Abstract:
... An explicit means of calculating the expected number of species [E(Sₙ)] and the variance of (Sₙ) in a random sample of n individuals from a collection containing N individuals and S species is presented. An example illustrates a new use of E(Sₙ): determination of the sample size required for any desired degree of accuracy in collecting species known to occur in a particular area. ...

Abstract:
... When larvae of the tenebrionid beetle, Zophobas rugipes, were allowed to disperse among 26 equivalent chambers in a circular dispersarium, distribution patterns were found to be a function of larval weight and number of larvae in the apparatus (N). Small larvae (x wt 250 mg) were significantly aggregated while larvae mature larvae (1000 mg) where highly overdispersed. Medium larvae were intermedia ...

Abstract:
... Induction of precocious metamorphosis in the bug Oxycarenus lavaterae by application of precocenes on third instar larvae is reported. Compounds used were precocene 1 (P1), precocene 2 (P2) and ethoxyprecocene 2 (EP2). EP2 proved to be the most active compound eliciting 100% of precocious adults at 10 μg dose; P1 was inactive at the doses tested and P2 was clearly less active than EP2. Precocious ...

The inhibitory effects of 200 μM aminooxyacetic acid (AOA), cobalt sulfate (CoSO,) and norbornadiene (1000 μ 1·1⁻¹) on the AgNO₃₋ induced developmental alterations in Gynura aurantiaca DC plants are evaluated. AOA and COSO₄ dramatically repress ethylene production. Norbornadiene does not affect ethylene synthesis. At the same time the development of leaf malformations and the accumulation of the l ...

Abstract:
... In insects, 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA) synthesizes mevalonate for the production of nonsterol isoprenoids, which are essential for growth and differentiation. To understand the regulation and developmental role of HMG-CoA reductase, we have cloned a full-length HMG-CoA reductase cDNA from the cockroach Blattella germanica. This cDNA clone was isolated using as a prob ...

Abstract:
... The corpora pedunculata, or mushroom bodies (MBs), in the brain of Drosophila melanogaster adults consist of approximately 2500 parallel Kenyon cell fibers derived from four MB neuroblasts. Hydroxyurea fed to newly hatched larvae selectively deletes these cells, resulting in complete, precise MB ablation. Adult flies developing without MBs behave normally in most respects, but are unable to perfor ...

HAL2 encodes a 3'(2')5'-bisphosphate nucleotidase that serves to remove the end products of sulfate transfer during cellular metabolism. The enzyme is inhibited by lithium and sodium and is activated by potassium. Metabolic systems that are sensitive to salt, as well as those go ...

It is 5,749 nucleotides long and encodes an amino acid sequence of 1,862 residues (including a putative signal peptide of 17 residues). The vitellogenin sequence includes a long serine-rich stretch between amino acids 322 and 349, and two other stretches between amino acids 1691 and 17 ...

A cDNA encoding an Arabidopsis homolog for gamma-GT was overexpressed in tobacco (Nicotiana tabacum) plants. A high level of the membrane-bound gamma-GT activity was localized outside the cell in transgenic plants. The overproduced e ...

In the fat body of adult Blattella germanica females, the expression of 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CoA reductase) during the first reproductive cycle is parallel to that of vitellogenin, suggesting a functional link between the mevalonate pathway, and vitellogenesis and reproduction. We have studied the effects of compactin and fluvastatin, two inhibitors of HMG-CoA reductase, o ...
