OBJECTIVE To evaluate the larvicidal activity of Azadirachta indica, Melaleuca alternifolia, carapa guianensis essential oils and fermented extract of Carica papaya against Aedes aegypti (Linnaeus, 1762) (Diptera: Culicidae). METHODS The larvicide test was performed in triplicate with 300 larvae for each experimental group using the third larval stage, which were exposed for 24h. The groups wer...

Feeding trials were conducted for 28days to evaluate the nutritional value of Neem (Azadirachta indica) leaf meal on the performance and economics of deep litter managed finisher broiler production. The neem leaves were harvested, air dried and milled to become neem leaf meal. It was included in the broiler finisher diets at 0,2.5,5.0,7.5 and 10% levels respectively. One hundred and fifty (150)...

Helminthiasis or infection with gastrointestinal nematodes such as Haemonchus contortus is a common problem in grazing animals which can lead to poor animal performance and economic loss to the livestock industry (Waller & Thamsborg, 2004). In Malaysia, the main methods of controlling gastrointestinal nematodes is using chemical anti-parasitic drug or anthelmintic and also by maintaining good p...

Diabetes mellitus is a metabolic syndrome characterized by an increase in the blood glucose level. Treatment of diabetes is complicated due to multifactorial nature of the disease. Azadirachta indica Adr. Juss and Bougainvillea spectabilis are reported to have medicinal values including antidiabetic properties. In the present study using invivo diabetic murine model, A. indica and B. spectabili...

Para ello, obtuvo extracto hojas tallos blandos especies antes mencionadas con solución...

In the present study, aqueous extract of eight plants, namely Azadirachta indica A. Juss, Melia azedarach Linn., Lantana camara L. Moldenke., Cannabis sativa Linn., Nerium indicum Mill., Eucalyptus sp., Ricinus communis Linn. and Solanum nigrum Linn. were tested for antifeedant and toxic effects against Pieris brassicae (Linn.). The ethanol extract of four potential plants were further tested f...

Botanical insecticides are relatively safe and degradable, and are readily available sources of biopesticides. The most prominent phytochemical pesticides in recent years are those derived from neem trees, which have been studied extensively in the fields of entomology and phytochemistry, and have uses for medicinal and cosmetic purposes. The neem products have been obtained from several specie...

Study was carried out to assess the impact of cement dust on some selected plant species around industrial area. Deposition effect of cement dust on pigmentation was studied in Azadirachta indica, Pongamia pinnata, Delonix regia, Polyalthia longifolia and Ficus religiosa. Sampling was done about 500 meter distance difference from the cement industry and measurements were taken for all the plant...

In the present study, the efficacy of 6 different species of medicinal plants belonging to 5 different families against Biomphalaria alexandrina snails and Schistosoma mansoni stages were examined. During screening test of water suspension and methanol extract, results revealed that Oreopanax reticulatum (Family: Araliaceae) had the strongest molluscicidal activity against Biomphalaria alexandr...

This work introduces a new vision-based approach for estimating chlorophyll contents in a plant leaf using reflectance and transmittance as base parameters. Images of the top and underside of the leaf are captured. To estimate the base parameters (reflectance/transmittance), a novel optical arrangement is proposed. The chlorophyll content is then estimated by using linear regression where the i...
