“…A signi cant drop in the lipid content was observed on day 80 (217.16 ± 2.98 mg), which might be related to concomitant lowering of the BM due to some physiological functions, such as females having just deposited oothecae and have not yet resumed feeding. Contrastingly, Munson and Gottleib (1953) found that total lipid declined with age for adult P. americana, where females contained more lipid than males. Our ndings also deviated from earlier ndings (Munson and Gottleib, 1953;Mannix and Keley, 1980) that the highest lipid content was in 0-day-old adults and declined rapidly in the rst week of adult life, and thereafter, with some uctuations, declined slowly in both the adult male and female.…”

However, these two studies were limited to the rst week of adult life of the insects, whereas our study covered the rst 100 days of adult life.…”

An experiment was conducted on age- specific variation of body mass (BM) and lipid reserves (LR) in Periplaneta americana (L.) (Blattodea: Blattidae). The BM and LR of adult females and males of P. americana fluctuated with age and the females were heavier and loaded with more lipids than the males. The BM and LR of both female and male P. americana showed positive correlation. In an another study on relationship between adult female BM and fecundity we found that an adult female fails to produce an ootheca or does not become reproductively active, until she attains a BM of 1.27 to 1.40 g; as such, 1.27 g may be considered the ‘threshold body mass’ below which a female fails to produce an ootheca. Moreover, positive and highly significant correlations between the female BM and ootheca number (ON) (r = 0.743) and BM and ootheca mass (OM) (r = 0.747) supported the idea that females with BM above the ‘threshold’ produce healthier oothecae with heavier offspring.

“…Lipid content has been reported also as affecting the susceptibility of insects to insecticides. Munson and Gottlieb (1953) found a high correlation between lipid content and resistance of cockroaches to DDT. Bennett and Thomas (1963) showed that as percent lipid increased with age the alfalfa weevil, Hypera postica (Gyllenhal), became more resistant to heptachlor.…”

Overwintering Odontopus calceatus (Say) adults were first observed feeding on April 10. Weekly collections during the activity period indicated that new-generation adults began emerging June 4. By July 23 they had entered the forest litter for hibernation. Lipid content decreased throughout the hibernation period as the weevils utilized 77% of their total lipid content during this time. The most rapid decrease during hibernation occurred from February to March, just prior to mating and oviposition in the spring. No increase in lipid content occurred during the activity period in spring and summer. A great increase in lipid content did occur within a month after the weevils had entered the litter for hibernation. Only quantitative changes in total lipid content were determined. Odontopus calceatus (Say) was first reported from yellow-poplar, Liriodendron tulipifera L., by Glover in 1870. It was not reported as a serious pest until 1960, when it was reported damaging yellow-poplar in West Virginia (Neel and Gillespie 1966). In addition to yellowpoplar it has been reported feeding on sassafras (Needham et al. 1928) and magnolia (Smith and Weber 1951). In Tennessee yellow-poplar is the most common host. Russell and Stanley (1967) reported on some aspects of the biology and damage of O. calceatus in Tennessee. Burns and Gibson (1968) discussed the distribution, biology, systematics, life history, and damage. Adults overwinter in litter beneath host trees. In early

“…A comparison of cool temperature males with cool temperature females and hot temperature males with hot temperature females indicates no differences between the sexes in resistance to chlordane. Such differences were observed with DDT (Munson 1953b, Munson & Gottlieb 1953. Although there is no valid reason to think that DDT and chlordane have the same fundamental mode of toxic action, the above indicates that the modes of action are indeed different in the two insecticides.…”

“…The coefficient of correlation (r) for lipid quantity-survival time is +0.81. Thus if a relationship between these two exists it is significant but such a relationship still does not account for all the differences in resistance between the sexes (Munson & Gottlieb 1953).…”
