The effects of temperature on population development of 11 species of stunt nematodes in the subfamily Tylenchorhynchinae were compared on red clover or Kentucky bluegrass in constant-temperature tanks at 5-degree intervals from 10 to 35 C. The optimum temperature for population increase on red clover in 90 days was 30 C for Tylenchorhynchus agri, T. nudus, T. martini, and T. clarus, 25 C for T...

Abstract This study determined the effects of stocking density and water temperature on rearing parameters survival larval blue bream under controlled conditions. Two experimental variants were conducted. In first experiment, reared at different densities 20, 40, 80, 120 indiv. dm −3 25°C. second larvae in 15, 25, 30°C a 40 individuals per 3 . The achieved highest growth rate lowest tested (20 ...

DOI: 10.5935/abc.20140019 In their professional practices, physicians often face unexpected situations or chance on innovative proposals and ideas. As a result of their training and competence, they usually come up with hypotheses to be tested and research is conducted. This research is completed and their results submitted for presentations at conferences as free communications. Nevertheless, ...

Temperature may affect the mobilization and hydrolysis of storage reserves for energy production during seed germination. This study investigated germination performance reserve in Dalbergia spruceana Benth. seeds incubation at 20, 25, 30, 35, 40°C. The process was favored by 25 to 35°C negatively affected 20 At there reduction speed, however, without significantly compromising final percentage...

Marasmia exigua (Butler) (Lepidoptera: Pyralidae) is one of the major rice leaffolders negatively affecting the rice production in the world. The growth and development of M. exigua was studied at seven constant temperatures (10, 15, 20, 25, 27, 30 and 35°C). The results showed that M. exigua eggs failed to hatch at 10°C and the larvae could not complete development at 15 and 35°C. The developm...

Severe obesity is associated with abnormal lipids and increased risk for cardiovascular disease. Obesity is a risk factor for vitamin D deficiency. We examined relationship between 25-hydroxy vitamin D (25(OH)D) concentrations and lipids in children with severe obesity. Medical records of 376 children were reviewed. Linear regression models and logistic regression were used to examine the relat...

The study investigates the effect of temperature on the infectivity of two entomopathogenic nematodes, viz. Steinernema sp. and Heterorhabditis indica, locally isolated from Mizoram, northeastern India, using last instar larvae of greater wax moth, Galleria mellonella, as an insect host. Two hundred infective juveniles/larva of wax moth were exposed to different temperatures, viz. 10, 15, 20, 2...

The effects of anthropogenic chemical contaminants on aquatic organisms are largely influenced by underlying environmental conditions. This study evaluated how larval rearing temperature influences the impact of malathion on the fitness of the yellow fever mosquito Aedes aegypti. Larvae were exposed to water control, and low (0.03mg/L) or high (0.05mg/L) malathion dose at 20°C, 25°C and 30°C an...

Stiretrus decastigmus (Herrich-Schaeffer) (Hemiptera: Pentatomidae) is an important predator of the insect pest Microtheca ochroloma Stal (Coleoptera: Chrysomelidae). The present study investigated the pre-imaginal development of S. decastigmus at different temperatures. The temperatures were: 20, 25, and 30 °C, with a relative humidity of 70 ± 10% and a photofase of 12 h, and the nymphs were f...
