In experiments done over a period of 1 1/2 years using engorged female Rhipicephalus appendiculatus tethered in a grass plot, 42% predation was observed in long grass (40-60 cm), and 36% in short grass (6-10 cm). Deaths due to environmental factors were 4.8% and 6.8% in long and short grass, respectively. Six groups of animals were confirmed to be predators of the ticks, namely: ants, spiders, rodents, birds, lizards and shrews. The implications of these results in making tick population models, and the possibility of using predators in integrated tick-control packages are discussed
A modified iridoid (GV2) was isolated as a yellow powder in the yield of 0.3% of the dichloromethane crude extract of Gardenia volkensii fruits. It showed some antimicrobial activity on Escherichia coli with a Minimum Inhibitory concentration (MIC) of less than 20 μL of 10 mg/mL solution. The Inhibition Concentration (IC50) for for the Gardenia volkensii stem was 1166.809 mg/mL and for Doxycycline® antibiotic was 0.335 mg/mL. The stem bark IC50 was found to be 3,483 times active as compared to Doxtcycline® antibiotic, an indication that the plant can be used to treat microbial diseases though a higher dose is needed.
