Invasion of non–indigenous insects: the impact of quarantine laws
The success rate of invasive species control programmes is usually inferred from the species identification record. However, identifications may not happen concurrently with species introductions. Some species prevented from arriving also remain undetected by authorities. This study accounts for these possibilities and provides an estimate of the historic success of quarantine laws at limiting ...

Effects of chlorpyrifos on life cycle parameters, cytochrome P450S expression, and antioxidant systems in the monogonont rotifer Brachionus koreanus
Chlorpyrifos (CPF) is a widely used organophosphorus insecticide for controlling diverse insect pests of crops. In the monogonont rotifer Brachionus koreanus, population growth retardation with the inhibition of lifespan, fecundity, and individual body size of ovigerous females was shown over 10 d in response to CPF exposure. At the molecular and biochemical levels, the rotifer B. koreanus ...

Fipronil and imidacloprid reduce honeybee mitochondrial activity
Bees have a crucial role in pollination; therefore, it is important to determine the causes of their recent decline. Fipronil and imidacloprid are insecticides used worldwide to eliminate or control insect pests. Because they are broad‐spectrum insecticides, they can also affect honeybees. Many researchers have studied the lethal and sublethal effects of these and other insecticides on ...

Diverse phage-encoded toxins in a protective insect endosymbiont
The lysogenic bacteriophage APSE infects 'Candidatus Hamiltonella defensa,' a facultative endosymbiont of aphids and other sap-feeding insects. This endosymbiont has established a beneficial association with aphids, increasing survivorship following attack by parasitoid wasps. Although APSE and 'Ca. Hamiltonella defensa' are effectively maternally transmitted between aphid generations, ...

A Brief Introduction to Insect Pheromone
Insect pheromones are compounds used to express various information such as aggregation, foraging, mating, and vigilance. Insect pheromones exist in insects in nature, and all insects produce and recognize pheromones. Insect pheromones have been widely used in pest management internationally in recent years as they are green and environmentally friendly, making fruit and vegetable safer. What are ...

Researchers model ways to control deadly maize disease
Researchers have used mathematical modelling to develop techniques to combat two co-infecting viruses causing maize lethal necrosis (MLN) in Kenya. According to researchers who conducted the new study, because maize is a staple crop in Sub-Saharan Africa, the spread of MLN is threatening food security in the region. Nik Cunniffe, a co-author and a lecturer in mathematical biology at the ...

Unlocking the Power of Oleyl Alcohol: The Secret Pheromone for Pest Management
What is oleyl alcohol? Oleyl alcohol (CAS 143-28-2) is a fatty alcohol with a chemical formula of C18H36O. It is a colorless liquid that is soluble in both water and most organic solvents. Oleyl alcohol is also known as cis-9-octadecen-1-ol or 9-octadecenol. It is derived from fatty acids and is commonly found in natural sources such as fish oils, vegetable oils, and animal fats. Oleyl alcohol ...

Pheromone Solid-phase Synthesis: A Revolutionary Advancement in the Synthesis of Pheromones
Introduction of Pheromone Solid-phase Synthesis Pheromones are a fascinating class of molecules that are used by many organisms, including insects and mammals, to communicate with one another. They are chemical signals that convey information about an individual's identity, reproductive status, and location, among other things. The synthesis of pheromones is a complex process that requires a deep ...

Spiders – the creepy crawlers we need
There are plenty of creepy, crawly pests in the world, but spiders seem to take the top spot for the most terror-inducing specimens. Although your first instinct when you see one of these eight-legged creatures scuttling around is to stomp on it, you might want to reconsider. The population of spiders is on the decline, and that poses some serious problems for their biggest threat- humans. ...

Environmental fate of emamectin benzoate after tree micro injection of horse chestnut trees
Emamectin benzoate, an insecticide derived from the avermectin family of natural products, has a unique translocation behavior in trees when applied by tree micro injection (TMI), which can result in protection from insect pests (foliar and borers) for several years. Active ingredient imported into leaves was measured at the end of season in the fallen leaves of treated horse chestnut ...

Stud case study
A major vegetable grower in Lantokia, Fiji, using soilless culture systems began to trial Amnite A-100. His crops consisted principally of lettuce, tomatoes, capsicums, cucumbers, zucchinis and melons. Before the trials they had been plagued with root diseases, mosaic virus and insect attack, control of which required constant use of pesticides and ultraviolet lighting. The first trials ...

An Assessment of Management Practices to Control Nutrient and Pesticide Levels in Vegetable Production Areas in the Rattaphum Catchment, Thailand
The over-use of agrochemicals may have adverse effects on soils along with surface and groundwater. An assessment of alternative management practices to reduce the application of agrochemicals and minimise the pollution of water resources was carried out in the vegetable agro-ecosystem in the Rattaphum Catchment. This paper details the factors that govern the volume of agrochemicals used on high ...

Application of Agricultural Biotechnology for High Nutritious Food Products
Abstract Agricultural biotechnology has some controversy impacts on global economy and international regulations. But, it has enhanced the production of crops and foods with high nutritious. Some time, it has not secured human and environmental safety, intellectual property rights, consumer choice, ethics, food security, poverty reduction and environmental conservation. Even though, it has ...

Unsound science? Transatlantic regulatory disputes over GM crops
In the risk debate over genetically modified (GM) crops, Europe's regulatory delays have often been branded as "political", i.e. not based on science. Yet the US slogan "sound science" tends to conceal value-laden features of safety claims, their weak scientific basis, their normative framing and their socio-political influences. By contrast a "precautionary ...
