Abstract
An insecticidal composition comprising a first composition having an effective amount of at least one species of entomopathogen distributed in a matrix. A second composition selected from vegetable oil, crop oil and partially hydrogenated oil containing mono- and di-glycerides surrounds the first composition and significantly prolongs nematode viability. The matrix is a nematode-containing macrogel or paste of partially hydrogenated oils containing mono- and di-glycerides. The macrogel matrix is selected from a continuous polymer macrogel or microcapsule-containing macrogel. Partially hydrogenated oils containing mono- and di-glycerides, (e.g., Crisco.RTM. shortening), can also be mixed with free nematodes to produce a paste formulation. Trapping nematodes in a Crisco.RTM. matrix formulation along with a water retentive polymer results in increased protection against desiccation and significantly prolongs viability during storage. An insect feeding stimulant, such as raffinose, may also be added to the mix.
