenee) ♀ × H. virescens (F.) ♂ by using a rapid air-dry procedure for light microscopical study. The

Improved methods for obtaining good cytological preparations from testicular tissues of Lepidoptera are described. Testes were pretreated with various hypotonic solutions, fixed in Carnoy's, and slides prepared using air dry-squash and cell suspensio

The sexual behavior and chromosome complement of 4 species of Monodontomerus Westwood are described. Courtship involves approach, display (precopulatory behavior), and copulation. Male display consists of a repetitive series of sterotyped movements w

Haploid karyotypes composed of 5 metacentrics (T. umbilicatus, T. koebelei), 4 metacentrics plus 2 telocentrics (T. tubicola), 5 metacentrics plus 1 telocentric (T. warreni), 5 metacentrics plus 1 acrocentric (T. baccharidis, T. vesiculi, T. occident

A simple ammoniacal silver staining procedure, designated Ag-AS, differentially stains the chromosomal locations of ribosomal DNA in certain mammalian species. This was critically demonstrated by Ag-AS staining of the nucleolus organizer regions in k

A diploid chromosome number of 20 was determined from mitotic and meiotic cells from female pupae. The karyotype is comprised of a graded series of 5 pairs of metacentrics, 3 pairs of slightly smaller submetacentrics, and 2 pairs of smaller acrocentr
