Investigation effect three diets on life table parameters Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae) under Laboratory Conditions

Abstract

The common green lacewing, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) is best-known as biocontrol agent. The suitability diet was important in mass-rearing and releasing field. C.carnea has a serious role at IPM cultures apposite of aphid and whitefly pest. For this purpose, Schizaphis graminum (Rondani) (Hemiptera: Aphididae), Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) biotype-B 3 rd nymphs stage and Semi artificial diet as prey for Life table parameters was evaluated. All experiments were conducted at 25 ± 5 0 C, 60± 5% RH and photoperiod of 16:8 (L:D).This study, the collected data was analyzed by using Jack Knife model and SAS (9.1) soft ware and experimental design was formatted Completely Randomized Design (CRD) and comparison among means followed by Tukey's HSD post hoc test. The highest Lx (number of individuals alive between age x and x+1) and the lowest d x (numbers dying during the age interval x) were 0.99 and 0.005 (%) that belonged semi artificial diet. Reproductive and stable population parameters such as Net Fertility rate, Net reproductive rate (R 0 ), Gross reproductive rate (GRR), Intrinsic of increase (r m ), Mean generation time (T c ) and Doubling time (DT) in aphid, whitefly and semi artificial diets were 244.9±4.

Using a Two-Sex Life Table Tool to Calculate the Fitness of Orius strigicollis as a Predator of Pectinophora gossypiella

“…However, there are many factors that affect the fitness traits of predators such as prey quality, density and temperature [10,11]. Voracious or keen prey is also an important factor [11][12][13][14] that affects the development or fitness of predators [9,[15][16][17][18][19][20][21].…”

Effect of Eggplant Varieties and Temperatures on Development and Fertility Life Tables of Chrysoperla carnea (steph.) (Neuroptera: Chrysopidae)

“…(Neuroptera: Chrysopidae), is considered one of the most efficient predators that found in several corps around the world (Abdel-Salam, 1995). This predator is successfully employed to control population of aphid species in various agroecosystems (Easterbrook et al, 2006;Jokar and Zarabi, 2012). It is also a successful predator in mass rearing programs especially in hot spot areas (e.g.…”

“…Life table parameters are fundamental component in ecological studies and general biology (Alasady et al, 2010;Jokar and Zarabi, 2012). Information regarding the growth, survival, and reproduction of an insect at various environmental conditions is fundamental to its management (Mandour, 2010).…”

“…The influence of aphid species on biology and life parameters of chrysopid species is discussed by several authors (El-Serafi et al, 2000;Sattar et al, 2011;Jokar and Zarabi, 2012;Khuhro et al, 2012;Hameed et al, 2013). The effect of temperature is also discussed in many researches works of temperature and varieties on the life table (Saljoqi et al, 2015;Pathan et al, 2016).…”

Rearing of Adult Green Lacewing, Chrysoperla carnea (Stephens) on Different Artificial Diets in the laboratory

“…However, when C. carnea larvae were reared on nymphs of Shizaphis graminum, Bemisia tabaci as well as artificial diets, significant impact was determined on fecundity, larval duration, hatchability and sex ratio (female/male). During the scarcity of natural foods the artificial diet is the best source for mass rearing of C. carnea [6]. The present research work was conducted on different artificial food supplements for mass rearing of C. carnea adults in the laboratory.…”
