Redder Ladybirds Are More Deadly
2012-02-08 04:51:39

A ladybird's color indicates how well-fed and how toxic it is, according to an international team of scientists. Research led by the Universities of Exeter and Liverpool directly shows that differences between animals' warning signals reveal how poisonous individuals are to predators. Published February 7, 2012 in the journal Functional Ecology, the research shows that redder ladybirds are more poisonous than their paler peers. The study reveals that this variation is directly linked to...

New Species Of Bamboo-feeding Plant Lice Found In Costa Rica
2012-02-07 05:08:44

Several periods of field work during 2008 have led to the discovery of a new species of bamboo-feeding plant lice in Costa Rica's high-altitude region "Cerro de la Muerte". The discovery was made thanks to molecular data analysis of mitochondrial DNA. The collected records have also increased the overall knowledge of plant lice (one of the most dangerous agricultural pests worldwide) from the region with more that 20%. The study was published in the open access journal ZooKeys. It is a...

Aphid researchers from Chinese Academy of Sciences found one new species, Aleurodaphis sinojackiae Qiao & Jiang, 2011 from Jiangsu and Zhejiang Provinces, China. It forms leaf galls on Jack trees (Sinojackia xylocarpa) and is one of two known gall makers in the plant lice Aleurodaphis (Hemiptera, Aphididae, Hormaphidinae). The study was published in the open access journal ZooKeys. Aleurodaphis was established in 1917 by van der Goot and has eight known species in the world, restricted...

A new, open-access article (DOI: 10.1603/PM10016) in the Journal of Integrated Pest Management describes the biology and ecology profiles of the soybean aphid (Aphis glycines Matsumura), an insect pest which can reduce soybean yields by $2.4 billion annually if left untreated. The authors review the invasion history and distribution of the soybean aphid, as well as its biology and the feeding damage it causes. Biological control, host plant resistance, and other factors affecting soybean...

Farmers who spray insecticides against aphids as a preventative measure only achieve a short-term effect with this method. In the long term, their fields will end up with even more aphids than untreated fields. This has been reported by researchers at the Biocenter of the University of Wrzburg in the scientific journal PLoS One. What's the status of the biodiversity in differently managed triticale fields? This is what the biologists at the Department of Animal Ecology & Tropical Biology...

Mammal's breath gives aphids cue to drop from plants to safety As soon as aphids feeding on a plant sense the heat and humidity in a mammal's breath, they drop to safety before they are inadvertently ingested together with the plant the animal is feeding on. These findings by Moshe Gish and colleagues, from the University of Haifa in Israel, show both how accurate aphids are at detecting this threat and how effective their escape behavior is. The work was just published online in Springer's...

In a case of rapid evolution, bacteria have been found to give whiteflies - crop-damaging insects of global importance - an edge over their uninfected peers, new research from the University of Arizona suggestsIn just six years, bacteria in the genus Rickettsia spread through a population of the sweet potato whitefly (Bemisia tabaci), an invasive pest of global importance. Infected insects lay more eggs, develop faster and are more likely to survive to adulthood compared to their uninfected...

An Anglo-Swiss research project has found that the impact of disease-resistant genetically-modified wheat plants on insects may be negligible. Many studies have looked at the effects of genetically-modified (GM) plants on single non-target insects. However, agro-ecosystems are characterised by numerous insect species forming food webs. This study is the first to investigate different transgenic disease-resistant wheat lines and their effect on the structure of whole aphid-parasitoid food...

Collaborative research at the University of Guam has people asking: "What IS a species" and entomologists wondering about the relationship between an insect species and the host plant or plants it feeds on. Western Pacific Tropical Research Center (WPTRC) entomologist Ross Miller has been studying aphids for years and this work has brought him in contact with entomologists in Canada and the US mainland. Aphid systemetist Robert Foottit, DNA expert Eric Maw and aphid authority Keith Pike have...

Nonindigenous insects and pathogens, including many that cause serious damage, have established in forests in the United States with regularity over 15 decades Nonindigenous insects and pathogens continue to become established in US forests with regularity despite regulations intended to prevent this, according to a study published in the December 2010 issue of BioScience. The study, by a team led by Juliann E. Aukema of the National Center for Ecological Analysis and Synthesis in Santa...

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...
