  • Basement membrane degrading proteases as insect toxins and methods of use for same
    Patent number: 6673340
    Abstract: Novel insect toxins are disclosed for use in pesticidal compositions and methods. According to the invention basement membrane degrading proteases are identified which are capable of acting as insecticidal agents. Polynucleotides are provided which include expression constructs for the expression of the recombinant insecticidal proteases of the invention as recombinant insect pathogens, as well as transgenic plants with a substantial degree of insect resistance.

  • Insect diagnostic and control compositions
    Patent number: 5643776
    Abstract: A diagnostic or control composition is useful to characterize or control insects and comprises a nucleotide sequence coding for juvenile hormone esterase (JHE). The coding sequence may be combined with a promoter sequence regulating the transcription thereof in a recombinant expression vector for use in controlling insects having a juvenile hormone esterase dependency. Preferred embodiments of the invention are recombinant baculoviruses in which a mutated JHE coding sequence provides relatively rapid speed of kill in insects.
