Immunohistochemistry and biological statistics were used to investigate the expression of the c-kit protein in four representative phases of spermatogenesis of three dominant species of locusts of Arcypteridae (Orthoptera: Acridoidea), namely, Omocestus viridulus (Linnaeus), Euchorthippus unicolor (Ikonn.), and Euchorthippus vittatus Zheng, and so on, in Siping area of Jilin Province, China. The results revealed the following: (1) There was weak positive expression of the c-kit protein in spermatogonia and the positive granules were thinner; (2) there was a strong positive expression of the c-kit protein in primary spermatocyte and the positive granules became the largest than in all developmental stages; (3) the c-kit protein positive expression became stronger in secondary spermatocyte, while the positive granules became thinner; (4) there was strong positive expression of the c-kit protein and the positive granules were thinner in mature sperm, which were distributed on its head and tail; (5) there were strong positive protein granules massing at the end of spermary; (6) the positive intensity of the c-kit protein in spermatogenesis was significantly different among different species of locusts. The data suggested that the c-kit protein may play a crucial role in spermatogenesis as well as maintain the physiological action of sperms and fertilization, regulate the developmental speed of spermatogenesis, and/or maintain species isolation, etc.展开更多

Their presence ranges from southeastern Mexico and has so far been confirmed only in tropical habitats. This publication seeks to highlight the current and potential challenges associated with their presence. For decades, the use of chemical insecticides has been the primary method for controlling locust populations, though these substances pose significant risks to human health and the environment. Recent research efforts are directed toward developing control methods that are less detrimental to both ecological and human health, such as biopesticides derived from pathogenic fungi, plant extracts, and strategically prescribed burns. Satellite surveillance enables the monitoring of the origination and progression of outbreaks to inform control strategy selection.展开更多

This paper is based on the data measured in the typical weather of the growth season, from 1998 to 2000, with the LI 1600 Steady Porometer and the general weather information. The daily variation of transpiration in black locust forest ( Robinia pesudoacacia L.) is modeled by Penman Monteith equation. As a result of the model, a continuous daily transpiration in the growth season was calculated. The net radiation, intercepted by black locust forest canopy, was acquired from a semi empirical equation of measuring net radiation R n with the extinction coefficient k and leaf area index LAI . The canopy integral stomatic resistance is a mimesis with an empirical equation of measuring data. Compared with measuring data, the relative error of the modeled ones is less than 12% averagely. At last, the total transpiration of black locust forest during the period of 1998 and 2000 in the growth season of May to October, as an average transpiration of the different density stands, were 192 46, 187 07 and 195 59?mm respectively.展开更多
