“…Joern and S. Mole, unpublished data). Egg production in several grasshopper species can be quite responsive to changes in dietary N as well (Smith and Northcott 1951;McCaery 1975). Likewise, switching females from high-to low-protein diets resulted in an immediate decrease in egg production and resorption of terminal oocytes (McCaery 1975); opposite results were obtained after switching females from low-to highprotein diets.…”

“…More needs can be satis®ed if nutritional resources are abundant compared with limiting situations. As a consequence, growth or reproduction will drop o or cease if the diet becomes inadequate (McCaery 1975;Bernays 1982), and survival (re¯ecting maintenance capabilities) varies with diet quality as well (Smith and Northcott 1951;Joern and Gaines 1990). While selecting food resources, grasshoppers simultaneously obtain protein and energy in addition to other nutrients, including water (Dadd 1985).…”

Key demographic traits in insect herbivores (survival, growth, and egg production) are often responsive to variation in diet quality, especially to dietary nitrogen (N) levels. Soluble carbohydrates may also be limiting. Using defined diets under controlled laboratory conditions, we examined survival, growth, and egg production in response to a range of diet qualities in adult females of a grass-feeding grasshopper Ageneotettix deorum (Scudder). Diets varied factorially within naturally occurring ranges of total N (1-7%) and carbohydrate (4-27%) levels. N concentrations significantly impacted weight gain, egg production rate, the elapsed time until the first egg pod, and the time between the first and second egg pod. These responses were typically quadratic in nature with a maximum response near 4-5% total N. The rate of pod production rather than number of eggs per pod best explained changes in reproductive rate. Dietary carbohydrate levels seldom exerted a significant impact on demographic parameters except when interacting with N on survival, egg weight, and the period between egg pods. Clearly, factors that alter the availability of quality diet, especially total N levels, can contribute to demographic responses in A. deorum.

Tropical tasar silkworm, Antheraea mylitta (Lepidoptera: Saturniidae) is a polyphagous silk producing forest silkworm of commercial importance in India. Forest dependent people rear its larvae on different forestry host plants twice or thrice in a year for small household income. Larvae of A. mylitta feeds on many forest tree species, but always show a great degree of selectivity as a function of its behavioural responses to physical structure and chemical features of the host plants. Cocoon crop of A. mylitta is influenced by heterogeneity of tasar food plants and climatic conditions of the habitat. The role of host plants, temperature, humidity, rainfall, photoperiod and climatic variables on the growth and development of insects have clearly been demonstrated. This article entails an in-depth analysis on ecological and nutritional aspects of A. mylitta, which may provide selective information to researcher and forest managers, who are particularly associated with livelihood improvement of the poor people in forested area through location specific forest insect industry. In nature, A. mylitta has opted forty-five forest tree species as primary, secondary and tertiary food plants (Srivastav and Thangavelu, 2005) and have built up sixty-four different forms of ecological populations called ecoraces (Rao et al., 2003). The polyphagous nature of the tasar silkworm is a boon for many rural tribal in central The knowledge regarding insect-host plant relationship has highlighted the food preference by insects with regard to its nutritional value. Long back, Hiratsuka (1920) carried out a comprehensive quantitative study on digestion and utilization of Bombyx mori on mulberry leaf. Thereafter, Evans and Goodliffe (1939) worked on utilization of food by insects. Earlier studies on utilization of food by insects were not clearly described because several indices were used to report more or less the same measurement in different names (Hopkins, 1912;Evans and Goodliffe, 1939; Crowell, 1941;Smith, 1959;Mathur, 1967;Saxena, 1969). Study of the effects of host plants on the biology of insects is important in understanding the host suitability under different environmental condition (Xue et al., 2009). First, Thangavelu (1992 emphasised the need for conservation of wild sericigenous insects in Himalayan states of India. He highlighted the importance of systematic research on various aspects of non-mulberry silks, because studies on the host plant interaction of sericigenous insects are necessary for better management and development of the sericulture industry (Sinha et al., 2000). Siddiqui et al. (2006) stressed that conservation of A. mylitta in different pockets of forest under different geographical and climatic area is necessary and some of the commercial ecoraces of A. mylitta viz., Raily, Modal, Bhandara, Sukinda, Daba and Andhra local are being maintained in different forest areas of central India; but it is lacking in Uttarakhand. As suggested by many sericulturists, the specific climatic and geographical pockets...

The direct approach to the study of the food requirements of insects is to rear them on artificial diets. Studies on insect growth and egg-laying rates on plant food raised in this way have been reported by Smith & Northcott (1951) (Melanoplus mexicanus mexicanus (Sauss.) have been raised successfully in this way (Bottger, 1942;Beck & Lilly, 1949).

The direct approach to the study of the food requirements of insects is to rear them on artificial diets. This has, however, proved difficult in the case of those normally feeding on living plants, although larvae of the European Corn Borer (Pyrausta nubilalis (Hb.)) have been raised successfully in this way (Bottger, 1942;Beck & Lilly, 1949). Changes in the food value of leaves may, nevertheless, be readily induced under controlled conditions by growing plants in sand or water culture. Studies on insect growth and egg-laying rates on plant food raised in this way have been reported by Smith & Northcott (1951) (Melanoplus mexicanus mexicanus (Sauss.) on wheat), Dahms (1947) (Blissus leucopterus (Say) on sorghum); Wittwer & Haseman (1945) (Heliothrips haemorrhoidalis (Bch.) on New Zealand spinach); Haseman (1946) (greenhouse whitefly (Trialeurodes vaporariorum (Westw.)) on petunia and tomato; Toxoptera on wheat); Creighton (1938) (Alabama on cotton); Barker & Tauber (1951) (Myzus persicae (Sulz.) on Tropaeolum); Allen & Selman (1955) (Phaedon cochleariae (F.) on watercress). Similar work has also been carried out with a mite (Tetranychus) by Garman & Kennedy (1949) and by Eodriguez (1952). There are also numerous relevant field observations of uncertain value (reviewed by Allen, 1954).Little is known concerning the response of leaf-eating caterpillars to the mineral nutrition of the food-plant, although Evans (1938) obtained indications that the carbohydrate and nitrogen content of the plant affected the rate of growth of Pieris brassicae (L.). He found that larvae fed on plants grown in the shade increased in weight more slowly and pupated later than those fed on plants grown in normal light. This slower rate of growth was probably related to the lower carbohydrate and nitrogen content of the plants grown in the shade.In the present work it was found that larvae of P. brassicae were well suited to the study of the effect on insect development of mineral deficiencies in plants, since they are not limited to one species of food-plant, and are easily reared and handled. Technique.In the first experiment, larvae of P. brassicae were fed on leaves of cauliflower grown in sand culture at two levels of nitrogen; in the second experiment the diets consisted of leaves of turnip grown in sand culture with complete nutrients and with deficiency of nitrogen, phosphorus or potassium, respectively; in the remainder of the experiments leaves of watercress grown in complete nutrient or in iron-deficient water culture solutions were used. Apart from the differences between culture solutions (described below) the mineral-deficient and normal plants were grown under similar conditions and, in any one experiment, the different groups of plants were of similar ages.
