As the instars develop, they shift from sucking aphid liquids as meals to eating the entire insect. Range length 6.50 to 7.8 mm 0.26 to 0.31 inĪfter emergence from the egg, a larva will remain with its egg casing, eat it, and eat any infertile eggs in the vicinity.( "Coccinella septempunctata L.", 2011 Cantrell, 2011) Its size is approximately the size of the adult Coccinella septempunctata. It has a hardened exoskeleton which develops from the fourth instar. The pupa is slate grey to black, sometimes having white or orange markings on the outside. ( "Coccinella septempunctata L.", 2011 Angalet, et al., 1979 Beverley, et al., 2012 Cantrell, 2011) Size increases with each consecutive molting. septempunctata can be variable in color depending on temperature but are generally dark and highly segmented. ( "Coccinella septempunctata L.", 2011 Cantrell, 2011 Hodek and Michaud, 2008) The eggs of Coccinella septempunctata are small (1mm long) and oval-shaped. The ventral side of the abdomen is convex and is almost exclusively black males have slight hairs on the last abdominal segment. This species also has two characteristic pale white spots along the anterior side of the pronotum. The three spots on each elytra are variable in placement, but are generally rather bold. There is one spot next to the scutellum that bridges the junction between the two elytra there are two white patches on either side of the scutellum, just above this black scutellar spot. This species typically has seven black spots on its elytra (although it can range from 0 to 9). It can be identified however, by several distinct characteristics. Range elevation sea level to 1500 m to 4921.26 ftĬoccinella septempunctata looks like the quintessential ladybug: it is medium sized, has orangish-red elytra and black spots.( Cantrell, 2011 Hodek and Michaud, 2008 Hoebeke and Wheeler, 1983 Honek and Martinkova, 2005 Honek, et al., 2007 Turnock, et al., 2003) The preferred overwintering habitat for Coccinella septempunctata is an open area with sheltering boulders, small tussocks, or hedgerows of densely packaged grasses that are south-facing, maximizing sunlight hours. This normally includes small herbaceous plants, shrubs and trees in open fields, grasslands, marshes, agricultural fields, suburban gardens and parks. ( Gordon, 1985 Honek and Martinkova, 2005 Maredia, et al., 1992)Ĭoccinella septempunctata can be found wherever significant numbers of prey, particularly aphids, are present. Since then, this species has become one of the most common and widespread coccinellid species in the Nearctic range. and Canada, either purposefully or unintentionally in the following years. Populations continued to arise in the eastern U.S. However, this population was thought to have arisen from an accidental release. None of these releases were thought to be successful in creating a natural population until 1973 when an established population was found in Hackensack Meadowland, New Jersey. for biological control of crop threatening aphids. septempunctata occurred between 1951 to 1971 in the U.S. Therefore, natural enemies have a great opportunity as biological agents for controlling soybean pests and diseases and as an alternative to replace the use of chemical.Coccinella septempunctata originated in Europe and Asia, but is now found throughout the Middle East, India and North America (U.S. which survived on field applied with biopesticides is quite abundant. Oxyopes sp., Coccinella sp., Sycanus sp., Andrallus sp., Rhynocoris sp., Paederus sp., Entomobrya sp., Aphidius sp., Binodoxys sp., Encarsia sp., Trichogramma sp., and Telenomus sp. However, the application of chemical can kill natural enemies. The application of biopesticides by inundation is safer and can maintain the survival of natural enemies and can reduce yield losses. The results showed that biopesticide applied by inundation can suppress Sclerotium rolfsii, Phakopsora pachyrhizi, Xanthomonas axonopodis, and Spodoptera litura. Biopesticides applied were Trichoderma harzianum (Trichol 8), neem seed powder, entomopathogenic virus SlNPV (Virgra), entomopathogenic fungi Beauveria bassiana, and eugenol from clove oil. The study was conducted in Banyuwangi, East Java. This research aimed to study the impact of biopesticide inundation on soybean pests and diseases. They are effective for controlling pests and diseases as well as suppress the resistance and resurgence. Biopesticides are biological agents derived from plant metabolites and microorganisms. Soybean pests and diseases are quite abundant and have shown the resistance to chemical pesticides.
