CONTEXT Insects can be the cause of major ecological problems; they can transmit microbes and parasites that affect humans, and damage food crops, trees, and homes. The total economic cost of insect-related damage and disease is immeasurable. In traditional Iranian medicine (TIM), several medicinal plants have been identified as insecticides or insect repellents, but many of them are still unkn...

To the Editor: Lyme borreliosis is the most common vector-borne disease in Sweden, and as many as 10000 individuals are thought to be affected each year.1 Recent studies have suggested that individual variability in vector attachment may be linked to different body odors.2,3 Other studies suggested that diethyltoluamide is the best repellent against insect vectors and permethrin against ticks, ...

The increase in insecticide resistant mosquito populations necessitates the exploration of novel vector control intervention measures. Push-pull strategies for insect control have been successful when used in integrated crop pest management. Through the combinatory use of deterring and attracting stimuli, the abundance of insect pests can be changed in a given area. A push-pull strategy might a...

In recent years, the common bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), became a major public health concern in urban communities. Bed bugs are notoriously difÞcult to control, and their bites are not tolerated by most people. The public has an urgent need for materials and methods to reduce bed bug introduction and bites during work, travel, or sleep. A repellent product will help ac...

OBJECTIVE To determine the effectiveness in reducing malaria of combining an insect repellent with insecticide treated bed nets compared with the nets alone in an area where vector mosquitoes feed in the early evening. DESIGN A double blind, placebo controlled cluster-randomised clinical study. SETTING Rural villages and peri-urban districts in the Bolivian Amazon. PARTICIPANTS 4008 indiv...

Laboratory experiments were carried out to investigate the efficacy of sugarcane bagasse-based lignin against four stored grain insect pests viz., Tribolium castaneum, Tribolium confusum, Sitophilus oryzae and Callosobruchus maculatus. Mortality was assessed after 24, 48 and 72 h of treatment and LD50 values were calculated at the respective time intervals. It was observed that T. castaneum is ...

In this article it is claimed that in order to obtain the right composition, structure, and functionality for a new product, one needs to anticipate what the demand of the product will be and take into account all costs involved (associated manufacturing and supply chain). To obtain the demand, one needs a pricing model, which in turn relies on consumer preferences that are connected to the pro...

BACKGROUND The worldwide threat of arthropod-transmitted diseases, with their associated morbidity and mortality, underscores the need for effective insect repellents. Multiple chemical, botanical, and "alternative" repellent products are marketed to consumers. We sought to determine which products available in the United States provide reliable and prolonged complete protection from mosquito b...

Insect repellents are important prophylactic tools for travelers and populations living in endemic areas of malaria, dengue, encephalitis, and other vector-borne diseases. DEET (N,N-diethyl-3-methylbenzamide) is a 6-decade-old synthetic repellent, which is still considered the gold standard of mosquito repellents. Mosquitoes use their sense of smell to detect DEET, but there are currently two h...
