Comparação das características e medidas ultrassonográficas das glândulas adrenais de cães e gatos filhotes saudáveis

The aim of the study was to analyze and compare the ultrasound characteristics of adrenal glands between healthy puppies and kittens by establishing standards of normality and references. Fifteen healthy crossbred puppies with mean weight of 3 kg and fifteen healthy crossbred kittens with mean weight of 2 kg, aged between five and six months, participated in the study. The animals were submitted to ultrasound exam of adrenal glands for visualization of their internal characteristics. The frequency of visualization of adrenal glands was 100% in kittens. In puppies the frequency was 75% for the right gland and 100% for the left gland. The puppy's adrenal gland, both right and left, were bigger in length (1.08 ± 0.01 cm, 1.11 ± 0.01 cm) and width (0.42 ± 0.02 cm, 0.45 ± 0.01 cm) in relation to kittens' adrenal gland length (0.64 ± 0.01 cm, 0.63 ± 0.01 cm) and width (0.30 ± 0.02 cm, 0.34 ± 0.01 cm). The adrenal gland of puppies and kittens was hypoechogenic to the surrounded fat, delimited by a hyperechogenic line and without distinction of the cortical and medullar region. The ultrasound dimensions of length and width of the adrenal glands, both right and left, were the same in puppies and kittens. The right and left puppies' adrenal glands were longer and wider than the kittens' glands.

Biological aspects of Aphis gossypii Glöver, 1877 (Hemiptera: Aphididae) on colored lint cotton cultivars

This paper outlines the results of a study into the biological aspects of Aphis gossypii Glöver on colored cotton cultivars through the construction of life tables. In addition, we evaluate the influence of density of gossypol glands and trichomes of leaves on the biology of the aphid. Tests were conducted in a climate chamber at 25 ± 2°C, with relative humidity (RH) at 70 ± 10%, and a photophase of 12 hours, using the cultivars BRS Rubi, BRS Safira, and BRS Verde. Newly hatched nymphs were individually isolated in petri dishes containing leaf discs of cotton cultivars on a layer of water-agar (1%) of approximately 5 mm thick. An evaluation of the trichomes and gossypol gland densities of the cotton leaf plants was performed under a stereomicroscope, delimited to an area of 1 cm², and a count and identification of those on the surface was made. The feed substrates that were evaluated influenced the nymphal stage of A. gossypii. BRS Verde provided the shortest duration and BRS Safira was the longest during this phase. The cultivar BRS Verde, with the lowest density of trichomes, provided a large number of nymphs and led to a higher net reproductive rate (R0). Given these results, conclusions can be drawn that the colored cotton cultivars influence the duration of nymphal and adult stages of A. gossypii. The cultivar with a high density of trichomes on leaves (BRS Safira) adversely affects the fertility parameters of A. gossypii.
