The potential of middle eastern flora as a source of new safe bio-acaricides to controlTetranychus cinnabarinus, the carmine spider mite

Action modes of Aloe vera L. extracts against <i>Tetranychus cinnabarinus</i> Boisduval (Acarina: Tetranychidae)

“…This finding is similar to the repellent and oviposition inhibition activities of Azadirachta indica A. Juss against Polyphagotarsonemus latus female mites [14,15]. Mansour et al [3] examined 29 kinds of local plant species with T. cinnabarinus, and found that 16 species have repellent and reproduction inhibition activities. The biological activity and seconddary metabolism of plants, as well as repellent and reproduction inhibition activities, have received more attention than other modes of action.…”

“…Pesticide abuse can also lead to the eradication of natural enemy insects and damage to the ecological balance, which result in the problems of resistance, resurgence, and residue. Therefore, the key to comprehensive mite control is to choose an acaricidal agent that is selective, environment friendly, and able to undergo natural degradation [3].…”

The role of phenols in the influence of herbal extracts from Salvia officinalis L. and Matricaria chamomilla L. on two-spotted spider mite Tetranychus urticae Koch

“…Essential oils can be responsible for a high toxicity of many plant extracts to mites, e.g. extracts prepared also from some other species of Labiatae, Origanum onites L., Thymbra spicata L., or Mentha spicata (MANSOUR et al 2004;SERTKAYA et al 2010). A strong lethal effect on spider mites (KUMRAL et al 2010).…”

“…Plants with a high concentration of phenols are often less attractive hosts for many herbivorous insects and mites than plants with a low content of these secondary metabolites. (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).…”

The efficacy of crude aqueous extracts of some plants as grain protectants against the stored grain mite, Rhizoglyphus tritici

“…Exposure-interval-dependent variation in the percent efficacy of all tested plant extracts against mites may be attributable to the longer exposure of mites to treated grains, which increases the probability of contact of mites with the treated grains and, ultimately, with the toxic compound(s) of plant extracts.
