To reduce the number of seeds released by Hakea sericea after fires, two seed-feeding insects were introduced into South Africa from Australia in 1970: a seed-moth, C. autologa, the larvae of which destroy the seeds in mature fruits, and a seed-feeding weevil Erytenna consputa, the larvae of which...

Invasive grass weeds reduce farm productivity, threaten biodiversity, and increase weed control costs. Identification of invasive grasses from native grasses has generally relied on the morphological examination of grass floral material. DNA barcoding may provide an alternative means to identify...

Cenchrus pauciflorus Benth. is one of the invasive species which is harmful to agricultural and animal husbandry production. In recent years, it has been spreading all over the eastern part of Inner Mongolia, especially in the grassland area of Tongliao, and has been posing great threat to the...

Parasitic Echinochloa colona (L.) Link has globally invaded paddy fields that could devote to severe grain yield loss. Prolonged extensive application of commercial synthetic herbicides could pose the weed evolved resistance, bioaccumulation and environmental deterioration. Hence, this paper...

To a large degree, the most serious insect and weed pests around the world are non-native, invasive species. Classical biological control, the introduction of natural enemies of invasive species to limit their populations, is a possible mechanism for alleviating the impacts of non-native pests....

Brazilian peppertree, Schinus terebinthifolia Raddi (Anacardiaceae), is an invasive weed of natural and agricultural areas of Florida, Hawaii, and Texas (USA). Biological control presents an environmentally safe and cost-effective control method for invasive populations of this weed. Though many...

The invasion history of alien Prosopis (mesquite) in Israel and Jordan is presented, with a detailed description of the introduction, background and the habitats now infested with Prosopis in these countries. While the number of escaped individuals in Israel is still limited, Prosopis has invaded...

Velvetleaf (Abutilon theophrasti Medik.) is an invasive alien species in many countries and one of the major weeds in summer row crops worldwide. Weed-management techniques that reduce weed production need to be investigated to provide new approaches. The first step in this process is the...

Eragrostis plana is a warm-season perennial grass non-native to Brazil and has become a serious weed in pasture lands of Southern South America. The objective of this work was to evaluate the influence of environmental factors on seed germination and seedling emergence. Seeds germinated at constant ...

Biological invasions have increased dramatically in the past centuries and are one of the greatest threats to biodiversity today. Chromolaena odorata, a herbaceous shrub from the Americas, is one of the most widespread and problematic invasive plant species in the tropics and sub-tropics. The plant ...
