The development of testes occurs in the abdomen during fetal life, after which they migrate into the scrotal sacs during the third trimester. During their descent, they may get arrested anywhere along the tract. Risk of testicular cancer is higher in patients with undescended testes, abdominal testis being more prone than inguinal. Seminoma is the commonest… (More)
The new species Menacanthus palmai collected from Coturnix coromandelica (Gmelin), in Rampur district (UP), India, is described and illustrated. Morphologically the new species is close to M. abdominalis from Coturnix coturnix but differs in having long pointed ventral processes on the postero-medial angles of the second to fifth pleurites. Furthermore,… (More)
Intruders damage or steal valuable information by either bypassing security tools or penetrating through them, necessitating the need to detect such intrusion attempts especially in case of multi-event based distributed attacks spanning over a considerable amount of time. In this paper ecology of agents is being suggested that uses class hierarchy to define… (More)
The prevalence, intensities of infestation, range of infestation and population composition of two phthirapteran species, Ardeicola expallidus Blagoveshtchensky (Phthiraptera: Philopteridae) and Ciconiphilus decimfasciatus Boisduval and Lacordaire (Menoponidae) on seventy cattle egrets were recorded during August 2004 to March 2005, in India. The frequency… (More)
The population structure of Bovicola caprae on goats has been recorded by examining 57 goatskins (45 by brushing cum searching and 12 by dissolving method). Population composition, sex ratio, adult nymph ratio has been recorded at different levels of infestation. The female dominated over the male population and male: female has been found to be 1:2 by… (More)
The vagina in poultry lice, Lipeurus lawrensis tropicalis PETERS, is a simple cup-shaped structure but is complex in its internal organization. It is divisible into anterior, central and posterior part. The anterior tubular part is deeply sunk into the posterior cup-shaped one due to the invagination of the central part. The space thus formed probably… (More)
The alimentary canal of Lipeurus lawrensis tropicalis Peters has the three typical regions but differs from that of other species of Mallophaga in some respect. The posterior region of the mid-gut is slightly broader in female than in male. The mid-gut was found to have higher epithelium not in the anterior two-thirds but in the anterior one-third and in… (More)
Oenocytes of Lipeurus lawrensis tropicalis Peters, an ischnoceran Mallophaga (Sens. Lat. Phthiraptera) occur either singly or in clusters of 2-6, and do not exhibit any changes in the different stages of nymphs and adults of the 2 sexes.
