“…For example, this model could apply to host species that undergo diapause during unfavorable environmental conditions, as in many disease systems with insect hosts (Delucchi, 1982;Donovan, 1991;Grant & Shepard, 1984;Takasuka & Tanaka, 2013). Similarly, host phenology could represent the start and length of time that host species are born (Campbell, 1975;Danks, 2006;Kenis & Hilszczanski, 2007).…”

“…Hosts have nonoverlapping generations and are alive for one season. The parasite,

{v}_n

, infects juvenile hosts,

{s}_n

, who are susceptible to infection, analogous to, for example, baculoviruses of forest Lepidoptera (Baltensweiler et al, 1977; Bilimoria, 1991; Dwyer, 1994; Dwyer & Elkinton, 1993; Woods & Elkinton, 1987) and univoltine insects parasitized by ichneumonids (Campbell, 1975; Delucchi, 1982; Kenis & Hilszczanski, 2007). The parasite releases new infectious progeny only after a set latency period (

\tau

), which determines the number of rounds of infection the parasite completes within a season.…”

The timing of seasonal activity, or phenology, is an adaptive trait that maximizes individual fitness by timing key life events to coincide with favorable abiotic factors and biotic interactions. Studies on the biotic interactions that determine optimal phenology have focused on temporal overlaps among positively‐interacting species such as mutualisms. Less well understood is the extent that negative interactions such as parasitism impact the evolution of host phenology. Here, we present a mathematical model demonstrating the evolution of host phenological patterns in response to sterilizing parasites. Environments with parasites favor hosts with shortened activity periods or greater distributions in emergence timing, both of which reduce the temporal overlap between hosts and parasites and thus reduce infection risk. Although host populations with these altered phenological patterns are less likely to mature and reproduce, the fitness advantage of parasite avoidance can be greater than the cost of reduced reproduction. These results illustrate the impact of parasitism on the evolution of host phenology and suggest that shifts in host phenology could serve as a strategy to mitigate the risk of infection.

“…The recovery of a single specimen of D. irritator is the first record of a parasitoid associated with SMB. A generalist idiobiont ectoparasitoid (Kenis and Hilszczanski 2004), it is found in woodland and brushy habitats from eastern North America, as far south as Costa Rica (Cancino et al 2010) and as far west as Texas (Krombein et al 1979), where it parasitizes woodboring insects (Townes and Townes 1960). Parasitoids were not a significant mortality factor in this SMB population, perhaps a result of the host's cryptic behavior, prolonged life cycle, and sparse abundance in 1 host or stand.…”

Glycobius speciosus (Say) was studied in New York State to elucidate poorly known aspects of its biology. Head capsule size from excavated larvae coupled with gallery lengths measured at the time of excavation was used to characterize larval development. Partial life tables indicated nearly 20% of G. speciosus survive to adulthood. Larvae experienced 30% of their mortality during early development, 27% during mid-larval development, and 43% during late larval development. Predation by hairy woodpeckers, Dryobates villosus (Linnaeus) (Piciformes: Picidae), the only unambiguous source of mortality, accounted for 43% mortality in naturally infested trees located and followed 2004–2009, and 74% late instar mortality. One parasitoid, Dolichomitus irritator (Fabricius) (Hymenoptera: Ichneumonidae), was recovered from a single larva. Beetles emerged between 316 accumulated DD (base 10 °C) and 648 DD. Males emerged prior to, or simultaneously with, females and lived longer. Female fecundity averaged 41.3 ± 6 eggs. Larval eclosion occurred 7–10 days after oviposition. Non-functional ovipositors observed in 16% of females represented an appreciable reproductive loss. In 77% of infested trees 1 oviposition site was located and in 70% of oviposition sites examined only 1 or 2 larvae successfully eclosed, penetrated the bark to the phloem-xylem interface, and began feeding. Beetles preferred southern and eastern aspects for oviposition which occurred preferentially on the lower bole (<20 cm). Male beetles had longer and wider antennae than females, pronotal pits containing gland pores, and a straight to concave posterior margin of the terminal sternite compared to the more rounded margin of females.

“…Natural regulators of populations of these xylophagous beetles which contribute to the dying of oak branches are members of Hymenoptera, in particular Ichneumonidae (Kenis & Hilszczanski 2004) and ants (Formicidae) as well as Cleridae, in particular Tilloidea unifasciata (Freude et al 1979).…”

Samples of dying branches from 121 trees of Quercus pubescens, Q. cerris, and Q. petraea were taken from 102 sites in Seslerio autumnalis-Quercetum petraeae and Ostryo-Quercetum pubescentis forests. After nine months' rearing in eclectors, branches were cut to 20-cm sections, and signs of infestation as well as larvae and adult insects were noted. We analysed 395 sections of branches from Q. pubescens, 125 sections from Q. cerris, and 85 sections from Q. petraea. We found 44 adult insects: 45% were from the Cerambycidae family (Callimus angulatus ssp. angulatus, Poecilium alni, and Exocentrus adspersus), 18% were from the Scolytinae subfamily (Scolytus intricatus, Xyleborus dispar), 4% from the Buprestidae family (Coraebus florentinus), 4.5% from the Cleridae family (Tilloidea unifasciata), and 28.5% from other families. In addition, 145 larvae were found: 50% from the Cerambycidae family, 39% from the Buprestidae family, 4% from the Scolytinae subfamily, and 7% from other families. Significant difference in the abundance of adult insects and larvae with regard to the diameter of branch sections and the host species were found. 78% of dying branches showed signs of infestation. Species of the Buprestidae, Scolytinae, and Cerambycidae represent important factors in the decline in oak vitality in the lower Karst region of Slovenia.
