α-Costic acid, a plant sesquiterpene with acaricidal activity against Varroa destructor parasitizing the honey bee

Alessio Cimmino et al.

Summary: The organic extract of Dittrichia viscosa showed significant acaricidal activity against Varroa destructor, with alpha-costic acid being identified as a toxic compound for the parasite mite. This suggests a potential use of alpha-costic acid to control Varroa mites without any harmful effects on honey bees. Additionally, the absolute configuration of alpha-costic acid could be reliably determined through DFT computational analysis of chiroptical spectra.

Toxicity of essential oils obtained from Juniperus thurifera var. africana and Mentha suaveolens subsp. timija chemotypes against pre-adult stages of Hyalomma aegyptium tick (Acari: Ixodidae)

Laghzaoui El-Mustapha et al.

Summary: This study compared the acaricidal activity of two essential oil chemotypes obtained from Mint Timija and Incense Juniper against immature stages of Hyalomma aegyptium ticks. Results showed that the chemotype rich in pulegone and menthone from Mint Timija exhibited the highest toxicity, while the piperitone-rich chemotype showed the weakest activity. On the other hand, Incense Juniper's sabinene-rich oil displayed relatively moderate activity against the ticks' eggs.
