Coccinellidae prey species that various Coccinellidae may attack is much wider. A genus of small black ladybirds, "Stethorus", presents one example of predation on non-Sternorrhyncha; they specialise in mites as prey, notably "Tetranychus" spider mites. "Stethorus" species accordingly are important in certain examples of biological control. They are natural predators of a range of serious pests, such as the European corn borer, a moth that costs US agriculture industry more than $1 billion annually in crop losses and population control. Various larger species of Coccinellidae attack caterpillars and other beetle larvae. Several genera feed on various insects or their eggs; for
Common disease-common variant to common diseases. Research has linked common SNPs to diseases such as type 2 diabetes, Alzheimer's, schizophrenia and hypertension. Common disease-common variant The common disease-common variant (often abbreviated CD-CV) hypothesis predicts that common disease-causing alleles, or variants, will be found in all human populations which manifest a given disease. Common variants (not necessarily disease-causing) are known to exist in coding and regulatory sequences of genes. According to the CD-CV hypothesis, some of those variants lead to susceptibility to complex polygenic diseases. Each variant at each gene influencing a complex disease will have a small additive or multiplicative effect on the
