.... and 12:12 light: dark, photoperiod) during 2012. Results revealed that P. solenopsis successfully and significantly (P<0.05) completed its life cycle along with highest body weight gain on China rose followed by potato. Moreover, P. solenopsis had the best survival (34.2 ± 3.8 days) and reproduction (7.8 ± 0.4 nymphs/adult female) when separated and kept without food from their respective host plants. China rose therefore seems to have the p...

...dm;C, 75% RH and 12:12 h photoperiod. Instar 3rd responded with 100% mortality at 5x107 conidia ml-1, while same level of mortality was recorded in 5th instar at 1x108 conidia ml-1. Instar 5 also showed the lowest mortality (33.3%) at 1x106 conidia ml-1. Median effective concentration (EC50) ranged between 9.87x105 and 21.30x105 conidia ml-1 for 3rd to 5th instars. Median effective time (ET50) ranged between 3.3 days and 8.2 days for different tested concentr...

...cues, as temperature and photoperiod, play important roles in animals’ physiological adjustments. In order to determine the contributions of temperature and photoperiod to seasonal changes in body mass and thermogenesis in Apodemus chevrieri, we examined seasonal-acclimatized and lab-acclimated animals on several physiological, hormonal, and biochemical markers indicative of thermogenic capacity. The result...

...ext-align: justify;">The photoperiodic effects on vegetative growth and flower quality of Zinnia (Zinnia elegans Jacq.) were examined during 2015 at the Horticulture orchard, Sindh Agriculture University Tandojam in a three replicated RCBD design. The zinnia plants were grown under four photoperiodic treatments which included T1=Natural photoperiod (Control), T2=4 hours daylight (8 am -12 ...

...gulation under different photoperiods in Eothenomys miletus, body mass, food intake, serum leptin levels and hypothalamic neuropeptide neuropeptide Y (NPY), Agouti related peptide (AgRP), pro-opiomelanocortin (POMC), cocaine and amphetamine regulated transcript (CART) expressions were measured. The results showed that short photoperiod reduced body mass and body fat mass, and increased food intake. But serum leptin le...

The fungicide was orally administered at 5 and 10 mg/Kg body weight/day for 10 consecutive weeks.Testicular volume and weights were measured weekly, whereas semen quality, and histopathological profile were investigated at week 10.The obtained results reveal that under a long photoperiodthe sexual activity of the control lasted only 04 weeks, characterized by significant incre...

...R.H.) with 14:10 h (L:D) photoperiod using cotton mealy bug as a host. According to the results, the immature duration and adult longevity were comparatively longer at lower temperature (24 ± 0.5 °C) and shorter at higher temperatures. Among population dynamic parameters, net reproductive rate (R0) was 216.52, 105.99 and 27.07 off-springs per individual, intrinsic rate of increase (r) was 0.1543, 0.1600 and 0.1518 off-spring...

...as seen in June when the photoperiod and temperatures were highest, while the lowest GSI was seen in October (0.09±0.01). The start of the monsoon rains was a cue for final maturation and spawning and by the middle of July; the testes were already declining and reached the minimum point in October. Both photoperiod and temperature have a strong influence on completion and regression of the spermatogenesis. This detail...
