Figure 2 represented a log-probit plot of the observed inhibition of purified bovine erythrocyte acetylcholinesterase as a function of concentration for several of the transformation products of aminocarb. The observation that these inhibition curves are parallel suggests a similar mechanism of interaction for the various derivatives. The parameter I5f. (the concentration of inhibitor required to achieve 50% inhibition oi the enzyme activity) for each of the inhibitors were calculated and are recorded in Table 1. These values are reported relative to the parent compound aminocarb = 1. Also included in Table 1 are the relative toxicities of several of these products to house crickets (Acheta domesticus). It had been our intention to develop bioassay tests using the target insect itself, the eastern spruce budworm (Choristoneura fumiferana). However, spray tower results were quite variable and it was considered that genetic variability of the stock culture made the production of uniform test batches difficult to achieve. Using the house crickets, an LD q of 130-155 ppm for aminocarb standard was observed over the course of more than 25 bioassays. Also included in Table 1 are observations by Abdel-Wahab and Casida (19) using human plasma or house fly head cholinesterases. 

While the vast majority of alkenes reported on the surface of insects are straight-chain molecules, there have been a few reports of methyl-branched alkenes. Warthen and Uebel (1980) found (Z)-2-methyl-24-hexatriacontene in the hydrocarbons of the house cricket, Acheta domesticus. Carlson and Schlein (1991) reported 19,23-dimethyltriacont-l-ene and other homologs in tsetse flies. Howard et al. (1990) found a homologous series of...

In addition to the L. maderae myotropic peptides, a series of five myotropic peptides were isolated and structurally characterized from head extracts of the cricket, Acheta domesticus. with the same purification system and bioassay (Holman, G. M., et al. Chromatography and Isolation of Insect Hormones and Pheromones, in press.). The structures of these five myotropic peptides, the achetakinins, are shown in Table 1. Like the leucokinins, the achetakinins (Ak s) contain a C-terminal pentapeptide core which is responsible for the myotropic activity (12). In Ak s III and V, the C-terminal pentamer is the same as the leucokinin pentamer (Phe-X-Ser-Trp-Gly-NH2, where X = Asn, His, Ser, or Tyr) but in Ak s I, II, and IV a slightly different pentamer (Phe-X-Pro-Trp-Glv-NH is present. 

Diuretic peptides promote diuresis in insects in different ways. The chapter reviews the isolation and chemical identification of diuretic peptides from three insects Locusta migratoria, Manduca sexta, and Acheta domesticus. The biological activities of the characterized peptides are discussed.

Fig. 2. Alignment of apoLp-lII sequences. The amino acid sequences of apoLp-IlI from Acheta domesticus (Ad, house cricket), Derobrachus geminatus (Dg, palo verde beetle), Locusta migratoria (Lm), and Manduca sexto (Ms) were aligned by the method of Feng and Doolittle (1987). The positions of the five helices in the L. migratoria apoLp-III are indicated. (e) Conserved residues (o) hydrophobic residues.

The (myo) kinin family of peptides is especially a very interesting one, because its members have two very different functional activities in insects. The first members of this family were originally isolated on the basis of stimulation of the cockroach hindgut in vitro from extracts of whole heads of L. maderae [151]. This species contains 8 isoforms of kinins. Shortly after their first isolation, it was reported that these kinins also stimulate diuretic activity of isolated Malpighian tubules of the yellow fever mosquito Aedes aegypti [175], This function of kinins has now been shown regularly in conspecific diuretic assays with a number of other insect species. To date, the structure of kinins (see Table 5) have been fully elucidated in insects from the American cockroach (8 isoforms), the house cricket, Acheta domesticus (5 isoforms), the migratory locust (1 isoform), the mosquitoes, Culex salinarius and A.

An interesting recent study (Gaylor et al., 2012) showed house aickets (Acheta domesticus) provided with free access to polyurethane foam with 8.7 wt. % of penta-BDE as well as uncontaminated food for 28 days accumulated substautial body bur-deus of 13.4mg/kg of EDC. Even with food and water available ad libitum, the crickets still ingested PBDE-contaminated foam and showed no apparent distress despite the high body burdens. However, effects on the larval stages and the role of these as vectors for PBDE transfer have not been investigated.
