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 hypothesis has held true in the case of putative causal variants in apolipoprotein E, including "APOE" ε4, associated with Alzheimer's disease. IL23R has been found to be associated with Crohn's disease; the at-risk allele has a frequency 93% in the general population . One common form of variation across human genomes is called a single nucleotide polymorphism (SNP). As indicated by the name, SNPs are single base changes in the DNA. SNP variants tend to be common in different human populations. These polymorphisms have been valuable as genomic signposts, or "markers", in the search for common variants that influence susceptibility
