Frankliniella spp. (Thysanoptera: Thripidae) thrips damage a variety of crops, feed on a broad range of hosts, and often migrate into cropping systems from adjacent vegetation. To determine potential sources of Frankliniella spp. thrips on crops, annual cycles of abundance of Frankliniella occidentalis (Pergande), Frankliniella fusca (Hinds), Frankliniella bispinosa (Morgan), and Frankliniella ...

Three soilborne viruses transmitted by Polymyxa betae KESKIN in sugar beet have been described: Beet necrotic yellow vein virus (BNYVV), the agent of rhizomania, Beet soilborne virus (BSBV), and Beet virus Q (BVQ). A multiplex reverse transcription-PCR technique was developed to simultaneously detect BNYVV, BSBV, and BVQ, together with their vector, P. betae. The detection threshold of the test...

Chenopodium ambrosioides is an important medicinal plant widely used in the traditional medicine all over the word. Its folk medicinal uses include its antidiabetic profile. A study was designed to determine its hypoglycemic effect. mice used in experiment were fed with high-fat diet for two weeks before induction of Diabetes mellitus by injection of streptozocine (STZ). Animals treated with cr...

This study aims to detect the antischistosomal properties of the plants' Chenopodium ambrosioides, Conyza dioscorides and Sesbania sesban methanol extract against Schistosoma mansoni in infected mice, including determination of total protein and albumin levels and the activities of alanine and aspartate transaminases (AlT, AsT) and acid and alkaline phosphatases (AcP and AkP) enzymes in the ser...

The toxicity and mutagenic potential of most African plants implicated in the management of cancer have not been investigated. The ethanolic extracts of selected Nigerian plants were subsequently studied using the brine shrimp lethality tests, inhibition of telomerase activity and induction of chromosomal aberrations in vivo in rat lymphocytes. Morinda lucida root bark, Nymphaea lotus whole pla...

Present study was conducted to explore the herbicidal effect of volatile essential oil of Mentha longifolia (L.) L. and Chenopodium ambrosioides L. against Avena fatua L. weed. A significant effect of essential oil was observed on early seedling growth, chlorophyll content and cellular respiration over a concentration range of 0.01 – 0.25 mg/ml as compared to control ones. More inhibition was o...

Seven seed borne fungi were isolated from sugar beet seeds viz. Alternaria alternata, Helminthosporium sp., Rhizopus stolonifer, Epicoccum sp., Rhizoctonia solani, Phoma betae and Fusarium oxysporium f. sp. betae. The last three fungi were found internal, while the others were external on seed surface. The internal fungi caused root-rot disease to sugar beet plants. Tre11tment of seeds with eac...

In countries where leishmaniasis is endemic, there are not very many treatment alternatives and most options have problems associated with their use. Plants and their natural products constitute good sources of interesting lead compounds that could be potentially active against Leishmania. Chenopodium ambrosioides is a plant that is widely used in popular medicine and its antiparasitic effects ...
