Orthaga exvinacea is one of the major pests of mango crop and the caterpillars defoliate the leaves and thereby reduce the crop yield. Use of synthetic insecticide is the quick method for the control this pest but its uncontrolled usage has resulted in serious lethal effects on non-target organisms and environmental pollution. Botanical insecticides are very effective, safe and...
Spodoptera litura, an important polyphagous pest, causes serious threat to a large number of economically important crops all over the world. In the present study, the quantitative analysis of aminoacids and carbohydrates in haemolymph of the last instar larvae of Spodoptera litura fed with five different host plant leaves was carried out. A comparative study of the biochemical components in the...
Motivation/Background:Cardiorespiratory interaction is known to cause a peak in the heart rate variability (HRV) spectrum, characterized as sinus arrhythmia. This study evaluates standard indexes of HRV spectral analysis with and without the influence of respiratory signal in elderly subjects with chronic obstructive pulmonary disease (COPD, N=14) and healthy lungs (N=14). In...
A study of the quantity and types of airborne bacteria and its correlation with human presence was conducted. Air samples were collected from different units for three days and three sessions (morning, afternoon and evening) for the enumeration and identification of bacterial isolates. Walk-through exercise was also conducted prior to every sampling to gather information on the number of ...
This study aims i) to determine the effect of Dundubia manifera insect sound on the stomata opening area of corn plant (Zea Mays L.) at frequencies of (in Hz) 3000, 3500, 4000, 4500, and 5000, and ii) to know the peak frequency that can optimize the stomata opening of the corn plant. The insect sound has been manipulated into peak frequencies and validated using Octave 4.2.1 ...
