Puccinia psidii; (a) Symptoms on Eucalyptus grandis seedling; (b) Stem distortion and multiple branching caused by repeated infections of E. grandis, (c) Syzygium jambos; (d) Psidium guajava; (e) Urediniospores. Photos: A. Alfenas, Federal University of Viçosa, Brazil (a, b,d and e) and M. Glen, University of Tasmania (c). Common Name: Guava rust, Eucalyptus rust d e Winter Disease: Rust in a wide range of Myrtaceous species Classification: K: Fungi, D: Basidiomycota, C: Pucciniomycetes, O: Pucciniales, F: Pucciniaceae Puccinia psidii (Fig. 1) is native to South America and is not present in Australia. It causes rust on a wide range of plant species in the family Myrtaceae. First described on guava, P. psidii became a significant problem in eucalypt plantations in Brazil and also requires control in guava orchards. A new strain of the rust severely affected the allspice industry in Jamaica in the 1930s. P. psidii has spread to Florida, California and Hawaii. In 2007, P. psidii arrived in Japan, on Metrosideros polymorpha cuttings imported from Hawaii. Host Range: epiphytotics on Syzygium jambos in Hawaii, with P. psidii infects young leaves, shoots and fruits of repeated defoliations able to kill 12m tall trees. many species of Myrtaceae. Key Distinguishing Features: Impact: Few rusts are recorded on Myrtaceae. These include In the wild, in its native range, P. psidii has only a P. cygnorum, a telial rust on Kunzea ericifolia, and minor effect. As eucalypt plantations in Brazil are Physopella xanthostemonis on Xanthostemon spp. in largely clonal, impact in areas with a suitable climate Australia. -
Asparagus Pests and Diseases by Joan Allen
Asparagus Pests and Diseases By Joan Allen Asparagus is one of the few perennial vegetables and with good care a planting can produce a nice crop for 10-15 years. Part of that good care is keeping pest and disease problems under control. Letting them go can lead to weak plants and poor production, even death of the plants in some cases. Stress due to poor nutrition, drought or other problems can make the plants more susceptible to some diseases too. Because of this, good cultural practices, including a good site for new plantings, are the first step in preventing problems. After that, monitor regularly for common pests and diseases so you can catch any problems early and hopefully prevent them from escalating. Weed control is important for a couple of reasons. One, weeds compete with the crop for water and nutrients. More importantly from a disease perspective, they reduce air flow around the plants or between rows and this results in the asparagus spears or foliage remaining wet for a longer period of time after a rain or irrigation event. This matters because moisture promotes many plant diseases. This article will cover some of the most common pests and diseases of asparagus. If you’re not sure what you’ve got, I’ll finish up with resources for assistance. Insect pests include the common and spotted asparagus beetles, asparagus aphid, cutworms, and Japanese beetles. Diseases that will be covered are Fusarium diseases, rust, and purple spot. Both the common and spotted asparagus beetles (CAB and SAB respectively) overwinter in brushy or wooded areas near the field or garden as adults. -

Canada V5A IS6 The Canadian Entomologist 132: 243 - 245 (2000) An isolated stand of western white pine, Pinus monticola Dougl. ex D. Don, on Texada Island (49”4O’N, 124”1O’W), British Columbia, is extremely valuable as a seed-production area for progeny resistant to white pine blister rust, Cronartium ribicola J.C. Fisch. (Cronartiaceae). During the past 5 years, cone beetles, Conophthorus ponderosae Hopkins (= C. monticolae), have severely limited crops of western white pine seed from the stand. Standard management options for cone beetles in seed orchards are not possible on Texada Island. A control program in wild stands such as the one on Texada Island requires alternate tactics such as a semiochemical-based trapping program. Females of the related species, Conophthorus coniperda (Schwarz) and Conophthorus resinosae Hopkins, produce (+)-pityol, (2R,5S)-2-( 1 -hydroxyl- 1 -methylethyl)-5-methyl-tetrahydrofuran, a sex pheromone that attracts males of both species (Birgersson et al. -

To date, 1.5 million species of organisms have been recorded, although around 85% of potential species (some 10 million) have not yet been identified. In the case of the Neotropics, although insects are clearly a vital element, there are many families of organisms and regions that are yet to be well researched. -
