Chlorbenside is a pesticide, also known as chlorparaside and chlorsulfacide, which is most commonly used as an acaricide being used to kill mites and ticks.
Phosmet oxon is a toxic metabolite of phosmet, a phthalimide-derived, non-systemic, organophosphate insecticide used on plants and animals. It is mainly used on apple trees for control of codling moth, though it is also used on a wide range of fruit crops
τ-Fluvalinate is a pyrethroid acaricide.1It induces tail currents in Western honeybee (A. mellifera) voltage-gated sodium channels (AmNav1) expressed inXenopusoocytes (EC50= 60 nM). It also induces tail currents in honeybee parasitic Varroa mite (V. destructor) Nav1 channels (VdNav1) expressed inXenopusoocytes (EC50= 160 nM) with a faster tail current decay than that of AmNav1 channels. Topical application of τ-fluvalinate (2 μl) in combination with coumaphos , atrazine , 2,4-DMPF, chlorpyrifos , and chlorothalonil does not affect honeybee queen mass, egg-laying patterns, or the mass of daughter worker bees at emergence.2Formulations containing τ-fluvalinate have been used to control Varroa mites in beehives. 1.Gosselin-Badaroudine, P., and Chahine, M.Biophysical characterization of the Varroa destructor NaV1 sodium channel and its affinity for τ-fluvalinate insecticideFASEB J.31(7)3066-3071(2017) 2.McAfee, A.Honey bee queen health is unaffected by contact exposure to pesticides commonly found in beeswaxSci.

Milbemycin A3 is a member of a complex family of macrocyclic lactones that contain a characteristic spiroketal group produced from the fermentation of soil bacterium S. hygroscopicus subsp. aureolacrimosus. As a compound that potentiates glutamate and GABA-gated chloride-channel opening, milbemycin A3 is used as a nematocide and insecticide. The acaricidal and nematocidal activity of a mixture of milbemycin A3 and milbemycin A4 against adult spider mites, spider mite eggs, and C. elegans are reported at IC50 values of 5.3, 41.1, and 9.5 μg/ml.
Altemicidin is a monoterpene alkaloid originally isolated fromS. sioyaensiswith acaricidal and anticancer activities.1It is acaricidal to two-spotted spider mites (T. urticae) in a greenhouse pot test at concentrations of 10 and 100 ppm. Altemicidin inhibits the growth of murine L1210 lymphocytic leukemia and IMC carcinoma cells (IC50s = 0.84 and 0.82 μg ml, respectively). It is toxic to mice with an LD50value of 0.3 mg kg. 1.Takahashi, A., Kurasawa, S., Ikeda, D., et al.Altemicidin, a new acaricidal and antitumor substance. I.
