Green lemons safe from fruit fly

Importers\u27 demands for fruit imports to be free of local pests places great restrictions on the movement of fruit between States, between countries, and sometimes within a State. In Western Australia a Fresh Fruit Disinfestation Committee was formed in 1969 to direct State research aimed at developing techniques for post-harvest fruit sterilsation Programmes are supported by State and Federal funds and, in W.A., have provided staff and facilities to work on Mediterranean fruit fly. Parallel work with Queensland fruit fly and codlin moth is being done in New South Wales and Victoria

Thrips damage of grapes

IN mid-December, a few bunches of Semillon grapes were submitted for examination from a Caversham Vineyard. Damage to grape berries by thrips has not been recorded before in Western Australia

Adenosine deaminases acting on RNA (ADARs): RNA-editing enzymes

Adenosine deaminases acting on RNA (ADARs) were discovered as a result of their ability extensively to deaminate adenosines in any long double-stranded RNA, converting them to inosines. Subsequently, ADARs were found to deaminate adenosines site-specifically within the coding sequences of transcripts encoding ion-channel subunits, increasing the diversity of these proteins in the central nervous system. ADAR1 is now known to be involved in defending the genome against viruses, and it may affect RNA interference. ADARs are found in animals but are not known in other organisms. It appears that ADARs evolved from a member of another family, adenosine deaminases acting on tRNAs (ADATs), by steps including fusion of two or more double-stranded-RNA binding domains to a common type of zinc-containing adenosine-deaminase domain

Prospect Theory and Tenure Reform: Impacts on Forest Management

We examine the role of risk and time preferences in how forest owners respond to forest certification. We test hypotheses from a two-period harvest model derived from prospect theory in the context of Fujian, China, where new forest certification started in 2003. Using survey and field experiment data, we find that certification resulted in reduced harvesting, and the effect was larger for households who are more risk averse and exhibited distorted probability weighting. In contrast, loss averse households increased harvesting after certification. These findings suggest that diverse individual preferences may be a source of impact heterogeneity for forest certification
