“…This research will help to develop a fundamental understanding of the biochemical basis that contributes to plant resistance to insects and also to compare the genotypes for resistance and susceptible ones to MYMV resistance. The results were in conformity with the findings of earlier workers viz., Raghuraman et al (2004); Balakrishnan (2006) in field bean; Murugan et al (2007) in tomato and Taggar et al (2014) in urdbean.…”

Mungbean yellow mosaic virus (MYMV) is a whitefly-transmitted major destructive virus affecting urdbean productivity in India. The objective of this research was to identify urdbean genotypes resistant against MYMV based on the phenotypic reaction and genotypic analysis. A total 48 urdbean genotypes were evaluated for resistance to MYMV by visual scoring of symptoms in the field under natural conditions. Disease severity was assessed using 0-9 rating scale, according to the mean disease score, the urdbean genotypes were categorized into five groups resistant (R, 14 genotypes), moderately resistant (MR, 4 genotypes), moderately susceptible (MS, 10 genotypes), susceptible (S, 18 genotypes) and highly susceptible (HS, 2 genotypes). These results were confirmed through genotyping based on MYMV-resistance tagged molecular markers CEDG180, ISSR8111357 and YMV1 FR. In addition, biochemical analysis was carried out in the genotypes of each category (R-HS). Results showed that MYMV resistance was significantly and positively correlated with the phytic acid and total phenol contents, whereas negative correlation was observed with total sugars in susceptible genotypes. The new identified genotypes (resistant sources) can be utilized in the urdbean breeding programme for improving resistance to MYMV.

“…Nitrogen is a key factor for the growth and reproduction of insects (Simpson et al 1995;Joern and Behmer 1997;Blackmer and Byrne 1999;Bi et al 2001Bi et al , 2003Messina et al 2002;Cui et al 2012). Insect infestations induce changes in the nutritional value of plants and provoke the redistribution of nutrients in source-sink sites, with significant effects on the future performance of phytophagous insects (Kessler and Baldwin 2001;Mayer et al 2002;Messina et al 2002;Murugan and Dhandapani 2007;Cui et al 2012). However, the outcomes of insect-plant interactions are variable and species specific (Walling 2000;Mayer et al 2002;Ohgushi 2005).…”

Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) uses a flush‐and‐lacerate feeding strategy producing necrotic rings (NR) at feeding sites in tomato plants. The aim was to investigate the variation in the concentrations of amino acids (aa) and sugars at feeding sites, and its effect on this mirid's life‐history traits and behaviour. The concentration of nutrients was measured in different parts of stems damaged by N. tenuis and mechanically using liquid chromatography. aa concentrations increased below NR; around and above NR, the concentrations of essential and non‐essential aa declined. The concentration of glucose was lower around NR and below. The change in the distribution of aa was similar in NR and mechanically damaged stems, whereas there were no differences in sugar contents. Development time and nymphal mortality were measured on fresh leaflets, leaflets with NR and leaflets plus Ephestia kuehniella Zeller (Lepidoptera: Pyralidae). Without prey, development took longer on NR than on fresh leaflets. Development was quicker and mortality lower on leaflets plus moth eggs. Finally, behavioural events were recorded in fifth‐instar nymphs of N. tenuis in: (i) double‐choice experiments (DCE) using leaflets with and without NR; (ii) DCE using leaflets exposed and non‐previously exposed to nymphs and (iii) fresh tomato leaflets plus Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) nymphs. In (i), feeding events lasted longer at NR sites; in (ii), the behaviour of the nymphs on previously exposed leaflets was not significantly different from fresh leaflets; and in (iii), most of the time was dedicated to prey feeding. The overall results indicate that N. tenuis do not take advantage of the inhibited translocation of nutrients in the phloem. The poorer performance of nymphs on leaflets from plants previously exposed to N. tenuis might be due to a general decrease in the concentration of nutrients or to the activation of plant defences.

“…Available information on induced resistance to arthropods mostly refers to chewing herbivores, which usually cause extensive leaf damage to infested plants. Little is known to date about plant responses to whiteflies induced after previous attacks by arthropods or by other inducer organisms Inbar et al 1999;Murugan and Dhandapani 2007).

Cover illustration: Whitefly -USDA-ARS, Scott BauerPrinted on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) This book is dedicated to Dr. Jacquelyn (Jackie) L. Blackmer , a coauthor of Chapter 5 and a renowned entomologist in the field of insect behavior, insect-plant interactions, and insect dispersal and migration. During postdoctoral work at The University of Arizona and her most recent tenure with the United States Department of Agriculture, Agricultural Research Service in Arizona she made numerous advances in understanding the behavior, physiology and ecology of Bemisia tabaci. Dr. Blackmer conducted some of the first and still the most comprehensive studies on the migratory and short-range flight behavior of Bemisia tabaci including the role of environment, physiology, morphology, life history and host quality. She advanced our understanding of host quality factors in whitefly life history, developed an artificial diet system, and examined the flight behavior of whitefly parasitoids. She was a tireless, innovative and inspirational researcher as well as being a generous collaborator, colleague and friend to all with whom she worked. Her significant contributions to entomology will be long remembered and will continue to inspire advances in whitefly biology, ecology and management.v
