The cotton leafworm, Spodoptera littoralis (Boisd.), is an insect that causes serious damages to more than 112 plant species belonging to 44 different families. Botanical extracts of Ipomoea carnea were very efficient against fourth instar larvae of Spodoptera littoralis. Based on LC50 and LC90 values, Ipomoea carnea acetone extracts were recorded 24.622 and 164.947 ppm, respectively. While hexane extracts were 232.677 and 15,377.590 ppm, respectively. Also, the treatment of fourth instar larva of S. littoralis with chlorpyrifos insecticide caused 9.497 and 91.126 ppm, respectively. The chemical constituents of acetone extract of I. carnea by using GC–MS analysis resulted in the most active compounds that were palmatic (iso propyl-hexadecanoate), silane, [[(3.alpha.,5.alpha.,20R)-pregnane-3,20-diyl]bis(oxy)] bis (trimethyl-(cas)5. and pederone that recorded (44.025%, 11.455% and 9.325%, respectively). Ipomoea carnea extracts were produced with different deformation abnormalities of all S. littoralis stages.Keywords: Schistocerca gregaria, Ipomoea carnea, botanical extracts, bioassay.

Background: In Electrocardiography (ECG), the term "P-wave dispersion" (PWD) refers to variation between maximum and minimum P-waves recorded from various Electrocardiography leads. P-wave analysis in ECG may become more widely used marker in many clinical contexts as a result of improved methods for capturing and analyzing this ECG. The link between (PD) and severity of coronary artery disease (CAD) was established among personnel who had stable form of CAD. Objective: We wanted to determine if there was an association between P wave dispersion and CAD severity in patients who had stable CAD.
