2015/12/30
The effect of two-spotted spider mite populations (Tetranychus urticae Koch) on the yield and growth parameters of the early-season apple cv. Katja was evaluated during a 3-year study. In the case of ...
The Hawaiian Islands are renowned for some
of the most spectacular species radiations in the world. Most of
these radiations have been attributed to single colonization
events, although the evidenc...
Indirect effects of timber extraction on plant recruitment and diversity via reductions in abundance of frugivorous spider monkeys
Ateles geoffroyi logging Manilkara zapota
2015/11/13
The ecological effects of logging in the tropics have been analysed largely in terms of its impacts on species
diversity and abundance. However, information is very limited regarding the impact of lo...

Spider Algorithm
2015/8/26
One of the reasons complex analytic dynamics has been such a successful subject is the deep relation that has surfaced between conformal mapping, dynamics and combinatorics. The object of the spider a...
For the first time, researchers have created a visual atlas and dictionary of terms for the many strange features on the fearsome-looking jaws of a little known group of arachnids. Called camel spider...
Bifenazate, a Prospective Acaricide for Spider Mite (Tetranychus urticae Koch) Control in Czech Hops
two-spotted spider mite (Tetranychus urticae Koch) hop (Humulus lupulus L.)
2015/3/5
Bifenazate, a new selective carbazate acaricide, seems to be a very good substitute for propargite to control spider
mites (Tetranychus urticae Koch) on hops in the Czech Republic. To investigate th...
Influence of temperature and host plants on the development and fecundity of the spider mite Tetranychus urticae (Acarina: Tetranychidae)
Tetranychus urticae temperature development fecundity
2015/1/30
Temperature plays a key role in the time needed for development of Tetranychus urticae. It developed fastest at 35°C (6.50 d) and 30°C (6.93 d), while at 15°C it took 16.23 d. The higher the temperatu...
