Community and succession of the round-head borers (Coleoptera: Cerambycidae) infesting the felled logs of White Dhup,Canarium euphyllum Kurz
Proceedings: Animal Sciences - Tập 94 - Trang 435-441 - 1985
T N Khan
Succession and assemblage of the round-head borers infestingCanarium euphyllum Kurz have been described. The borer pests have been categorized into two major groups. The first group includes the borers of standing trees and freshly felled logs, while the second constitutes the species infesting the dead logs after some seasoning. Even among the borers belonging to each of these groups, there is a ...... hiện toàn bộ
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
Development of the incretory organs in the eyestalk of freshwater prawn,Macrobrachium kistnensis
Proceedings: Animal Sciences - Tập 91 - Trang 599-607 - 1982
M S Mirajkar, R Sarojin, R Nagabhushanam
The development of the neurosecretory cells in eyestalk is studied in zoea, juvenile and adult stages of theMacrobrachium kistnensis. In zoea, the ganglionic mass of the eyestalk compreses of three parts viz. medulla externa, medulla interna and medulla terminalis. The future sensory pore x-organ is characterized by onion bodies near medulla terminalis and a vacuole closely applied to the outer su...... hiện toàn bộ

Endocrine regulation of ovarian maturation and cement glands activity in a stomatopod crustaceanSquilla holoschista
Proceedings: 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
Terminal velocity of the first instarEctropis excursaria (Guenee) (Lepidoptera: Geometridae)
Proceedings: Animal Sciences - Tập 96 - Trang 673-678 - 1987
R Ramachandran
The terminal velocity of first instarEctropis excursaria, determined in a part mechanical part electrical apparatus, were 114±12 cm/s and 118±12·5 cm/s for two different heights. Terminal velocity decreased exponentially with increased silk lengths. For a given length of silk there wsa a significant difference in the terminal velocity of live and anaesthetised insects. The significance of these re...... hiện toàn bộ
Seedling blight of sugarcane — A new disease caused byDrechslera state ofCochliobolus spicifer
Proceedings: Animal Sciences - Tập 87 - Trang 45-50 - 1978
D V Narendra, Shantha D’DRS, M V N Setty
Sugarcane nurseries raised from fluff were found to be infected with a deuteromycetous fungus namelyDrechslera resulting in seedling blight. The causal organism was later identified asDrechslera state ofCochliobolus spicifer, The disease incidence varied from 10–30% and the seedling mortality ranged from 50–95%. Studies were conducted on isolation, symptomatology, etiology. varietal reaction, morp...... hiện toàn bộ
