“…Eggs were incubated in environmental growth chambers at 26.7 + 0.5 ~ 60 + 5~o r.h., and under a photoperiod of L14:D10. Contact moisture for the eggs was maintained by keeping the filter paper saturated for the duration of the holding periods because rootworm eggs are reported to hatch better when constant moisture is supplied (Cunningham & Peters, 1964). Each experiment was terminated 1 wk after egg hatching had stopped.…”

“…Under such conditions, the eggs often are colonized by a species complex of fungi. Many reports indicate the serious nature of infestation of corn rootworm eggs by fungi (e.g., Cunningham & Peters, 1964;George & Ortman, 1965;Apple et aL, 1971 ;Wilde et al, 1972;Krysan et al, 1977). A large volume of literature also exists on surface sterilization of insect eggs (e.g., Martignoni & Milstead, 1960;Getzin, 1962;Ignoffo, 1963;Nettles & Betz, 1966;Rose & McCabe, 1973;Bathon, 1977;Connell, 1981;Shapiro, 1984).…”

“…Absorption of water in this species was found to be necessary for embryogenesls to be successfully completed. Cunningham and Peters (1964) had been demonstrated by Jacobsen and Christensen (1948) for the Initial stages of the denaturation of beta-lactoglobulin by urea; therefore, Hogan (1961) treated diapauslng eggs of Teleogryllus commodus with urea, on the hypothesis that diapause could be terminated by a similar process as the denaturation of beta-lactoglobulin. Although diapause was effectively broken, no conclusions were drawn as to the mode of action of the urea.…”

“…Absorption of water in this species was found to be necessary for embryogenesls to be successfully completed. Cunningham and Peters (1964) days began hatching on the 20th day after removal from the cold treatment, and continued to hatch for a period of 65 days. VJhen held at 4 C for 8l days, eggs began to hatch on the 19th day and completed hatching In 55 days.…”
