Sequences of the mitochondrial cytochrome oxidase I (COI) gene of one Greek and 25 Turkish Myzus cerasi (Fabricus) (Hemiptera: Aphididae) populations collected from Prunus avium and Prunus cerasus were analyzed. The partial coding region of COI studied is 605 bp for all the populations, from which 565 nucleotides were conserved, 40 were variable, 37 were singleton, and 3 were parsimony-informative. Four haplotypes were identified based on nucleotide substitutions and the mean of intraspecific divergence was calculated to be 0.3%.

• ### Lecture Chapter 6: Supply, Demand, and Government Policies

Lecture Chapter 6: Supply, Demand, and Government Policies, In this chapter you will: A price ceiling is a legal maximum on the price of a good. An example is rent control. If the price ceiling is below the eq’m price, it is binding and causes a shortage. A price floor is a legal minimum on the price of a good. An example is the minimum wage. If the price floor is above the eq’m price, it is binding and causes a surplus. The labor surplus caused by the minimum wage is unemployment.

• ### Effect of some immunomodulators and zeatin on susceptibility of wheat to powdery mildew

The effects of zeatin, salicylic acid, and plant oligoadenylates on susceptibility of wheat seedlings to powdery mildew and the shape of dose-response curves for immunomodulation were studied. Salicylic acid and zeatin produced complex dose-responses with upregulation or downregulation of plant susceptibility. Under different experimental conditions, the dose-response curve for zeatin varied in shape from a curve with a maximum to a curve with a minimum of susceptibility to powdery mildew.

• ### Emission of methane from dead trees / snags of tropical and subtropical forest ecoregions

Methane emission from various sources of biosphere contributes to the global warming/climate change related problems. Methane release from standing dead or age old trees, a new-fangled source for emission of CH4, was investigated. The experiment was carried out in tropical and subtropical forest ecoregions of Western Ghats of India. A standardized protocol was formulated for sampling and analysis of the gas samples collected from dead/decay trees. Based on our standardized protocol maximum and minimum emission of CH4 concentration was recorded.

Investigations were carried out on fifteen cultivars of strawberry for growth, yield and quality characters. The results recorded reveal that maximum plant height (35.30cm) and number of runners (8.82) were in cultivar Catskill, however the average plant spread was found to be highest in Curaltar (34.16 cm) while cultivar Camarosa recorded maximum leaf area (42.86 cm2 ). Longest cultivar duration of bloom (85.30 days) was observed in cultivar Everly and minimum (55.38 days) in cultivar Winter Dawn.
