The detailed work of Choo et al [39] is highlighted here who report that based on their Traditional Ecological Knowledge of palm weevils ( Rhynchophorus palmarum and Rhinostomus barbirostris ) the Jotï can exercise controlled supply by deliberately felling palm trees for harvesting the larvae.…”

Throughout history humans have manipulated their natural environment for an increased predictability and availability of plant and animal resources. Research on prehistoric diets increasingly includes small game, but edible insects receive minimal attention. Using the anthropological and archaeological literature we show and hypothesize about the existence of such environmental manipulations related to the procurement of edible insects. As examples we use eggs of aquatic Hemiptera in Mexico which are semi-cultivated by water management and by providing egg laying sites; palm weevil larvae in the Amazon Basin, tropical Africa, and New Guinea of which the collection is facilitated by manipulating host tree distribution and abundance and which are semi-cultivated by deliberately cutting palm trees at a chosen time at a chosen location; and arboreal, foliage consuming caterpillars in sub-Saharan Africa for which the collection is facilitated by manipulating host tree distribution and abundance, shifting cultivation, fire regimes, host tree preservation, and manually introducing caterpillars to a designated area. These manipulations improve insect exploitation by increasing their predictability and availability, and most likely have an ancient origin.

“…Sago flour is 13% water and 1.4% protein (Groos, 1986) while raw sago is 20 to 45% water, depending on the time elapsed since production, and 0.4% protein (Ohtsuka et ai, 1984). The poor protein content of sago is well documented (Oomen, 1971;Townsend, 1974;Ulijazek, 1982) and reliance on sago is particularly risky among groups with no access to fish or other good quality protein sources. On the other hand, sago provides large quantities of food for relatively little labor; one woman can process enough sago in one day to provide 17 people with 85% of their energy needs (Townsend, 1980).…”

“…The exploitation of palm sago is a highly efficient means of provisioning a community with dietary energy, in that the energy returns per hour of work spent in subsistence can be high (Lea, 1964, Townsend, 1974, Ulijaszek and Poraituk, 1993.…”

Energy Expenditure in Sago Processing by Women in the Purari Delta of Papua New Guinea.

Palm sago is an important staple food for populations living at low density, and on marginal lands in Papua New Guinea and elsewhere in Melanesia. The exploitation of palm sago is a highly efficient means of provisioning a community with dietary energy, but has been shown to be an energetically costly activity. However, a previous estimate of the energy cost of sago making was not based on the measurement of oxygen consumption, but on an indirect prediction of it, from estimates of energy expenditure at given heart rates obtained from another study in Papua New Guinea, and controlled for body weight. In this study, the energy expenditure in sago processing among a small group of Papuan women was determined using oxygen consumption measurements in the field and compared with estimates obtained by predicting from heart rate using regressions of heart-rate against energy expenditure obtained for each woman in the study, and obtained from literature values. The energy expended in adzing sago and making sago were shown to be similarly high by the oxygen consumption method, but in neither case as high as the value obtained by predicting from heart rate and energy expenditure values given in the literature. In this first report of energy expenditure in sago processing determined by direct measurements of oxygen consumption, energy expended in sago making is shown to be lower than previously estimated.
