“There can be no doubt ... that farm computerization will have as much impact as did farm mechanization decades ago.”
— Annual Review of Entomology, 1984
Arguably, the four most complex subjects in the world are seismology, meteorology, psychology, and entomology: It is not surprising that computers should be extensively employed in each of these studies. This work attempts to shed some light on the myriad ecological interrelationships of some representative insects and other invertebrates commonly of concern to North American entomologists. Not only does this study stimulate basic scientific interest; but it also forms the basis for the biological control of agricultural, structural, and medical insect pests.
Dealing with the most diverse group of life on Earth, this database necessarily omits far more than it includes (including such data as acanthocephalans as parasitic worms/medical threats and insectivorous plants as “predators” of insects). In particular, the reader is encouraged to investigate such good works as those listed as my Major References, especially for more quantitative data and considered theory than exists in this “laundry list” database. In doing so, one will also note that at least some of the data is considered suspect (even if it is not marked with a “?” in this database): In addition to filling the gaps in the data, even existing data should be independently confirmed and re-confirmed before it is given the weight of scientific fact.
As explained more fully in the database, no attempt has been made to provide comprehensive data for hyperparasites (and “hyperpredators” and “hyper-pathogens”, if you will, as well as hyper-hyperparasites, etc.): Once again, the reader is encouraged to investigate other references and conduct independent studies — under quarantined and otherwise strictly regulated conditions — to “expand the webs” and ascertain the complete impact on and by the environment for a given species in a given ecosystem.
See “Expanding ‘Food Webs of Insects and their Kin’” for adding your own data to this data base: These instructions are included not only as text on disk, accessible with this “webs” program, but also as hardcopy, for reference while modifying files on disk (Remember to make working copies of the disks first!). Incidentally, a hardcopy of any screenful of information can be generated with a standard printer by simply pressing SHIFT-PRTSC (typical for DOS software).
Please note that the numbering system employed (a 2-digit order number followed by a 2-digit family number and a 3-digit genus/species number, as indicated by “XX.XX.XXX” below) is much like your telephone number: Do not attach too much significance to it — the numbering system evolved as the project developed. Although the order numbers are in a rather generally accepted taxonomic order, the family numbers are rather randomly assigned within each order; and the genus/species numbers are very randomly assigned (as with numerous “gaps”) within each family. Just use them as they come (Prompts will instruct you if you have entered an invalid number or if, as in the case of a family with species entries but no general entry, there is “no data.”).
In researching this database, remember to consult higher taxonomic groupings (ex. 57.00.000 and 57.32.000 for 57.32.003) for possible foods/predators/threats/etc. However, be aware that an order or family entry is often more of a “catchall” than a comprehensive summary.
Because of the sheer volume of material (and my limited resources), the bulk of this database has been automatically compiled: The reader must assume some “editorial” responsibility, as by consulting taxonomic lists and alphabetical lists to account for the inevitable misspellings and redundancies (and please never hold any of my references responsible for my obvious to subtle errors!).
Finally, it is worth remembering that not all controls over insect populations consist of pathogen/parasite/predator “teams”, attacking various life stages of their hosts/prey: Such natural factors as weather as well as such artificial factors as cultural and chemical controls and pollution are, of course, very significant. However, most pest outbreaks result from disruptions in the populations of such general predators as spiders, ground beetles, or birds: By protecting such species and by introducing into ecosystems carefully selected, typically highly selective pathogens and parasites — co-evolved and co-evolving with often chemically resistant pest populations — agriculture and the rest of our society can be not only safer but also more efficient in the long-run.
