Three new whitefly species, Trialeurodes rex Martin sp. nov., T. bruneiensis Martin sp. nov. and Metabemisia palawana Martin sp. nov. are described from fern hosts in Sulawesi, Borneo and Palawan, respectively. An annotated check list of whiteflies feeding on pteridophyte hosts worldwide is presented, including host records and geographical distribution. A table is presented, comparing the names of fern hosts from literature with their current status.

Palm Weevil

The date palm is a cultural and economic heritage of many nations. The red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera, Curculionidae) is among the world’s most serious insect pests of palms that have rapidly expanded its geographical distribution and host plant range during the last decades. Integrated pest management (IPM) is followed to suppress the pest using the most economical and least hazardous methods to humans and the environment. Since R. ferrugineus is a serious pest of date palm production worldwide, farmers, researchers, and scientists have developed many tactics to eradicate this pest. However, there was no published article covering and integrating the current status, biology, ecology, and future control tactics of R. ferrugineus and proposes an IPM program. Therefore, in this review, R. ferrugineus geographical distribution, host plant range, economic importance, infestation symptoms, morphology, biology, and its management tactics were thoroughly discussed. These tactics include early detection of R. ferrugineus infestation, trapping, chemical applications, use of bio-agents, bioinsecticides (plant extracts), resistance cultivars, cultural practices, sterile insect technique, gene silencing technology, quarantine, and geographical information system. In conclusion, all available control tactics suggest that R. ferrugineus could be successfully managed by developing IPM programs comprising several means of control. It is hoped that this review will highlight some aspects of date palm management and raise research gaps and directions deserving further investigations to develop a better understanding of R. ferrugineus management and therefore contributes to the sustainability of date palm cultivation worldwide.

Abstract A description is provided for Fusarium oxysporum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pleurivorous in soil. DISEASE: Fusarium oxysporum occurs chiefly as a soil saprophyte and appears to survive winter in the mycelial or chlamydospore state. Numerous strains of this species are serious wilt pathogens of many crop plants. These together with saprophytic strains have the ability to live almost indefinitely in soil with the result that normal rotational cropping is not a practical control measure. Because of the importance of many of these physiologic strains to the plant pathologist and because of the immense amount of research that has been carried out in relation to their control, separate description sheets have been prepared dealing with the history, distribution and control measures of certain 'formae speciales'. GEOGRAPHICAL DISTRIBUTION: world-wide.

Plant Storage

The most important harvested organs of crop plants, such as seeds, tubers and fruits, are often described as assimilate sinks. They play little or no part in the fixation of carbon through the production of sugars through photosynthesis, or in the uptake of nitrogen and sulphur, but import these assimilated resources to support metabolism and to store them in the form of starch, oils and proteins. Wild plants store resources in seeds and tubers to later support an emergent young plant. Cultivated crops are effectively storing resources to provide us with food and many have been bred to accumulate much more than would be required otherwise. For example, approximately 80% of a cultivated potato plant's dry weight is contained in its tubers, ten times the proportion in the tubers of its wild relatives (Inoue & Tanaka 1978). Cultivation and breeding has brought about a shift in the partitioning of carbon and nitrogen assimilate between the organs of the plant.

Numerical Errors

An examination of some specialized lunar and planetary ephemerides has revealed inconsistencies in the adopted planetary masses, the presence of non-gravitational terms, and some outright numerical errors. They should be considered of temporary usefulness only, subject to subsequent amendment as required for the interpretation of observational data.
