Chemical and ecological control methods for Epitrix spp.
Very little information exists in regards to the control options available for potato flea beetles, Epitrix spp. This short review covers both chemical and ecological options currently available for control of Epitrix spp. Synthetic pyrethroids are the weapon of choice for the beetles. However, the impetus in integrated pest management is to do timely (early-season) applicatio...
متن کاملQuantitative methods for ecological network analysi
The analysis of networks of ecological trophic transfers is a useful complement to simulation modeling in the quest for understanding whole-ecosystem dynamics. Trophic networks can be studied in quantitative and systematic fashion at several levels. Indirect relationships between any two individual taxa in an ecosystem, which often differ in either nature or magnitude from their direct influenc...
متن کاملConcepts and methods of ecological engineering
Ecological engineering was defined as the practice of joining the economy of society to the environment symbiotically by fitting technological design with ecological self design. The boundary of ecological engineering systems includes the ecosystems that self organize to fit with technology, whereas environmental engineering designs normally stop at the end of the pipe. For example, the coastal...
متن کاملTeaching Sampling Methods Using Ecological Examples
Ecological examples provide a rich source of material for class exercises as part of a course on sampling methods. These examples can be used for teaching the classical theory for the estimation of the parameters of a finite population, in which case they help students to learn the practical aspects of the design of studies, and the appropriate use of the standard equations for estimation with ...
