When the virus is applied in a control program, large amounts are needed and the virus is slow in killing insects. Fourteen metals were tested to determine whether they could act with the virus to produce a more potent product. Cobalt chloride, zinc chloride, and ruthenium red all reduced the amount of virus need to kill gypsy moth larval and ruthenium red reduced the time required for insects to die. This information is important in understanding basic mechanisms of pathogenesis for research scientists. In addition it can serve as the basis for a successful virus formulation to use for gypsy moth control by gypsy moth managers. Technical Abstract: Fourteen cations were tested at a 1% concentration (wt:wt), as chlorides, for their effects upon the gypsy moth, Lymantria dispar (L.), nuclearpolyhedrosis virus (LdMNPV). Cupric chloride was toxic to gypsy moth larvae. Ferrous and ferric chloride were inhibitory to larval growth and development as well as to NPV. Strontium chloride was inhibitory to NPV. Six cations had little or no effect upon NPV infectivity (i.e., calcium, lanthanum, magnesium, nickel, potassium, sodium), while four cations (i.e., cobalt, manganese, ruthenium, zinc) acted as viral enhancers (i.e., LC50s were reduced). |
