A list of ladybird species available commercially follows below. closely related to aphids, in their diet. They include Microweisea coccidivora (Ashmead), M. misella (LeConte), and M. ovalis (LeConte) of the tribe Microweiseini, Zilus horni Gordon, Z. eleutherae Casey, Z. subtropicus (Casey) and perhaps Zagloba bicolor (Casey) (its diet is a guess) of the tribe Gordon RD. Further, Coleomegilla also includes pollen whereas Mulsantina also includes scale insects in the broad sense. Their presence indicates that natural biological control is occurring. Extrafloral nectaries may be located on leaf laminae, petioles, rachids, bracts, stipules, pedicels, fruit, etc. Figure 1. Common Name. Distribution. Now, its distribution is from Costa Rica north through Mexico to the Rocky Mountain states of the USA, and with a separated eastern population (which extends southward to northern Florida). Typically, the imported ladybird (or other organism) becomes established or does not become established; if it becomes established, it may or may not control the pest in this new situation. Widesprread. Ladybirds often use the secretions from extrafloral nectaries in their diet (Pemberton and Vandenberg 1993) and are just some of the many beneficial insects that use extrafloral nectary secretions. Scientific name: Harmonia axyridis. The Mexican bean beetle is classified as Epilachna varivestis, the squash ladybird as Epilachna borealis. Dixon AFG. They originate from countries such as China, Russia, Korea, and Japan. (1998). Because of its potential as a biological control agent of crop insect pests, several intentional introductions have occurred in the USA. Deliberate attempts to introduce that species from California in 1916-1917 to Manatee County, Florida, seem to have had no success (Frank and McCoy 1993, Hoelmer and Pickett 2003). Coccinellidae are a family of beetles belonging to the superfamily Cucujoidea, which in turn belongs to the series Cucujiformia within the suborder Polyphaga of the beetles (Coleoptera). Among the best-known and most well-loved beetles, ladybirds are easy to recognise. It is not yet clear how, or whether, they divide up the scale insects between them, because reliable prey records are too incomplete. A common North American species of ladybird beetle, the nine-spotted ladybug beetle, is orange above, spotted with black. Adults and larvae live in trees feeding on soft-bodied insects and their eggs. Nevertheless, biological control research was "bootlegged" onto other operations by dedicated researchers, was astoundingly successful, and saved California's (and later Florida's) citrus industry from ruin: there was no subsequent need to use chemicals against this pest, thus saving billions of dollars as against a trivial expenditure (about $1500 at the time, for foreign travel). Adalia bipunctata, the two-spot ladybird, two-spotted ladybug or two-spotted lady beetle, is a carnivorous beetle of the family Coccinellidae that is found throughout the holarctic region. The most familiar have bright red elytra (wing cases) with black spots, while others are black and yellow, white and brown, or even striped. Harmonia axyridis, most commonly known as the harlequin, multicolored Asian, or Asian ladybeetle, is a large coccinellid beetle. Preferred Names. This effort cannot end, because people knowing nothing about ladybird life cycles are born each minute. Harlequin ladybird. After its arrival in California, presumably as a contaminant of imported plants, it threatened to ruin California's citrus industry in the late 1800s. Annual Review of Ecology and Systematics 8: 407-427. Epilachna vigintioctopunctata; previously, Henosepilachna vigintioctopunctata. Members of the genus ; Coccinellidae, commonly known as ladybugs, ladybirds or luckybirds, are a family of beetles. After "D. pusillus" was found to be a a very useful biological control agent against sweetpotato whitefly (Bemisia tabaci (Gennadius) (Hoelmer et al. Florida Entomologist 74: 598-599. It is native to southern Mexico, but it is an immigrant to the USA, first detected in the west in 1849, and in northern Florida in 1930. Sometimes, gardeners mistake the ladybird larvae for pests and spray chemical pesticides that kill them (this is much less of a problem with growers and farmers because they have more experience). Fast ladybird facts. That is to say that gardeners, growers and farmers may benefit, at no cost, because they have no or negligible pest problems. The rub here is that the number of purchased ladybirds needed for a given pest situation may not have been worked out in detail -- it demands a huge amount of practical experience to tie down the details for at least hundreds of situations.
