“…Adults of these species oviposit either on (cone weevil and moths) or in (cone beetle) green second-year cones in spring and early summer, and their larvae mine the interior, indiscriminately devouring scales and seeds (Furniss and Carolin 1980;Hedlin et al 1981;Cibrián-Tovar et al 1986). Depending on the density or species, these insects will destroy some or all of the seeds in a cone, often trapping remaining viable seeds in damaged cones that never open (Kinzer et al 1970;Bodenham et al 1976;Schmid et al 1986aSchmid et al , 1986bPasek and Dix 1988;Blake et al 1989). Infested cones quickly die, turn reddish to dark brown, and appear stunted or deformed.…”

“…One group of specialized insects feeds on maturing seed cones and can have a significant effect on the number of viable seeds produced (Hedlin et al 1981;Cibrián-Tovar et al 1986;Pasek and Dix 1988;Turgeon et al 1994). After particularly heavy years of infestation, high cone and seed mortality can curtail recruitment of seedlings, potentially affecting the fitness of individual trees and stand dynamics (Kinzer et al 1970;Bodenham and Stevens 1981;Schmid et al 1984Schmid et al , 1986aSchmid et al , 1986bWhitham and Mopper 1985;Pasek and Dix 1988;Blake et al 1989).…”

We measured the terpenoid chemistry, cone insect distribution, and the relationship between these two parameters in the seed cones of ponderosa pine. Analyses of mono-, sesqui-, and diterpenes from four separate sites revealed high amounts of terpenoid diversity and variation. The majority of this variation occurred among trees within sites, but differences were also seen among sites and among cone clusters from individual trees. Cone insect distributions differed substantially in both time and space, with significant differences seen between two points in time and between five sites. Negative correlations existed between levels of cone insect herbivory and both a monoterpene and a diterpene factor at one site, indicating that these herbivores may be one reason that ponderosa pine maintains the high levels of chemical variation observed.

The evolution of mating systems in bark and ambrosia beetles (Coleoptera: Scolytidae and Platypodidae)

The extraordinary array of mating systems in the Scolytidae and Platypodidae has been largely overlookrd by resrarchers interested in the evolution ofsexual behaviour. This paper proipides the first overview of reproducti\ e behaviour in this important and widespread group, known to most biologists only by the reputations of tree-killing taxa.Referred to generally as 'bark beetles', these insects chew egg tunnels inside a variety of (usually deadi plant tissues, though most species are either phloeophagous (breeding in the inner bark ofwoody p h t S J or xylomycetophagoris (all stages feeding on mutualistic fungi growing on sapwood or heartwood). In most species, permanent records of many aspects of reproductive behaviour are etched in the host; in many, engra\ings reveal female fecundity, eggs sired per male, hatching success, and offspring survivorship. Each gallery arm represents a good portion of a given female's lifetime reproduction. but in many species females commonly reemerge to reproduce in one or two additional sites.In most species of bark beetles, each female initiates her own gallery, to be joined later by a male. These monogynous gallery systems are associated with mating systems defined by how long males stay with females: in a few species, males seldom ife\,erjoin females under the bark; in the vast majority of species, males stay for part or all of the oviposition period then leave to seek other mates; and a few groups exhibit permanent monogamy, in that both sexes die in their only gallery system. \VliiIc these patterns emerge from an overview of the world scolytid fauna, the length ofmale residency has seldom been quantified, and the costs arid benefits associated with male mating strategies have not been measured for any bark beetle.Male-initiated monogyny is uncommon in Scolytidae, though the rule in Platypodidae; all instances of which I am aware are summarized from a phylogenetic perspective.Inbreeding polygyny with highly biased sex ratios has arisen at least seven times in Scolytidae. These taxa are usually characterized by males being dwarfed, flightless, and uncommon. Sex determination is known for only a few examples, hut both haplodiploidy and diplodiploidv have been reported.Multiple origins of harem poly~qny (otherwise rare in invertebrates] add an exciting dimension to the comparative and experimental study ofscolytid mating systems. In harem polygynous taxa, males initiate gallery construction. I summarize what little can be learned from the literature about the fine structiire of harem polygynous mating systems in bark beetles, and the problem of measuring reproducti1.e success. Data on the nature of harem polygyny in Pityophthorus lautus are presented, illustrating ( a , the fluidity ofharems; (b) that average eggs laid per gallery arm is relatively unaffected by harem size, but strongly influenced by resource quality; (cl that male egg-gain is strongly correlated with territory quality (a consequence of (b) above); and (di the temporal patterning of immigration and emigration ...

“…Losses to insects are seldom less than 10 %, and often close to 100 % with 25 % being a crude average (Knight, 1952;Tripp and Hedlin, 1956;Lyons, 1957c;Keen, 1958;Stevens, 1959;Barnes et al, 1962;Hedlin, 1964;Graber, 1964;Merkel, 1961;Merkel et al, 1965;Kinzer et al, 1970). Every species of pine has a unique complex of insects which feed on its reproductive structures.…”

The role of insects in the dynamics of cone production of red pine

The mortality of red pine cones was studied for several consecutive years using life tables in eight different stands in the northern Great Lakes States. Usually less than 20% of a cohort of female flowers survived to maturity. Insects were the main source of mortality and were primarily responsible for annual fluctuations in the abundance of mature cones. Insects were probably also responsible, along with late summer weather (especially precipitation), for influencing the rate of initiation and differentiation of flower bud primordia, as shown in a model of the flowering-cone production processes. These studies suggest that the devastation of developing cone crops by insects may actually enhance flower primordia production and thus the future abundance of feeding and breeding sites for cone insects.
