“…Previous studies have also shown that many crop plants attract soybean insect pests and have the potential to be used as trap crops for the management of soybean insect pests (Talekar and Nurdin, 1991;Kobayashi and Cosena, 1987;Javaid and Joshi, 1995). In most of these studies the insect pests were attracted to a particular trap crop planted in a small area near the main crop and then controlled by the application of insecticide.…”

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.

“…This "optimal bad motherhood" hypothesis [13] appears for example when the potentially most suitable plant host for larvae is unsuitable for adult fitness and thus unattractive to mothers. Oligophagy increases the likelihood that the same plant species is best for the fitness of adults and larvae, so that oligophagous insects are less likely to be "optimal bad mothers" than polyphagous ones [14,15].Knowledge about insect host selection and preferences can be used to develop integrated pest management (IPM) strategies where the crop to be protected from a pest can be cultivated in combination with a far more attractive host plant used as a trap crop [16,17]. The trap crop diverts the pest from the main crop, which decreases economic damage.…”

The development of integrated pest management strategies becomes more and more pressing in view of potential harmful effects of synthetic pesticides on the environment and human health. A promising alternative strategy against Delia radicum is the use of trap crops. Chinese cabbage (Brassica rapa subsp. pekinensis and subsp. chinensis) is a highly sensitive Brassicaceae species previously identified as a good candidate to attract the cabbage root fly away from other crops. Here, we carried out multi-choice experiments both in the laboratory and in field conditions to measure the oviposition susceptibilities of different subspecies and cultivars of Chinese cabbages as compared to a broccoli reference. We found large differences among subspecies and cultivars of the Chinese cabbage, which received three to eleven times more eggs than the broccoli reference in field conditions. In laboratory conditions, the chinensis subspecies did not receive more eggs than the broccoli reference. We conclude that D. radicum largely prefers to lay eggs on the pekinensis subspecies of Chinese cabbage compared to the chinensis subspecies or broccoli. Some pekinensis cultivars, which received over ten times more eggs than broccoli in the field, appear especially promising candidates to further develop trap crop strategies against the cabbage root fly.Insects 2020, 11, 127 2 of 12 or to lay eggs on unsuitable ones, resulting in poor larval development [12]. This "optimal bad motherhood" hypothesis [13] appears for example when the potentially most suitable plant host for larvae is unsuitable for adult fitness and thus unattractive to mothers. Oligophagy increases the likelihood that the same plant species is best for the fitness of adults and larvae, so that oligophagous insects are less likely to be "optimal bad mothers" than polyphagous ones [14,15].Knowledge about insect host selection and preferences can be used to develop integrated pest management (IPM) strategies where the crop to be protected from a pest can be cultivated in combination with a far more attractive host plant used as a trap crop [16,17]. The trap crop diverts the pest from the main crop, which decreases economic damage. Moreover, if the trap crop is unsuitable for larvae (dead-end trap cropping), bad mother choice can be exploited to reduce the local population of the pest [18], limiting future crop damage. Numerous studies have revealed which plant hosts are preferred by major phytophagous insect pests and which are less appropriate for their larvae, with potential use in trap crop strategies [19][20][21]. However, preferences of insect pests have often been studied at the supraspecific or specific taxonomic levels while the wide infraspecific diversity created by plant breeding and varietal creation remains largely unexplored. This lack of information comes from the fact that conventional plant protection strategies based on pesticides do not require an extensive knowledge of plant susceptibility to insect pests and accordingly this trait is rarely considered i...

“…This modality was the primary focus of the two previous reviews (Javaid & Joshi, 1995). One of the most widely cited examples of successful conventional trap cropping, which served as a major contributor to the development of IPM in the central valley of California in the 1960s, is the use of alfalfa as a trap crop for lygus bugs in cotton (Godfrey & Leigh, 1994).…”
