“…(MANSOUR et al 2004). Fruit and leaf extracts from Capparis aegyptia L., prepared with various solvents, also decreased the fecundity of T. urticae (HUSSEIN et al 2006). Reproduction of T. urticae significantly decreased after treatments with extracts of Gardenia jasminoides Ellies, Ficus carica L., and Albizia coreana Nakai.…”

Extracts prepared from 2 medicinal herbs (common sage Salvia officinalis L. and German chamomile Matricaria chamomilla L.) were used in this study for biological control of spider mites. Their effect on mortality, fecundity, and development of Tetranychus urticae Koch on English ivy (Hedera helix L.) was studied under laboratory and greenhouse conditions. The extracts were prepared by soaking fresh Salvia leaves or dry Matricaria flowers in ethanol for 24 h, followed by evaporation, and finally suspension of the pellets in water. Full extracts and extracts without phenols were tested. The Salvia extracts had a higher acaricidal activity than Matricaria extracts, but the toxicity of both extracts to spider mite eggs was low. The toxic effect of full Salvia extracts on larval stages and females of T. urticae was evident. More than 50% of larvae and females were killed by this treatment in 4 days. Besides, total fecundity of survived females was evidently lower. Mortality and low fecundity after full Salvia extract application decreased the spider mite population by 76%.The toxicity of Salvia extracts after removal of phenols strongly declined, so the negative effect of the full Salvia extract on spider mites was connected with a high concentration of phenolic compounds. The toxic effect of Matricaria extracts in all tests was much lower and no evident role of phenolic compounds in its extracts was observed.

Objective: This paper mainly determined the action modes of extract of Aloe vera L. against Tetranychus cinnabarinus Boisduval. Methods: The different action modes, contact action, repellent, fumigant, and oviposition inhibition property of the acetone extract of Aloe vera L. leaf against the carmine spider mite Tetranychus cinnabaribus (Boisduval) (Acarina: Tetranychidae) were investigated at 26˚C ± 1˚C, 75% -80% relative humidity, and 14:10 light: day cycle in the laboratory. Results: Based on the established toxicity regression line of the Aloe vera L. acetone extract against female adult mites, the median lethal concentrations (LC 50 ) were 0.836 and 0.167 mg/mL for 48 and 72 h, respectively. With processing time increased, the contact acaricidal activity increased and the repellent activity gradually decreased. The main modes of action of the extract against female adult mites were contact and repellent, and preferable effects were observed on adult mites. These results indicate that A. vera L. extract contains acaricidal and repellent bioactive components that may be useful in future control of the phytophagous mites.

“…Ten adult mites were placed in the leaf disc area which was covered with aluminum foil and received no treatment. The repellent effect was determined by calculating the percentage of adults who did not move to the treated area (Hussein et al 2006) at three assessment periods of 24, 48 and 72 h after treatment (Sivira et al 2011).…”
