Longevity plays a significant role in determining an animal's overall health. Nutrition is a key factor that can influence an animal's longevity. Studying the relationship between wing symmetry and longevity provides a useful approach to understanding how nutrition can affect both longevity and symmetry. The effect of Pomegranate Juice (PJ) and Pom...

The population assemblage of Drosophilidae in the four districts of North Western Ghats was analysed. A total of 13,604 individuals comprising 17 species collected from 8 localities during the period of 2021–22 across various seasons. The study highlights the dominance of three species (Drosophila bipectinata Duda, D. malerkotliana Parshad & Paika...

The longevity and the climbing assay with increased density of virgin, mated, and increased number of one sex with a single opposite sex was analyzed in D. melanogaster. It revealed that the longevity of virgin single fly is more than the increased number of flies per bottle as well as mated flies. The longevity decreased less than 50% with increas...

For the first time, morphological polymorphism among the anterior and posterior sets of primary teeth of the periphallic organ was observed among natural populations of Drosophila. Natural and laboratory populations of 3 different species (D. ananassae, D. bipectinata, and D. malerkotliana) belonging to the ananassae subgroup were used to study the...

Drosophila flies were collected from areca plantations of Hegdekatta village, Sirsi taluk, Uttara Kannada District. It revealed a total of 7019 flies comprising of 12 species during 2012 to 2014. D. kikkawai Burla 1954, species population fluctuated with respect to areca harvesting period when compared to other species at different seasons. Sex com...

Drosophila flies were collected in and around Dharwad district during different seasons of 2011 and 2012. A total of 13853 individual flies comprising of 20 different species were collected by bottle trapping and net sweeping method. Maximum number (19) of species was recorded during monsoon 2012 and minimum number of species (5) during winter 2012...

Research Notes 59 such responses to stress and showed that developmental effects of lead exposure (15 ppm) in the same recombinant inbred strains assayed by Hirsch et al. (2009) significantly alters transcription at approximately 2,500 loci out of about 19,000 assayed (Ruden et al., 2009), including the cacophony locus that alters courtship song fr...

Seasonal variation of P. striata was studied from May 2010 to April 2013 in five mango plantation sites of Dharwad District. It revealed that there was an increase in population with respect to the fruiting season of mango (May and June), and it decreased after the fruiting season. The fluctuation is due to the changes in the microhabitat of the...

This study redescribes a rare species D. daruma Okada belonging to Polychaeta species group Sturtevant, of the subgenus Drosophila from Kalghatgi forest range (Western Ghats) Dharwad District, Karnataka, India. This species is for the first time redescribed from this part of the subcontinent. Their morphological characters, taxonomic status and rel...
