Johns Hopkins researchers revealed how mosquitoes and other insects taste DEET - a man-made compound that's been the most widely used insect repellent for more than 50 years - and smell citronellal
, a commonly used botanical repellant.
One group of rats (Group CIT-CONT) was exposed to 132 [micro]l citronellal
that was reapplied after every 4 subjects.
In this context, citronellal
(CT) is a monoterpene present in the essential oil of several aromatic plants, such as Corymbia citriodora and plants of the gender Cymbopogon, as C.
Caryophyllene [beta] and citronellal
of Lemon balm were affected by the treatments (Table 2).

But, he says, the widely promoted 'Citrosa' geranium, which is the so-called "Mosquito Plant," appears to contain only small amounts of citronellal
and is not likely to be any more effective as a mosquito repellent than other rose geraniums.
The control group had 132 [[micro]liter] of citronellal
(citronella), reapplied after every 4 subjects.
In preliminary lab studies, the most potent have been clove oil and citronellal
, which is derived from sources such as lemons and lemon grass and is the active ingredient in the citronella candles common around summer picnic tables.
neesiana fruit, such as Z-citral, eucalyptol, citronellal
, [alpha]-pinene and [beta]-pinene, are reported to possess potential antimicrobial activity against Staphylococcus aureus and Candida albicans at non-cytotoxic doses in human keratinocytes (Comai et al.
Major components of oil were citronellal
2010), however, quantitative differences were observed for citronellal
, geraniol, citronellol and limonene.
Classes of oil components in various fertilizer treatments revealed that oxygenated monoterpenes (rosefuran, linalool, citronellal
, isogeranial, rosefuran epoxide, neral, geranial, methyl geranate, geranyl acetate) constituted the highest level of components (73.
