Among social Hymenoptera, the development of the laborer position has arrived at its peak in the ants, wherein some taxa have advanced complex physical laborer position frameworks. Various specialist rank frameworks can be created through guideline of three parts of larval development: basic size, development parameters, and reinventing of these elements. Indeed, even the most unpredictable position frameworks could have developed basically by the expansion of amended projects as far as possible of a hereditary formative pathway for laborers. Laborer...
Competition is one of the fundamental dynamics of community ecology and has been defined ‘the hallmark of ant ecology’ by Hölldobler and Wilson (1990). Effects of competition can influence the ant community structure in different ways: determining which species will have access to the different resources, defining which species can coexist in the same community, and possibly establishing dominance hierarchies. The competition for resources can occur through two main mechanisms: interference and exploitation competition (Parr and Gibb 2010). In some...
We often think of ants as a nuisance and a pest in our gardens and home but few take the time to observe or get to know more about ants. A well-known SouthAfrican Poet and philosopher Eugene Marais said ‘Go to the Ants you Lazy person, observe his ways and become wise’ (roughly translated) He spent a lot of time observing the ants and noted everything he found carefully down and eventually wrote a book called ‘The soul of the...
Fire ants can attack most of Australia’s shoreline regions and big regions of the tropical west of Australia, including world heritage fields and national parks. Fire ants are very violent and prey on creatures living on the floor like insects, frogs, reptiles, birds and mammals. As a consequence, some of Australia’s indigenous livestock, including endangered birds, could be displaced or removed. Fire ants are also a threat to native plants because they eat and damage seeds and seedlings, as well...
Abstract Ants have been proposed as a sustainable alternative to pesticides in conventional agriculture, as they supposedly possess some intrinsic defense mechanisms against infections, that might be utilized in protecting farmed plants against pests and pathogens. Previous studies on ant-associated plants have shown an increase in herbivore damage and pathogen infection following exclusion of some naturally occurring ants. However, the actual mechanisms of protection against pathogens remain unknown, and thus the utility of adding ants to plants not usually associated...
