“…However, there is a growing consensus that the nutritional quality of protein is also of critical importance (Horie and Watanabe, 1983;Broadway and Duffey, 1988;Karowe and Martin, 1989;Felton, 1996). Protein quality is primarily the function of amino acid composition (Lehninger et al, 1993).…”

“…An imbalanced amino acid composition is associated with reduced growth (Briegel, 1985;Karowe and Martin, 1989). The quality of plant protein is highly variable among different species (Yeoh et al, 1992), changes in response to herbivory (Felton et al, 1992;Bi et al, 1994), and may be subject to both environmental and genetic variation (Felton, 1996). This variability of plant protein quality is likely to impose selective pressure shaping the behavioural and physiological adaptations of herbivores, but few studies have rigorously tested this possibility.…”

SUMMARY The present study evaluates the interactive effects of protein quality and the ratio of protein to digestible carbohydrate on herbivore performance,various aspects of nutritional homeostasis (feeding and post-ingestive regulation) and food choice. In the first experiment, final-instar caterpillars of generalist-feeding African cotton leafworm Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) were confined to one of 20 diets varying in protein:carbohydrate (P:C) ratio (35:7, 28:14, 21:21,14:28 and 7:35) and in the quality of dietary protein (0%, 20%, 50% and 80%replacement of casein-based protein mix with the low-quality plant protein,zein). Results indicated that the negative impact of low-quality protein on survival, development and growth was amplified as the P:C ratio of the diet fell. Consumption differences were the main underlying cause of this response. The effect of low protein quality was to reduce the efficiency of nitrogen utilization and to increase the conversion rate of ingested nutrient to lipid growth, irrespective of P:C ratio. In the second experiment, caterpillars were allowed to self-compose their preferred diet, selecting between one of four high-protein diets (all 35:7, but containing 0%, 20%, 50% or 80% zein) and one of four equal-P:C-ratio diets (21:21, again containing 0%, 20%, 50% or 80%zein). Caterpillars showed a compensatory increase in their self-selected P:C intake in response to the moderate decline in protein quality of the 35:7 food. No such response was demonstrated for the insects presented with 35:7 food with the lowest protein quality. The significance of these findings is discussed within the context of herbivore food selection.

“…Thus, the relationship between insects and their host plants are regulated via present compounds such as nitrogen compounds, carbohydrates, amino acids and many other compounds (Awmack and Leather, 2002). Developmental time of insects changes due to nutritional requirements that typically reflects in changes of food consumption and feeding behavior (Felton, 1996;Browne and Raubenheimer, 2003). It was observed that the net reproductive rate (R 0 ), the intrinsic rate of increase (r m ) and the finite rate of increase (λ) of C. chalcites decreased in the larvae fed on cultivar Calj.JN3.…”

Effects of six commercial tomato cultivars, Super Strain B, Super crystal, Hed rio grande, SUN 6108 f1, Rio grande UG and Cal.JN3 were determined on digestive physiology and life table parameters of Chrysodeixis chalcites (Esper). The highest values of consumed foods were determined in the larvae fed on Rio grande UG and Cal.JN3 while the lowest values were observed on SUN 6108 f1. Statistical difference was found in the pupal weight by the highest value on SUN 6108f1. The highest values of intrinsic rate of increase (r m ) and the net reproductive rate (R 0 ) were obtained on SUN 6108 f1 but the lowest values were obtained on Cal.JN3. Significant differences were also found in activities of digestive enzymes including specific proteases, α-amylase, glucosidases and TAG-lipase. Our findings showed that the highest and the lowest activities of specific proteases and TAG lipase were obtained on Rio grande UG and SUN 6108 f1, respectively. In addition, activities of the carbohydrases were the highest in the larvae fed on Cal.JN3. The demographical and physiological findings here revealed Cal.JN3 and Rio grande UG as the partially unsuitable cultivars for C. chalcites in comparison with other ones which may be recommended in integrated pest management. Keywords:Chrysodeixis chalcites, life table, digestive enzyme, tomato cultivar.Quality and quantity of host plants are described as presence of components affecting positively or negatively nutritional performance of herbivorous insects (Browne and Raubenheimer, 2003). These parameters depend on chemical compounds in host plants which are divided into four main groups including nitrogen-containing compounds, cyanogenic glycosides (glucosinolates), terpenoids and phenolics although some of them including alkaloids, phenolics, flavonoids and tannins are found occasionally in some families of plants (Schoonhoven et al., 1998). These chemicals, somehow defensive metabolites, are primarily toxic whereas others have anti-feedant and/or repellent properties leading to plant resistance against herbivorous insects. Host plant resistance occurs under three main mechanisms as antixenosis, antibiosis and tolerance by presence of secondary metabolites or morphological properties (Schoonhoven et al., 1998). Plants with antibiosis mechanisms may directly alleviate insect survival, size or weight, longevity and fecun-

“…An increase in CA activity and in the titer of juve nile hormones when stressed is common in insects (Chernysh, 1991;Hirashima et al, 1995;Gruntenko et al, 2000). For example, it results in an increase in con sumption of nutritionally poor food (Felton, 1996), changes in the activities of the digestive enzymes (Iva novic & Jankovic-Hladni, 1991) and induction of detoxi fying enzymes (Terriere & Yu, 1973). Thus it is now important to demonstrate what neurosecretions are pro duced by L1 NSN, and the rates of JH synthesis and/or the titers of JH in the haemolymph.…”

Abstract. The activity and number of protocerebral neurosecretory neurons ofthe dorsolateral group (L1, L2 and L2'), as well as the size of the corpora allata were investigated in 5th instar larvae of the gypsy moth (Lymantria dispar) from two populations (oak and locust-tree forests) fed one of two host-plants (oak is a suitable and locust-tree an unsuitable host-plant).The monitoring of activity related cytological parameters and the number of protocerebral dorsolateral neurosecretory neurons revealed that differently adapted populations respond to nutritive stress differently. The activity of the L1 neurosecretory neurons in the protocerebra of the caterpillars is low in those from the locust-tree forest regardless of host-plant quality. The L2 neurosecretory neurons in the oak population become active when they were fed the unsuitable host-plant whereas their activity was high in locusttree caterpillars regardless of the host-plant. A decrease in the number of neurosecretory neurons in a response to a novel food was noticed in both populations. The activity of the L2' neurosecretory neurons was similar in all caterpillars, but their number was increased in those from the locust-tree forest. The corpora allata of the locust-tree caterpillars were large whereas those of the oak forest caterpillars only increased in size when they were fed locust-tree leaves.It is obvious that nutritive stress results in neurosecretory reorganization and changes in the titre of hormones that modulate the morphogenetic programme.
