The development, survivorship, longevity, reproduction, and life table parameters of the Asian citrus psyllid, Diaphorina citri Kuwayama were evaluated at 10°C, 15°C, 20°C, 25°C, 28°C, 30°C and 33°C. The populations reared at 10°C and 33°C failed to develop. Between 15°C and 30°C, mean developmental period from egg to adult varied from 49.3 days at 15°C to 14.1 days at 28°C. The low-temperature...

-1. In Caiman crocodilus, the pH of the gastric secretions during digestion may reach 1.2 in specimens kept between 20 and 30°C. C. crocodilus feeds and digests at 15°C, but the pH of gastric secretions did not drop below 1-8. 2. The gastric secretion increased in rate and hydrochloric acid concentration after injections of histamine (400 t~g/kg body weight, given in four hourly doses). The rat...

The effects of temperature and inoculum density of Fusarium oxysporum f. sp. ciceris race 5 on suppression of Fusarium wilt in chickpea (Cicer arietinum) cv. PV 61 by seed and soil treatments with rhizobacteria isolated from the chickpea rhizosphere were studied in a model system. Disease development over a range of temperatures (20, 25, and 30 degrees C) and inoculum densities (25 to 1,000 chl...

A series of studies were conducted to assess the effect of increasing environmental temperatures on redox status and endocrine responses in crossbred cattle under simulated conditions. In present study four non-lactating crossbred cattle were exposed to 25, 30, 35 and 40°C temperature with relative humidity of 40-50% in psychrometric chamber for 5 hours/day from 10:00 to 15:00 hours for 21 days...

Background: Groundnut bud necrosis virus (GBNV) (Tospovirus genus, Bunyaviridae family) infects the major crops of solanaceae, leguminosae and cucurbitaceae in India. Temperature is an important factor which influences the plant growth and development under diseased conditions.Objective: In the present study, we evaluated the effect of four different temp...

Francisella noatunensis subsp. orientalis (Fno) (syn. F. asiatica) is an emergent warmwater fish pathogen and the causative agent of piscine francisellosis. Although Fno causes septicemia and can live extracellularly in infected tilapia (Oreochromis spp.), the early interaction of Fno with vasculature endothelium is unknown. In the present study, we examined the interaction of wild-type Fno (WT...

this study investigated the effect of loading and temperature on anaerobic co-digestion of poultry manure with straw in mesophilic conditions. the study was made at lab-scale using 70l reactor with a hrt of 15 days. during the first phase, different loads of 1.0, 2.0, 2.5, 3.0, 3.5 and 4.0 kg vs/m3.d were studied in order to produce biogas. at load of 3.0 kg vs/ m3.d, vs removal and gas product...
