“…One environmental condition that has consistently been shown to have a strongly negative effect on baculovirus viability is sunlight 15, 43–45. Nevertheless, baculoviruses can persist for years in terrestrial settings when protected from direct sunlight by microhabitats such as crevices in plant material or when covered with soil or forest litter 18, 44, 46, 47. It seems reasonable that aquatic sediment could provide protection to NPVs from harmful UV‐B radiation in a manner similar to litter or soil.…”

“…microbial communities, algae, diatoms, the metabolites of the various living organisms and decaying organic substances) and open channels or pores filled with water 55. It is suggested that this layer could be an important reservoir for baculovirus OBs, since these viruses are known to strongly adhere to both biotic and abiotic substrates 17, 46, 56…”

“…The model thus ignores much of what biologists have discovered can influence the course of a virus disease in an individual host. For example, host stage can affect the susceptibility (Watanabe 1987;Hochberg 1991) and infectiousness (Thompson & Scott 1979;Kaupp 1983; Teakle & Byrne 1989; Dwyer 1991a) of individual hosts. Chemical constituents of foliage consumed by hosts also can affect the susceptibility of individual hosts (Keating & Yendol 1987;Keating, McCarthy & Yendol 1990).…”

“…Addressing this question involves the search for time delays in processes that act at high density. Some viruses are long-lived and can remain infectious in the environment (Clark 1955, 1956, Jacques 1969, Thomas et al 1972, Podgwaite et al 1979, Thompson and Scott 1979, Murray and Elkinton 1989, Woods et al 1989). Populations are regulated by (positive) density dependent processes, while time delays in these processes may destabilize populations and lead to cyclic dynamics (Hutchinson 1948, Caswell 1972, May et al 1974, Berryman et al 1987, Turchin 1990).…”

Ecological Society of America is collaborating with JSTOR to digitize, preserve and extend access to Ecology.Abstract. In small-scale field and related laboratory experiments, I examined the immediate and delayed effects of nuclear polyhedrosis virus (NPV) introduction and density on the performance of Malacosoma californicum pluviale. In a factorial experiment, larvae at high density showed increased feeding and development rates and decreased reproductive potential. The introduction of NPV significantly increased per capita mortality of the host, particularly at high density, and generally reduced host reproductive potential. Adults from this experiment were mated and their offspring reared in the laboratory. Pupal mass of female offspring was influenced by treatments in the parental generation, whereas egg viability, larval development time and mortality, and pupal mass of male offspring were not. M. c. pluviale introduced to host trees the year following the factorial experiment showed no effects of previous caterpillar density on mortality or reproductive potential, as would be predicted by host-plant induction theory. An interactive effect of previous virus introduction and density on mortality was observed due to the persistence of NPV in the environment. Results are discussed in light of population dynamics and observed changes in fecundity in tent caterpillar populations.
