The chinch bug, Blissus leucopterus leucopterus (Say) (Heteroptera: Blissidae), is the most important insect pest of pearl millet (Pennisetum glaucum L. R. Br.) production in the southeastern and central United States. Chinch bug feeding causes stunting and leaf sheath necrosis of the young seedlings and loss of crop stand in severe infestations. Sixteen germplasm entries (including hybrids and inbreds) of pearl millet were screened for chinch bug resistance on 2 planting dates. ‘Dove’ proso millet (Panicum miliaceum L.) was interplanted in 2-row strips among experimental plots to attract adult chinch bugs and establish initial chinch bug infestations. Use of a proso millet trap crop strip was effective in establishing chinch bug infestations for screening of pearl millet for chinch bug resistance in the field. Weekly samplings were begun when plants were at the 5-leaf stage. Significant differences in adult and nymph numbers, stunting and necrosis ratings, percent tiller loss, crop stand loss, and chlorophyll content were recorded for the 16 pearl millet germplasm entries. Combining all injury evaluation parameters (i.e., stunting and necrosis ratings, percent tiller loss, and crop stand loss), we identified that ‘TifGrain 102’ had a moderate level of chinch bug resistances e data demonstrated that, millet would aeh resistance. Entries 637 (i.e., 59668A × NM-5B), 639 (59668M × 9Rm/4Rm), 648 (i.e., 02GH973 × Tift 454), and 653 (i.e., NM-5A1 × NM-7R1R5) were the most resistant; whereas, entries 640 (i.e., Tift 99B), 641 (i.e., Tift 454), and 644 (i.e., 02F 289-1) were the most susceptible to chinch bug feeding. The study showed the combination of nondestructive visual ratings (i.e., stunting and necrosis ratings, tiller loss, and stand loss) and chlorophyll content could be used for evaluating chinch bug resistance in pearl millet.

The New Zealand endemic wheat bug, Nysius huttoni (Hemiptera: Lygaeidae), is a pest of brassica seedlings. However, it has a wide host range comprising almost all cultivated brassicas, cereals and many other cultivated crops, as well as weeds. The brassica alyssum (Lobularia maritima) is a potential trap crop of N. huttoni, having the potential to keep the bugs away from seedlings. Laboratory no-choice and choice tests evaluated the relative preference of N. huttoni for two major growth stages of alyssum – vegetative and flowering. In both bioassays, N. huttoni adults settled significantly more promptly on the flowering than on the vegetative stage. The same preference was evident for adult numbers settling. Survival was higher on the flowering (38%) than on the vegetative stage (28%), although this was not significant. The implications of these findings are important in the design of trap cropping protocols for N. huttoni management. Flowering alyssum in brassica fields can also potentially improve pest biological control and provide other ecosystem services that can contribute to mitigating diminished ecosystem functions in agriculture.

A 3-yr study evaluated tobacco as a trap crop for the tobacco budworm, Heliothis virescens (F.), in cotton. Small plot experiments were conducted on an experimental farm at Mississippi State University in Starkville, MS, in 1996 and on a commercial farm in Aliceville, AL, in 1997 to determine the ability of small strips of tobacco to trap H. virescens in cotton field plots. In the 1996 experiment, tobacco budworms eggs were significantly higher on tobacco than on cotton from 7 June through 19 June and from 10 July through 22 July. In 1997, H. virescens eggs were significantly higher on tobacco than on cotton for every sampling date throughout the growing season. The conclusion derived from these small plot experiments was that H. virescens females preferred tobacco over cotton as an ovipositional site. Therefore, in 1998, a large-scale field experiment was conducted to determine the effectiveness of tobacco as a trap crop for H. virescens in commercial cotton fields in Funston, GA. In this experiment, the number of H. virescens eggs was significantly lower in cotton fields with tobacco trap crops compared to control cotton fields without tobacco trap crops on 2 and 9 July. Also, economic threshold for H. virescens was not reached in these cotton fields with tobacco trap crops. In contrast, the economic threshold for this pest was met in cotton fields without tobacco trap crops on two dates during the growing season. For each year of the study, percentage total real mortality (rx) for eggs and larvae of H. virescens on tobacco was very high, ranging from 91.4–99.9%. Larval mortality was attributed in part to parasitization by Toxoneuron nigriceps (formerly Cardiochiles nigriceps) Viereck and Campoletis sonorensis Cameron and an infection by an ascovirus of H. virescens. Thus, tobacco served as a trap crop and sink for H. virescens in cotton in this study.

Experiments were performed in pot and field conditions to evaluate effects of non-host crops on Orobanche seed bank. The two sites chosen for the study were located in highly Orobanche infested areas of Nawalparasi district, an inner Terai region of central Nepal. Pot and field experiments were conducted in the soil naturally infested with Orobanche seeds. Altogether, 21 different non-host crop species were tested in the study. Orobanche seed density in soil samples collected from pot/plot before planting and after harvest of each crop species was recorded. Data of pre-plant and postharvest were compared in order to assess the effects of the test crops on Orobanche seed density. On the basis of degree of effects on the Orobanche seed bank, the investigated crop species could be classified in to three categories: (a) non-potential trap crop: garlic, chilli, coriander, carrot, buckwheat, sunflower, french bean, pea, egg plant, potato, fenugreek, wheat and faba bean; (b) moderately potential trap crop: barley, onion, chickpea and maize; and (c) highly potential trap crops: radish, lentil, linseed, fennel and cumin.DOI: http://dx.doi.org/10.3126/eco.v19i0.9851EcoprintAn International Journal of EcologyVol. 19, 2012Page: 31-38Uploaded date: 2/14/2014
