The pea aphid (Acyrthosiphon pisum Harris) is known to be a pest of significant economic importance and is widely dispersed in Chile. Nowadays, the pest management is oriented to a limited utilisation of synthetic insecticides and by this way avoid the development of insect resistances. There are many alternatives to achieve this objective such as the biological control. The plant growth-promoting rhizobacteria (PGPR) are soil organism that increase rates of plant growth but which can also have an effect of biological control on pest insects. The objective of this thesis is to assess if the PGPR-induced plant defence’s has an effect on different APA populations (Acyrthosiphon pisum with alfalfa host-plant). The population parameters, and the feeding behaviour were studied. Moreover, the plant responses were also measured (hormone profile analysis, and photosynthesis and morphological parameters). For all the experiments, broad bean (Vicia faba L.) plants were previously inoculated with the PGPR Bacillus amyloliquefaciens FZB42. Seven-days inoculated plants were infested with the two clones of APA, different between them by the occurrence of the secondary endosymbiont Hamiltonella defensa. At the end of all experiments, it was highlighted that the aphid without the secondary endosymbiont seems to be negatively impacted by the PGPR. Contrary, the clone with the endosymbiont seems to be, in a first time, favoured by this Bacillus but this effect did not remain until the end of the experiment.

Platelets and Aspirin-Induced Asthma is the first book to be published that reflects research conducted on aspirin-induced asthma pathogenesis. It is examined through positions of neuroimmunoendocrine interactions in organism. The Melatonin hormone plays a key role, being the regulator and coordinator of complicated and interrelated biological processes. This new concept of aspirin-induced asthma pathogenesis suggests new methods for treatment of this disease by means of correcting the melatonin content in the patient's organism. Investigations into the mechanisms of aspirin-induced asthma

Phytohormones are known to  direct plant growth, in a coordinated fashion in association with the metabolism that supplies energy and the building blocks to generate the form that is recognized as a plant. Out of the chemicals recognized as hormones, attention has largely been focused on Auxins, Gibberellins, Cytokinins, Abscisic acid, Ethylene and more recently to Brassinosteroids. However, this book provides the recent information about a natural chemical, Salicylic Acid, that could be raised to the status as assigned to the above phytohormones because it has significant regulatory impact on important aspects of the plant life.  Salicylic acid (SA) was first discovered as a major component in the bark extracts from Salix (willow) which was used as an anti-inflammatory drug. However, SA is ubiquitous in plants, generating a significant impact on plant growth and development, photosynthesis, transpiration, ion uptake and their transport. Moreover, SA also induces specific changes in leaf anatomy and chloroplast structure. SA is recognized as an endogenous signal, mediating in plant defence, against pathogens.  In this book a total of 16 chapters have been included which provide a recent update on salicylic acid. This book is not an encyclopedia of reviews but includes a selected collection of newly written, integrated, illustrated reviews describing our knowledge on salicylic acid. The aim of this book is to tell about the salicylic acid involvement in plants, by the present time. The various chapters incorporate both theoretical and practical aspects which may serve as a baseline information for future research through which significant developments are possible. We are of the opinion that this book will be of immense importance to all those who have even the least interest in biological and agricultural sciences.

Carotenoids are uniquely functional polyene pigments that are ubiquitous in nature; aside from being responsible for the color of a wide variety of vegetables, interest has been focused on food carotenoids due to their likely health benefits. This Special Issue, “Carotenoids in Fresh and Processed Food: Between Biosynthesis and Degradation”, consists of five peer-reviewed papers that cover a numerous new insights on the chemistry of carotenoids together with some observations related to their protection from photodegradation. Moreover, other considerations about their biosynthesis and influencing parameters in fresh food are included.
