This handbook provides basic information about raising, handling, and maintaining cultures of bean beetles, Callosobruchus maculatus. When pupating, a larva fastens the tip of its abdomen to a part of the plant and sheds its larval skin. For many organisms which cannot internally regulate their own temperature, development is dependent on temperatures to which they are exposed in the environment. When the larva is newly-hatched, the entire body (including spines) is a bright yellow but, as they mature, the spines become darker at the tips.

Ultimately, in evolutionary terms, the purpose of bean beetles is the same as in all other living things, reproduce and leave descendants.Ecologically, bean beetles are herbivores that have specialized on seed consumption.They are a part of food webs in that eggs and larvae are prey for parasitoid wasp species (Boeke et al. Common Name: Mexican bean beetle Scientific Name: Epilachna varivestis Mulsant Authors: Louis Nottingham and Dr. Thomas Kuhar Department of Entomology, Virginia Tech Mexican Bean Beetle (MBB), Epilachna varivestis Mulsant (Fig. The soybean aphid is native to Asia. Although sedentary morph bean beetles are capable of flying, they rarely do. A very short adult life span and a larval stage in which most or all life-time feeding occurs is not unusual in insects (for example the Order Ephemeroptera, mayflies), but this life cycle seems strange compared to the dominance of adult stages in familiar birds and mammals. 55:437-477. Chi, Y.H., J.-E. Ahn, D.-J. It is found throughout Mexico and the eastern United States, and is abundant in the wetter and more heavily irrigated areas west of the Rocky Mountains. Cultures raised in a 25°C incubator (12:12 day:night light cycle) and ambient humidity (averaging 50% RH and ranging from 40%-60% RH) had generation times of 4-5 weeks. They are -inch long with eight black spots on each wing. Pupa of bean beetle. Although the seed coat of the bean is still intact, a round 1-2mm window is apparent at the location where the beetle is pupating (Figure 2c). These two morphs have very different life history characteristics such as longer adult lifespan in the dispersal morph and significantly reduced fecundity compared to the sedentary morph (Utida 1956, 1972). Integrated Taxonomic Information System. 2003), and adults may be prey for birds, reptiles and amphibians, so they do have the purpose of providing food for other organisms. As a result, they are easy to handle. 1988. Similar to many insects, Mexican bean beetle leaf damage gives the leaves a skeletonized appearance. Placing a live culture (or any beans exposed to adults beetles) in a freezer (0°C) for a minimum of 72 hours prior to disposal will ensure that beetles at every life cycle stage are dead. The head is always black. Authors: Louis Nottingham and Dr. Thomas Kuhar .
