Insect monitoring traps are available for L. serricorne, which contain specific pheromones to attract male beetles, and help detect and monitor infestations. Infested bulk tobacco in the form of bales or hogsheads can be fumigated using phosphine. Methyl bromide is labeled for tobacco, but is not approved for use by Corresta.
Fogging is a technique used for killing insects that involves using a fine pesticide spray which is directed by a blower. In some cases, a hot vapour may be used to carry the spray and keep it airborne for longer. Fast-acting pesticides like pyrethroids are typically used. This is widely used for sampling or studying insects in the canopy of ...
Farmers have been using nicotine sulfate insecticide since the early 19th century. Tobacco water is produced by boiling strong tobacco in water, or by steeping the tobacco in water for a longer period. When cool, the mixture can be applied with a spray, or 'painted' on to the leaves of garden plants, where it will prove deadly to insects.
It also preserves the body colors of some insects, such as dragonflies, that would otherwise lose their color, especially if there is a liquid layer to saturate their body tissues. A disadvantage is that, although the insects are quickly stunned by ethyl acetate, it kills them slowly and specimens may revive if removed from the killing jar too ...

Synthetic repellents tend to be more effective and/or longer lasting than "natural" repellents. [1] [2]For protection against ticks and mosquito bites, the U.S. Centers for Disease Control (CDC) recommends DEET, icaridin (picaridin, KBR 3023), oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), IR3535 and 2-undecanone with the caveat that higher percentages of the active ingredient ...
Air enters the respiratory systems of insects through a series of external openings called spiracles. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system, a densely networked array of tubes called tracheae. This network of transverse and longitudinal tracheae equalizes pressure ...
Neonicotinoids, like nicotine, bind to nicotinic acetylcholine receptors (nAChRs) of a cell and trigger a response by that cell. In mammals, nicotinic acetylcholine receptors are located in cells of both the central nervous system and peripheral nervous systems. In insects these receptors are limited to the central nervous system.
