“…Mineral balance, which encompasses both ratios and levels, is important to plant biochemical function. Either deficient or excessive levels of certain plant nutrients can slow the production of more complex plant chemicals, potentially leading to the accumulation of simpler metabolic building blocks, such as free amino acids and sugars, which can provide an enriched diet for insect herbivores (Waldbauer, 1968) and/or stimulate oviposition or feeding (Augustine et al, 1964 ). In this manner, mineral imbalance may increase crop susceptibility to pests.…”

Soil-Management History and the Role of Plant Mineral Balance as a Determinant of Maize Susceptibility to the European Corn Borer

Proponents of organic fanning have long suggested that their methods produce "healthy" crops that are less susceptible to insects and diseases. Experimental comparisons of European corn borer (ECB) egg-laying response to maize plants grown in a greenhouse in soil collected from either organically or conventionally managed farms provided evidence consistent with these assertions. In each of three paired comparisons, higher egg-laying occurred on plants in conventional soil. Subsequent studies suggested that differences in ECB ovipositional preference were related to plant-mineral balance; a three-mineral quadratic model showed strong predictive power for ECB oviposition. A role for plant minerals was also suggested in a study of paired maize fields with high and low ECB populations compared at three different geographic locations. Significant differences in leaf-mineral profiles between fields were measured that were consistent across locations.Based on these cumulative findings, it is hypothesized that: (I) maize plants with an optimal mineral balance show lower susceptibility to insect pests, (2) detennining the effects of minerals on susceptibility must include consideration of both ratios and absolute levels, and (3) a more resistant physiological state is more likely in organically managed soils because of the inherent greater capacity of these soils to buffer availability of minerals to plants.

“…Previous studies have shown that it is possible to divert insect pests from soybean crop by growing an attractive trap in a smaller area for example leaf bean beetles, Cerotoma trifurcate, (Pedigo, 1989), Mexican bean beetles, Eplachna varivestis, (Augustine et al, 1964;Rust, 1977;Mcpherson, 1983), stink bugs, Nezara viridula, (McPherson and Newsom, 1984;Kobayshi and Cosenza, 1987), and scarabaeid beetles, Anomela cupripes and A. expansa, (Talekar and Nurdin, 1991). However, none of these studies have used a transgenic crop to divert insect pests.…”

The Potential ofBtCorn as a Trap Crop for the Control of Corn Earworm,Helicoverpa zeaBoddie, in Soybean

Corn and soybean are two important crops in the Delmarva (Delaware, Maryland and Virginia) peninsula region. Both crops are attacked by corn earworm (CEW), Helicoverpa zea (Boddie). The larvae cause significant ear damage to corn serving as a primary nursery for CEW populations which shift to soybean later in the season. In soybean, CEW larvae cause serious yield losses if not controlled by insecticides. Many farmers in the Delmarva region have been increasing the acreage they grow with genetically engineered corn hybrids that contain insecticidal proteins expressed by the genes of Bacillus thurngiensis sub sp. kurstaki (Bt) as an alternative to the application of chemical insecticides. A study was conducted to investigate the use of Bt corn as a trap crop for the management of CEW in soybean. Bt corn was planted as a trap crop in a ten percent of the area of soybean as a peripheral trap, trap Downloaded by [University of Chicago Library] at 23:36 18 November 2014in the middle and trap in the intermittent rows in soybean. CEW moths were attracted and observed on the newly formed silks of the ears of Bt corn in all types of traps including peripheral trap, trap in the middle and trap in the intermittents rows planted in soybean. CEW eggs were also observed on the silk of transgenic corn. The moths, eggs and larvae (CEW) were hardly observed in soybean grown as a main crop. Clearly, we were able to divert the CEW adults on Bt corn from soybean. The number of CEW eggs was significantly higher in the peripheral trap and trap in the intermittent rows compared with trap in the middle of the plots, suggesting that Bt corn planted as a peripheral trap crop could be more practicable and effective for the farmers in reducing the CEW damage in soybean.

No-choice feeding trials and automatic feeding detector studies were used in a quantitative analysis of the feeding behaviour of adult Mexican bean beetles on their host-plant. Different chemical stimuli and physiological factors gave clearly distinguishable patterns in the feeding process. Compared to controls: age had no marked effect; starvation synchronised and reduced the time of initiating feeding, increased consumption rates, increased feeding duration, but did not alter the number of meals; sucrose increased consumption rates over the same feeding duration as controls, and reduced the number of meals; phenolic compounds decreased consumption rates, feeding durations and number of meals. The methodology produces quantitative indices of specific feeding behaviours from the measurement of cumulative consumption/time data, while being sufficiently rapid for screening plant materials and chemicals. The methods are considered generally applicable to laboratory bioassays with phytophagous insects, and are being used to generate a predictive model for the Mexican bean beetle.
