Tropidurus hispidus Spix 1825 (Sauria, Tropiduridae): a new host for Oswaldofilaria petersi Bain & Sulahian 1974 (Nematoda, Onchocercidae)

No presente trabalho descreve-se a ocorrência de Oswaldofilaria petersi Bain & Sulahian 1974 (Nematoda, Onchocercidae) em Tropidurus hispidus Spix 1825 (Sauria, Tropiduridae). Um macho e uma fêmea de O. petersi foram coletados no músculo ileofibularis direito desse lagarto. Este é o primeiro relato deste hospedeiro para Oswaldofilaria spp. e também a descrição de um novo hospedeiro para O. petersi.

Pupae storage effect of Cotesia flavipes (Cameron, 1891) (Hymenoptera: Braconidae) in low temperature.

The study was developed in the 'Laboratorio de Biologia e Criacao de Insetos' (LBCI), 'Faculdade de Ciencias Agrarias e Veterinarias (FCAV), 'Universidade Estadual Paulista' (Unesp), Jaboticabal, SP, with objective of evaluating the pupae storage effect of Cotesia flavipes in low temperature (medium temperature = 2,75[degree]C). The experiment was made up of 13 treatments: fi, 1, 2, 3, 4, 5, 6, 7, 8, 9.10 and 11 masses storage days of pupae in refrigerator temperature and the check was man maintained on 25[plus or minus]2[degree]C and relative humidity of 70[plus or minus]10%. The next generation of parasitoid also was analyzed, maintained to 25[plus or minus]2[degree]C during all development. It was evaluated: period and pupae viability; average number, longevity and adults' sex ratio of the stored generation and period egg-larvae; period and pupae viability: average number, longevity and adults' sex ratio of the next generation. It verified that the pupae storage of C. flavipes in refrigerator temperature for until 5 days does not affect its development and the stored generation, suggesting the utilization possibility of this resource in mass rearing of this insect.

Composition of constitutive heterochromatin of Pseudonannolene strinatii Mauriès, 1974 (Diplopoda, Spirostreptida) analyzed by AT/CG specific fluorochromes.

Triple staining with fluorochromes (DA/DAPI/CMA) and C-banding were used to characterize the composition of Pseudonannolene strinatii heterochromatin. C-banding showed C+ bands of different labeling intensity on chromosomes 1 and 2 in some cells. Fluorochrome staining revealed DAPI+ regions corresponding to the C-banding pattern, indicating that the heterochromatin of this species is abundant in AT-rich sequences.
