Peltophorus adustus is reported for the first time in Mexico, on Agave vivipara (=Agave angusfolia) and A. cupreata (Asparagaceae). Adult weevils were found attacking the agave seed pods, and larvae fed in seeds of these agaves. The damage to the seed pods and seeds of Agave by this weevil are...

Alien plants from psammophilous ecosystems have been studied in southern Spain. Sixteen sites, which are included in the Andalusian Network of Protected Spaces, have been chosen along 1100 km of Andalusian coasts in order to verify the degree of abundance and influence of these species on different ...

Invasion by alien species is nowadays considered as one of the major threats to biodiversity. Thus, the identification of the areas exposed to a greater risk of invasion represents a priority for management purpose, especially in presence of habitats worthy of conservation. This paper aims to...

The introduced shrub flora in Rwanda was analyzed and the risk of invasion was assessed based on the species' purposes of introduction. The results showed that more than half of invasive alien shrubs in Rwanda were introduced as ornamentals. They include Agave americana L., Bryophyllum proliferum...

Capsule: Flowers of an invasive plant species are more visited by native birds than flowers of ornithophilous endemic plants. Aims: To describe the bird guild and its behaviour visiting the century plant Agave americana in an insular environment and to determine which factors are affecting...

Invasion biology is an important element of global environmental change and represents one of the main threats to biodiversity. American species were introduced to Tenerife after the Spanish conquest during the eighteenth century, as is the case for Agave americana and Opuntia dillenii. The long...

In 2012-14, agave (Agave americana) plants with leaf spot symptoms were observed in Mazandaran, Iran. Initial symptoms consisted of 3-5 mm dark brown spots, circular to ovoid, enlarging to 3.5-10 cm in diameter. Large lesions often coalesced. The causal pathogen was identified as Alternaria...

In spring 2013, a disease of A. tequilana was observed in Tala (Jalisco, Mexico), which greatly reduced its availability for tequila production. Affected plants showed extensive chlorosis, followed by yellowing and necrosis of stem and leaf tissues. As the disease progressed, leaves collapsed and...

The study area is rich in plant diversity but there is an urgent need of conservation. Some rare and endangered plants are still found abundantly in the region, but without protection these plants may become endangered in the near future. Endangered plant species have been categorized by the IUCN...

The gray pineapple mealybug, Dysmicoccus neobrevipes Beardsley, is an invasive pest that during recent years has caused serious damage on Sisal (Agave sisalana Perrine) crops in South China. The biology of D. neobrevipes including its development, survivorship, longevity and reproduction was...
