The effects of saprobe and arbuscular mycorrhizal (AM) fungi on growth, chlorophyll and N, P and K content of Eucalyptus globulus Labill. growing in soil contaminated by heavy metals in the presence or absence of Glycine max were investigated. Glomus mosseae and Glomus deserticola increased dry weight, shoot length, total N, P and K concentration and the quantity of chlorophyll in E. globulus s...

Study of the dynamics and distribution of lepidopteran defoliators is important because some of them are major pests of eucalyptus. More than 3,000,000 ha of eucalyptus are now planted in Brazil even though the genus is not native there. The goal of this study was to document the frequency and constancy indexes of lepidopteran pests of Eucalyptus grandis Hill ex Maiden (Myrtaceae) collected wit...

Eucalyptus oil (EO) is an essential oil that is widely used across the globe as an over-the-counter remedy for common ailments. EO-induced seizure (EOIS) has not been recognized as an entity, and physicians rarely ask the history of exposure to eucalyptus oil when seeing a patient with first episode of seizure. Here we report 10 cases of EO inhalation-induced seizures seen over the past 2 years...

Accidental ingestion of eucalyptus oil by a 3-year-old boy caused profound central nervous system depression within 30 minutes, but he recovered rapidly after gastric lavage. The extreme toxicity of eucalyptus oil is emphasised.

Eleven species of Geothelphusa have been reported from southwestern Taiwan (Tainan, Kaohsiung and the northern part of Pingtung counties): G. albogilva Shy, Ng, and Yu, 1994; G. ancylophallus Shy, Ng, and Yu, 1994; G. caesia Shy, Ng, and Yu, 1994; G. lili Chen, Cheng, and Shy, 2005; G. nanhsi Shy, Ng, and Yu, 1994; G. neipu Chen, Cheng, and Shy, 1998; G. olea Shy, Ng, and Yu, 1994; G. pingtung ...

Eucalyptus dieback disease, caused by Cylindrocladium scoparium, has occurred in last few years in large Eucalyptus planting areas in China and other countries. Rapid, simple, and reliable diagnostic techniques are desired for the early detection of Eucalyptus dieback of C. scoparium prior to formulation of efficient control plan. For this purpose, three PCR-based methods of nested PCR, multipl...

Sir, The emergence of resistance to conventional antimicrobials is a serious problem that physicians face. This necessitates constant development of newer agents, which can inhibit the growth of or kill resistant organisms. Eucalyptus is a tall, evergreen tree, native to Australia and Tasmania, successfully introduced worldwide, now extensively cultivated in many other countries including India...

Background In vitro organogenesis is one of the key techniques associated with genetic transformation, as it determines the successful regeneration of transgenic plants after co-cultivation with bacteria. Therefore, the development of efficient regeneration protocols is the most critical step in developing genetic transformation. Protocols have been developed for several species of eucalyptus. ...

In the current study, the mosquito larvicidal activity of leaf essential oils and their constituents from two eucalyptus species (Eucalyptus camaldulensis and Eucalyptus urophylla) against two mosquito species, Aedes aegypti and Aedes albopictus, was investigated. In addition, the chemical compositions of the leaf essential oils were analyzed using gas chromatography-mass spectrometry. Results ...

A decomposition experiment using eucalyptus leaves was carried out in a Southeastern Brazilian mountain stream located at the transition between the Cerrado and the Atlantic Forest to test whether nutrient addition increases microbial and invertebrate colonisation and accelerates breakdown rates. The results show that none of the tested variables was significantly affected by nutrient addition,...
