Homalodisca vitripennis (Germar) and related species have caused millions of dollars in damage to southern California vineyards in recent years through the vectoring of Pierce's disease. However, the effects of surrounding vegetation on the dispersal and distribution of H. vitripennis are poorly understood. Therefore, the relationship between dispersal rates and patch quality was tested, as wel...

Lageremia indica L. commonly known as crepe myrtle, is an ornamental plant for its attractive flowers and foliage. The fruit seeds are also to be obtained from the boot tree. aim of this study was seed morphology Lagerstroemia indica. included analyzes quality fruits several plants their different morphological methods. Research results show that Lastroemia small, dry capsules split open along ...

Transcriptome analysis was conducted in two popular Lagerstroemia cultivars: "Natchez" (NAT), a white flower and powdery mildew resistant interspecific hybrid and "Carolina Beauty" (CAB), a red flower and powdery mildew susceptible L. indica cultivar. RNA-seq reads were generated from Erysiphe australiana infected leaves and de novo assembled. A total of 37,035 unigenes from 224,443 assembled c...

air pollutants are reported to increase the specific ige response to allergens. to study allergen proteins and determine the effect of air pollutants on the allergenic potential of pollen extracts, the extracts were injected intraperitoneally and subcutaneously in guinea pigs. the results were analyzed by skin prick test (spt), elisa and sds-page followed by immunoblotting. the pollen extract o...

One hundred and twenty four plant extracts were evaluated for their antimicrobial activity against four pathogenic bacteria (Staphylococcus aureus (ATCC 8095), Salmonella enteritides (ATCC 13076), Escherichia coli (ATCC 25922), and Listeria monocytogenes (ATCC 15313)) and Candida albicans yeast (ATCC 10231) using the disk diffusion and broth microdilution methods. Of the plant extracts, fourtee...

To isolate potential insect biocontrol agents, entomogenous nematodes were surveyed in Tennessee plant nurseries in 1991. Soil samples from 113 nursery sites were baited with greater wax moth (Galleria mellonella) larvae, house cricket (Acheta domesticus) adults, lesser mealworm (Alphitobius diaperings) adults, and house fly (Musca domestica) larvae. Heterorhabditis bacteriophora and Steinernem...
