This study discusses the problem of modeling inherently positive data sets using Modified Quadratic Shepard interpolation method. There are number of scientific and business domains where data is inherently positive. For example numbers of people, mass, volume and percentage mass concentration are meaningless when negative. This interplant generates negative values while modeling such data that may cause ambiguity. We present a scaling technique that constrains the interpolant to produce non-negative graph through scattered positive data sets. |

The computing environment for web applications is dynamic and complex as internet is heterogeneous, distributed, multi-platform, multimedia, multilingual and cooperative wide area network. The web software itself is also dynamic and rapidly evolving. This complex and dynamic computing environment, complex user requirements, new features and constraints make the testing of web-based software a challenging task. Traditional testing techniques are not sufficient because they do not address the challenges associated with the web-based applications. This study reviews the techniques for the testing of web based applications and gives a strategy to use the testing techniques meeting the challenges of testing web-based software. |

Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) completed its larval stage in 17.325±0.326 days passing through six instars under laboratory protocol, 26±1°C, 60-70% RH and 16 hours' daylight. The larvae moulted for 2nd instar, two days after hatching from eggs. Average stadiel periods for 2nd, 3rd, 4th, 5th and 6th instars were 2.07, 2.15, 2.48, 3.12, 3.55 and 3.95 days respectively. The last larval stage did not moult but was contracted and shortened into grub like pre-pupal stage. The average length measured for each instar (first to sixth) was 3.4, 4.6, 9.7, 17, 28.35, 36.85 mm respectively. The average pupal period was 13.2 days for female and 15.4 days for male. Fecundity of moths fed on sucrose solution was significantly higher than water fed females. The unfed females laid few eggs none was viable. |

Experiments were conducted under laboratory conditions to find out the most efficient method for harvesting the eggs of Chrysoperla carnea from the different substrates provided on the top of the adult rearing cage for egg laying purpose. Highest egg viability (82.89%) was found in the eggs removed by a razor from the granulated Maraco paper sheet used by AM-Tech rearing methodology whereas egg viability was lowest (64.89%) in the case of egg removed from black organdy with potassium hypochlorite solution. Modest egg viability (75.56%) was observed in the eggs laid on black organdy and removed by a razor. |
