“…It also has been demonstrated that addition of protein to diets containing o~-tomatine increases the growth rates of L. decemlineata larvae compared to the growth rates of larvae fed a similar diet containing ot-tomatine but without additional protein (Hare, 1987). Both the trichome-and lamellar-based resistance of PI 134417 can be reduced dramatically by increasing the rate and/or frequency of fertilizer applications (Barbour et al, 1990; see also Dodds, 1987 andJanssen andSmilowitz, 1986a,b for similar work in tomato and potato, respectively).…”

The role of the steroidal glycoalkaloid α-tomatine in the hostplant resistance of tomato to the Colorado potato beetle,Leptinotarsa decemlineata (Say) was examined in short- (24 hr; using first- and fourth-instar larvae) and long-term (first-instar larvae reared through the prepupal stage) feeding experiments. Consumption rate, growth rate, efficiency of conversion of ingested food to body mass, and survival were compared forL. decemlineata provided foliage from susceptible (Lycopersicon esculetum Mill. cv. Walter), resistant (L. hirsutum f.Glabratum C.H. Mull accession PI 134417), and F1 hybrid plants. Values obtained for dietetic indices were regressed against corresponding values for α-tomatine content of foliage provided to larvae. Differences in dietetic indices could not be attributed to variation in foliar α-tomatine content despite a long-standing literature showing theex planta α-tomatine inhibits feeding and growth byL. decemlineata.

“…However, in the high-yielding areas, such as the Yangtze Delta area, the usage of nitrogenous fertilizer could be 270-300 kg per ha and here the recovery efficiency for N is only about 20 % (Peng et al 2002;Li and Tang 2006). Heavy applications of nitrogenous fertilizer may not affect insect biology directly but bring about changes in host plant morphology, biochemistry, and physiology, which could improve the plant's nutritional condition for herbivores and reduce host resistance to them (Barbour et al 1991). Thus, the excessive use of nitrogenous fertilizers creates favorable food conditions for rice planthoppers.…”

Rice Planthoppers

Historical developments of rice planthopper problems in China, as well as research efforts on these problems, in the past half century are reviewed. Compared with tropical rice ecosystems, population development patterns of rice planthoppers in Chinese rice ecosystems are characterized as multiple planthopper pest species, complex immigration sources, high growth rate, and high outbreak frequency. Historical data on rice planthopper problems reveal that frequent outbreaks of rice planthopper problems in China are mainly the result of vulnerable rice ecosystems associated with susceptible host plant varieties and weak natural regulation in intensive rice ecosystems and subject to variable immigration levels and meteorological conditions. To feed an increasing population in China given the limited arable land available, sustainable intensive rice ecosystems with high natural regulation of planthopper populations need to be established by enhancing the resilience of the system to rice planthoppers, developing international and regional collaboration, and reforming decision-making systems for rice planthopper management.Keywords Brown planthopper · White-backed planthopper · Small brown planthopper · Intensified ecosystems · Sustainable management World population started to increase quickly after the 2nd world war and reached 3 billion in 1960 and 7 billion before the end of 2011, which indicated that the world population has been increasing with a speed of 1 billion per 12-14 years and has more than doubled during the past half century. In China, the population in 1960 was about 0.66 billion, but has reached more than 1.34 billion now, which means the population has doubled in this half century, even where the one child per family policy has been implemented since the 1980s. At the same time, the total arable land in China, which was 136 million ha in early 1950s, is now only around 120 million ha (MOA 2012). How to feed ourselves given an increasing population and a limited and declining area of arable land is a major challenge for the future.

“…Host plant rearing was regulated so as to limit the variation in plant phenological effects (e.g. changes in fertiliser regime [Barbour et al, 1991] and differences in leaf age [e.g. Noldus et al, 1986b].…”
