Plant products have been put to use in a variety of contexts ever since ancient times. The development chemical goods, on the other hand, led decline employment these methods against pests. Recently, there has rise concerns over public health and environmental security, which requires identification natural compounds that potential be utilized insect Mosquitoes are major transmitters illnesses ...
This is one of a series of occasional articles on therapeutics for common or serious conditions, covering new drugs and old drugs with important new indications or concerns. The series advisers are Robin Ferner, honorary professor of clinical pharmacology, University of Birmingham and Birmingham City Hospital, and Albert Ferro, professor of cardiovascular clinical pharmacology, King’s College L...
This paper is intended to provide the clinician with the detailed and scientific information needed to advise patients who seek safe and effective ways of preventing mosquito bites. For this review, clinical and analytical data were selected from peer-reviewed research studies and review articles, case reports, entomology texts and journals, and government and industry publications. Relevant in...
Sonic pest devices are tools that emit sound in the attempt to repel, deter, or kill unwanted animals such as insects, rodents, birds and large mammals. These devices, depending on the target species, cover a wide range of the acoustic spectrum from below what humans perceive (infrasonic) to above our hearing range (ultrasonic). Infrasonic is characterized as sound below 20Hz, whereas ultrasoni...
The wave forms and activity patterns of Caenorhabditis elegans were examined on agar in the presence of known chemical attractants (NaCl) and repellents (D-tryptophan), and in thermal gradients. Total activity was reduced in both attractants and repellents. Different combinations of transfers between chemicals were investigated. Two thresholds were found for NaCl: 10(-3) M NaC1 caused reduced a...
A study was conducted to compare responses of male and female Aedes aegypti (Linn.) and Aedes taeniorhynchus (Wiedemann) to 9 olfactory repellents in the World Health Organization insecticide irritability test system. An irritant insecticide (permethrin) and a control were included for comparison. Aedes aegypti exhibited significantly more takeoffs than Ae. taeniorhynchus, and female mosquitoes...
Recommendations for managing wildlife damage situations often involve application of multiple methods or techniques. The basis for such recommendations is unclear as there is little evidence that such combinations of methods work more effectively than the individual methods alone. In order to improve beyond hit or miss repellent applications, we should adopt principles exhibited in nature and d...
Background and Objective: Anopheles maculipennis is one of the most important species of mosquito that can cause serious public health problems worldwide and applying insecticides and synthetic repellents are the current methods used for its control. The continuous application of these chemicals increases the probability of resistance, reduces insecticide efficiency and causes environmental pro...
A method is described to construct magnetic fumicel packets for holding solid insect repellants (e.g., naphthalene and paradichlorobenzene) used in the herbarium. the fumicels are designed to attach magnetically to metal herbarium cabinets. they are made entirely of archival materials, and are inexpensive and easily assembled.
