U.S. scientists seeking to avoid using pesticides in controlling soybean aphids are considering genetically modifying soybeans to prevent aphid damage. Iowa State University Professors Bryony Bonning and Allen Miller say if their research is successful, soybeans will carry in-plant protection from aphids, similar to the way genetically modified corn now keeps the European Corn Borer from reducing corn yields. The researchers said their goal is to support development of technologies with...

Two Iowa State University researchers are examining a new method of controlling soybean aphids without the use of chemical pesticides. Bryony Bonning, professor of entomology, and Allen Miller, professor of plant pathology and director of the Center for Plant Responses to Environmental Stresses, are looking at a way to genetically modify soybeans to prevent damage from aphids. If the research is successful, soybeans will carry in-plant protection from aphids, similar to the way genetically...

 This year farmers in the Midwest are growing a new variety of soybeans developed by University of Illinois researchers that has resistance to soybean aphids. However, in addition to the resistant plants, U of I researchers also discovered a new soybean aphid which is not controlled by this resistance.Soybean aphids made their first appearance in North America in the summer of 2000, resulting in tremendous crop losses for farmers. U of I researchers began immediately searching for a...

The cowpea or black-eyed pea, as it is more commonly known, is a New Year's tradition for good luck. But disease and particularly aphids, which can wreck a crop within a few a days, are especially bad luck for the cowpea, according to scientists. Several new lines of cowpeas with genes that are aphid-resistant and less susceptible to disease are currently being tested by researchers with Texas AgriLife and other Texas A&M System entities."The cowpea has been an important and popular food...

U.S. entomologists say a careful choice of nitrogen-fixing bacteria might provide soybean farmers protection against an invasion of soybean aphids. Pennsylvania State University researchers said soybeans are legumes -- plants that can have a symbiotic relationship with nitrogen-fixing bacteria called rhizobia and therefore do not need additional nitrogen fertilizer. Each type of legume -- peas, beans, lentils, alfalfa -- have their own rhizobia. Soybeans are from Asia and so there were...

A U.S. agriculture economist says the fight against the destructive soybean aphid is a success that will pay big dividends during the coming years. Michigan State University Professor Scott Swinton says state and federal governments have spent $17 million on soybean aphid research and education since 2003. Swinton said the net economic benefit of that integrated pest management work should reach $1.3 billion during the next 15 years. This is an example of what a good payoff you can get as a...

Although ecologists expect many species will be harmed by climate change, some species could be buffered by their potential to evolve or by changes in their surrounding ecosystems. Researchers at the University of Wisconsin-Madison and the University of Arizona are using a common agricultural insect pest to understand how ecological and evolutionary factors drive population shifts in the face of a changing environment. A study appearing March 6 in the journal Science shows that both...

According to findings that have been published in Proceedings of the Royal Society B, an aphid species has "soldiers" who often die in the process of repairing damage to galls, the homes that aphids force their plant to grow.The aphids gather around a hole in the gall and squeeze out a fluid comprising two-thirds of their body size, using their legs to mix it and form a "scab".The presence of the aphids after the scab formed is the only possible way for full recovery of the plant tissue to...

By Adlam, John Whitefly With predators, add Majestik, Nemolt, SB Plant Invigorator and Mycotal into your integrated pest management programme. Mycotal is a useful control product especially in humidity levels above 80 per cent under protection. If predators are not used, apply Gazelle, Oberon, Toppel 10, Decis or Gyro. Spraying three times at five-day intervals to ensure all subsequent generations are controlled gives the best adult control programmes. Exempter or lmidasect 5GR granules in...

Aphids or greenfly, plant lice (superfamily Aphidoidea) are small plant-feeding insects (1 to 10 mm). Of the 4,000 species of known aphids (distributed in 10 families), around 250 are serious pests for agriculture and forestry as well as an annoyance for gardeners. Natural predators include ladybirds, hoverfly larvae and lacewings. Aphids have two compound eyes and two ocular tubercles made up of 3 lenses, each of which is located behind and above the compound eyes. They have 2 tarsal...

The soldier beetles (Cantharidae) are relatively soft-bodied, straight-sided beetles. They are closely related to the Lampyridae, or firefly family. Some are important predators of aphids during their brief adulthood.

Flower-flies (also known as hover-flies) are a family of flies (Diptera), with the scientific name of "Syrphidae". As their names suggests, they are most often seen around flowers. The adults feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In certain species, the larvae are saprophytes, eating decaying plant and animal matter in the soil or in ponds and streams. In others, the larvae are insectivores and prey on aphids, thrips, and other...

Ladybirds, also known as ladybugs or lady beetles are a family, Coccinellidae ("little sphere"), of beetles. The name is thought to allude to the Blessed Virgin Mary in the Catholic faith. Ladybirds are found worldwide, with over 4,500 species described - more than 450 native to North America alone. Ladybirds are small insects, ranging from 1 mm to 10 mm (0.04 to 0.4 inches), and are usually yellow, orange, or red with small black spots on their carapace, and black legs, head and feelers. As...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
