In search for botanicals as an alternative remedy to synthetic chemicals in the pest control of tea plantations, ferns
such as Adiantum raddianum, Asplenium aethiopicum, Cyclosorus interruptus, Dicra...
Effect of two-spotted spider mite population (Tetranychus urticae Koch) on growth parameters and yield of the summer apple cv. Katja
economic injury level action threshold
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...
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...
Antenna-coupled TES bolometers for the SPIDER experiment
cosmic microwave background polarization millimeter wave instrumentation
2014/12/23
SPIDER is a proposed balloon-borne experiment designed to search for the imprints of gravity waves on the polarization of the cosmic microwave background radiation. The required wide frequency coverag...

Glass waveguides Integrated optics materials Nonlinear wave mixing
2015/5/22
We present a device for full waveform characterization, exploiting FWM in a CMOS compatible photonic chip, working with pulse energies as low as 10pJ and with sub-picosecond (<700fs) accuracy over a 1...
Entire functions for which the escaping set is a spider's web
Entire functions escaping set spider's web
2011/1/19
We construct several new classes of transcendental entire func-tions, f, such that both the escaping set, I(f), and the fast escaping set,A(f), have a structure known as a spider’s web. We show that s...
Building on recent work by Rippon and Stallard, we explore the intricate structure of the spider's web fast escaping sets associated with certain transcendental entire functions. Our results are expr...
