“…To prevent or at least delay resistance development in maize borers, a high expression of the Bt toxin combined with a refuge approach in which non-Bt plants are sown in the proximity of Bt plants, either in different fields or by mixing seeds, has been proposed and implemented in some areas. Because the antixenosis experiment was conducted under no-choice and choice conditions with different ratios of transgenic vs. non-transgenic varieties, there was no indication that the transgenesis had modified short range cues, e.g., plant volatiles, which were reported to influence the oviposition of S. nonagrioides (Konstantopoulou et al, 2002). Preference for Bt plants would require an increase in the number of refuge plants to counter an increased selection pressure, whereas preference for non-Bt plants would have the opposite effect (Hellmich et al, 1999).…”

“…Preference for ovipositing on non-Bt maize plants could delay the development of resistance to Bt in maize when non-Bt and Bt plants are mixed in close proximity because a greater proportion of the descendants would continue to be susceptible. Among maize borers, occurrence of antixenosis in Bt varieties has been studied in Ostrinia nubilalis H€ ubner (Orr & Landis, 1997;Hellmich et al, 1999), but not in S. nonagrioides, although some plant chemical stimuli have been cited as deterrents or repellents for oviposition (Konstantopoulou et al, 2002). Antixenosis has been reported to occur in some insects and non-maize Bt crops (Bernal & S etamou, 2003;Men et al, 2005), but not in others (Van den Berg & Van Wyk, 2007;Obonyo et al, 2008;Lima & Torres, 2011).…”

Sesamia nonagrioides Lef ebvre (Lepidoptera: Noctuidae) is a key pest of maize [Zea mays L. (Poaceae)] and a main target of Bt maize in the Mediterranean area. To choose the most suitable non-Bt refuge strategy for preventing or delaying resistance development in this maize borer, we examined its biology and behaviour. No antixenotic effects were found on numbers of eggs and egg batches per plant in choice (Bt vs. non-Bt plants) and no-choice assays. However, a greater ratio of young larvae dispersed from Bt than from non-Bt plants. In addition, larvae that hatched on Bt plants tended to disperse more than those that hatched on non-Bt plants, particularly during young growth stages. Many adults, especially females, could fly at least up to 400 m, as was found in a dispersal study with rubidium-marked adults. The stimulation of larval dispersal by the Bt trait and the dispersal capacity of adults might compromise the efficacy of seed mixtures as an insecticide resistance management strategy.

“…Phytophagous insects often demonstrate preferences for particular plant species, cultivars, or crop stage in response to different cues, a behavior that can be exploited to manage insect pests through the use of trap crops (Hokkanen, 1991; Shelton & Nault, 2004). Host‐plant recognition and selection in Lepidoptera is primarily a function of the ovipositing female (Konstantopoulou et al., 2002), and, as newly emerged larvae are often limited in their dispersal abilities, oviposition is particularly crucial because it determines survival of their progeny (Renwick, 1989). A majority of these insects are, therefore, able to discriminate between plants that are acceptable for oviposition and feeding and those that are not (Otter & Kahoro, 1983; Rebe et al., 2004).…”

Evaluation of Napier grass (Pennisetum purpureum) varieties for use as trap plants for the management of African stemborer (Busseola fusca) in a push–pull strategy

We evaluated eight Napier grass [Pennisetum purpureum Schumach (Poaceae)] varieties, used in various parts of eastern Africa as fodder, for their potential role as trap plants in the management of the African stemborer, Busseola fusca Füller (Lepidoptera: Noctuidae) through a push–pull strategy. Oviposition preference, larval orientation, settling, arrest and dispersal, feeding, mortality and survival, and development were determined for each of these varieties under laboratory and screen house conditions. Two‐choice tests showed that only two of the varieties tested (cv. Bana and cv. Uganda Hairless) were preferentially chosen by gravid female moths for oviposition over a susceptible maize variety, cv. Western Hybrid 502. Larval preference was, however, highly variable. Larval feeding by first instars on the maize leaves was more intense and significantly more than on leaves of all the Napier grass varieties evaluated. Food consumed and amounts assimilated by the third instars over a 24‐h period were not different among larvae fed on stems of maize and those fed on stems of the various Napier grass varieties. Larval survival was significantly lower on all the Napier grass varieties (below 3%) than on maize (about 44%). Similarly, larval development was about 2–3 weeks longer on majority of the Napier grass varieties. It was concluded that cv. Bana had potential for use as a trap plant in the management of B. fusca because it was more preferred by the moths for oviposition, equally preferred as maize by the larvae for orientation, settling, and arrest, and allowed minimal survival of the larvae. It can thus be used with such ‘push’ plants as Desmodium spp. (Fabaceae) in a ‘push–pull’ strategy, but the effectiveness of such a strategy would strictly depend on proper establishment and management of these companion plants.

“…In an ecological aspect they are much safer than the synthetic pesticides. Nevertheless the natural plant products such as essential oils (Abd-El-Aziz, 2001;Upadhyay & Jaiswal, 2007) and bio-organic compounds (Konstantopoulou et. al., 2002) are safer and at same time toxic to phytophagous insects.…”

The possibilities for increasing the productivity and control of the pea weevil (Bruchus pisorum L.) in field pea (Pisum sativum L.) organic cultivation by the use of following bioproducts NeemAzal T/S and Pyrethrum FS-EC (insecticides), applied individually and in combination with Polyversum (growth regulator and fungicide) and Biofa (foliar fertilizer), as well as to evaluate the stability of the used mixtures were studied. Synthetic products Nurelle D and Flordimex 420 (alone and in combination) were used as a standard. The products were applied once (at budding stage) or twice (at budding and flowering stages). The results showed that forage pea productivity was influenced positively by the application of all organic products. The plants treated with the organic combinations formed an average yield of 3190.2 kg/ha, which was only 4.7% lower than that for the synthetic combination of Flordimex+Nurelle D. The highest yield was produced under application of two mixtures: Biofa+Pyrethrum and Polyversum+Pyrethrum at budding and flowering stages (22.0 and 21.8% above untreated control, respectively). These combinations were also distinguished for their most pronounced protective effect against the attack of the pea weevil and decrease in its numbers of 37.0 and 38.5%, respectively. Pyrethrum was distinguished for a lower degree of damaged seeds and a toxic effect against the pea weevil in comparison with NeemAzal. Technologically the most valuable variant, which united high stability, productivity and protection against pea weevil, was the combination of Biofa+Pyrethrum applied twice. Further investigations are indispensible to expand the range of products (bioinsectides, biofertilizers and growth regulators), which provides good insect control and high productivity in pea organic farming conditions. Additional key words: organic products; productivity; pea weevil control; stability.
