“…Nevertheless, M. chamomilla essential oil was found to be insecticidal against the pulse beetle (Callosobruchus chinensis) [27], the saw-toothed grain beetle (Oryzaephilus surinamensis, LC 50 , 3 days, = 0.59%) [28], and the desert locust (Schistocerca gregaria, 3 rd nymphal instar, LD 50 = 1.59 μg/g body weight) [29]. Chamomile oil showed potent acaricidal activity against the red spider mite (Tetranychus urticae, LC 50 = 0.65%) [30], but was less active against the cattle fever tick (Rhipicephalus annulatus, LC 50 > 8.0%) [31]. Chamomile oil, rich in α-bisabolol oxide A, has shown nematicidal activity against the parasitic nematode Anasakis L 3 with 100% mortality at an essential oil concentration of 125 μg/mL [32].…”

The essential oil of Matricaria chamomilla, collected from Nepal, was obtained by hydrodistillation and analyzed by gas chromatography -mass spectrometry. The major components in Nepalese chamomile oil were (E)-β-farnesene (42.2%), α-bisabolol oxide A (22.3%), (E,E)-α-farnesene (8.3%), cisbicycloether (5.0%), α-bisabolol oxide B (4.5%), and α-bisabolone oxide A (4.0%). A cluster analysis based on the chemical compositions of 48 samples of chamomile oil reported in the literature has revealed seven chemotypes, and the oil from Nepal represents the (E)-β-farnesene chemotype. The chamomile oil was screened for antimicrobial activity against Bacillus cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and Aspergillus niger, and toxicity toward MCF-7 breast tumor cells, Artemia salina, Chaoborus plumicornis, Caenorhabditis elegans, and Drosophila melanogaster.

“…In another study, this same group of researchers tested the effect of the Chrysanthemum coronarium L. essential oil on the T. urticae Koch and produced mortality rates of 88% and 93% on larvae and adult females, respectively [88]. In the same year, another paper was published by Afify et al (2012) [89], who tested the acaricidal activity of Chamomilla recutita L. extract on the T. urticae Koch. The LD 50 values obtained for adults and eggs in this study were 0.65% and 1.17%, respectively.…”

Tetranychus urticae Koch is a phytophagous mite capable of altering the physiological processes of plants, causing damages estimated at USD$ 4500 per hectare, corresponding to approximately 30% of the total cost of pesticides used in some important crops. Several tools are used in the management of this pest, with chemical control being the most frequently exploited. Nevertheless, the use of chemically synthesized acaricides brings a number of disadvantages, such as the development of resistance by the pest, hormolygosis, incompatibility with natural predators, phytotoxicity, environmental pollution, and risks to human health. In that sense, the continuous search for botanical pesticides arises as a complementary alternative in the control of T. urticae Koch. Although a lot of information is unknown about its mechanisms of action and composition, there are multiple experiments in lab conditions that have been performed to determine the toxic effects of botanicals on this mite. Among the most studied botanical families for this purpose are plants from the Lamiaceae, the Asteraceae, the Myrtaceae, and the Apiaceae taxons. These are particularly abundant and exhibit several results at different levels; therefore, many of them can be considered as promising elements to be included into integrated pest management for controlling T. urticae.

“…Three adult females randomly selected were transferred with a fine brush to each disk, allowing oviposition for 24 h (Afifi et al 2012;Duso et al 2008;Tsolakis & Ragusa 2008). They were always accompanied by a male to assure the fertilisation of eggs and avoid pseudo-arrhenotokous parthenogenesis.…”
