Stress induced alterations in the hemocyte population ofPeriplaneta americana (L.)Proceedings: Animal Sciences - Tập 96 - Trang 689-693 - 1987
N K More, Y S Sonawane
Alterations in the hemocyte population ofPeriplaneta americana (L.) during starvation and desiccation were studied for 11 days. Total hemocyte count showed increasing trend throughout the starvation period. Changes in differential hemocyte count were evident. Plasmatocytes and granulocytes decreased marginally. Increase in coagulocyte count occurred from 6th day onwards. Two-fold increase in the t...... hiện toàn bộ
Endocrine regulation of ovarian maturation and cement glands activity in a stomatopod crustaceanSquilla holoschistaProceedings: Animal Sciences - Tập 92 - Trang 399-407 - 1983
M Deecaraman, T Subramoniam
InS. Holoschista, the eyestalk is provided with four types of neurosecretory cells (NSC) while the thoracic ganglia and the brain each have three types. The activities of certain NSC types of the eyestalk (C and D), the thoracic ganglia (B) and the brain (C) show fluctuations in their secretory activity during the synchronous growth of the ovary and cement glands suggesting their involvement in th...... hiện toàn bộ
Association of ocelli with the neuroendocrine system ofTherea petiveriana (L.) (Blaberoidea: Polyphagidae)Proceedings: Animal Sciences - Tập 89 - Trang 147-153 - 1980
D Livingstone, M Rajambal
In the crepuscular fossorial roachTherea petiveriana (L.), the nerves from the pair of lateral ocelli join to form a cross bar that remains semidetached from the brain and the two nervi corporis cardiaci primus, having their association with cross bar, run posteriorly on either side of the nervus recurrens. The distribution of the neurosecretory cells and their association with the ocellar nerve a...... hiện toàn bộ
Preliminary studies on the relative growth rates of three Indian major carp hybridsProceedings: Animal Sciences - Tập 88 - Trang 209-216 - 1979
T J Varghese, B Shantharam
A comparative study of the growth rates of three Indian major carp hybrids, namely, catla-rohu, mrigal-catla and mrigal-rohu, was made. The results showed that the growth of catla-rohu hybrid was the fastest followed by mrigal-catla while mrigal-rohu hybrid exhibited the poorest growth rate. Compared to the growth of mrigal-rohu hybrid, the increases in weight of catla-rohu and mrigal-catla hybrid...... hiện toàn bộ
Antibiotic effects of resorcinol, gallic acid and phloroglucinol onHeliothis armigera Hubner (Insecta: Noctuidae)Proceedings: Animal Sciences - Tập 99 - Trang 39-52 - 1990
T N Ananthakrishnan, R Senrayan, R S Annadurai, S Murugesan
The antibiotic effects of 3 phenolic substances viz. resorcinol, gallic acid and phloroglucinol on the cotton bollwormHeliothis armigera Hubner were evaluated with particular reference to the feeding regimes, survival and pupation. Some of the characteristic antibiotic effects observed for resorcinol and phloroglucinol include reduction in consumption index and approximate digestability, increased...... hiện toàn bộ
