in this study, the possible effects of host plant resistance on some demographic parameters and predation rate of hippodamia variegata goeze life stages have been investigated. demographic data and predation rate have been analyzed by the age-stage two-sex life table and consumption rate program. obtained results showed that preadult diuration and total preoviposition period (tpop) of ladybirds...
only The generalist predator Typhlodromalus limonicus (Acari: Phytoseiidae): a potential biological control agent of thrips and whiteflies Yvonne M. van Houten, Julietta Rothe & Karel J.F. Bolckmans ................ 237-240 Abstract: A strain of the phytoseiid predatory mite Typhlodromalus limonicus Garman & McGregor, collected from tomatoes, was tested in a laboratory study as a biological con...
abstract in order to find out a better and cheaper artificial diet for mass rearing of common green lacewing, chrysoperla carnea, an experiment was conducted using completely randomized design (crd) with 4 replications and 5 observations. in this study were used three diets [a mixture of honey, yeast and distilled water (1:1:1), a mixture of honey, yeast plus extract of angomois grain moth eggs...
We investigated effects of temperature, at 70% RH, on the reproductive parameters of the parthenogenetic psocid Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae). The lowest fecundity (21) was at 35 C and the highest (41) at 27.5 C. At 22.5, 25, and 27.5 C, peak oviposition rates (eggs/female/week) occurred in week 3 and were 4.7, 6.6, and 7.8, respectively; also 51, 57, and 62%, respecti...
here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
The limited availability of alternative foods to replace natural prey hinders cost-effective mass production of ladybird beetles for augmentative biological control. We compared the effects of powdered vs. whole Artemia franciscana (A. franciscana) (brine shrimp) eggs with or without a dietary supplement on development and reproduction of Coleomegilla maculata (C. maculata) (Coleoptera: Coccine...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
the effect of imidacloprid on the greenhouse whitefly and parasitoid wasp studied in greenhouse conditions, on lantana camara l., in a completely randomized block design with five treatments of 0.02, 0.04, 0.08, and 0.16 g/liter of insecticide and control (water) for two periods of short and long term (seven and 125 days after treatment). in short term the difference of mean of the adults’ mort...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
