“…These characteristics caused high mortality in the larval and pupal phases and contributed to this genotype's classification as highly resistant (group V) in hierarchical grouping. Active chemical compounds that are metabolized by the plant become physiological toxins that cause antibiosis, or deterrent substances that prevent insects from feeding and reduce survival rates (Eigenbrode et al ., 1990; Chagas Filho et al ., 2010).…”

Chickpeas (Cicer arietinum L.) belong to the Fabaceae family and are one of the most grown crops in the world and an important source of protein for humans. Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) is a polyphagous pest that causes significant crop damage. The objective of this study was to examine antibiosis to S. frugiperda in chickpea genotypes. The following genotypes were studied: Jamu 96 and Blanco Sinaloa 92 (Mexico); Nacional 29 (Cuba); BG 1392 (Spain), and BRS Kalifa, BRS Cristalino, BRS Toro, Nacional 27, 004UP, 003UP, BRS Cícero, and BRS Aleppo (Brazil). The chickpea genotypes influenced the biological parameters of S. frugiperda, of which larval period, larval weight, and pupal period were most affected. Nacional 29 caused high mortality in the larval and pupal stages of S. frugiperda. The larvae on BRS Aleppo had the longest larval stage, lowest weight, and longest pupal stage. The genotypes Nacional 29, Nacional 27, and BRS Cícero showed antibiosis resistance to S. frugiperda. These genotypes could be used as a source of resistance to S. frugiperda in conjunction with other methods of pest control in integrated pest management programs for chickpea crops. These resistant genotypes could also be used as donor sources in breeding programs for insect resistance.

“…Plants were manually watered, and forty females of T. pretiosum were released inside. This number was chosen because each P. xylostella female lays an average of 15 eggs per day (CHAGAS FILHO et al, 2010) while each T. pretiosum female parasitizes 10 eggs per day on average (PASTORI et al, 2007;PEREIRA et al, 2007). Parasitoids were in contact with eggs for 24 hours and after this period, cages were disassembled and the plants were taken to the laboratory for evaluation.…”

The damage caused by the diamondback moth is a limiting factor in the production of brassicaceous plants worldwide and biological control by an egg parasitoid may be an effective way to control this pest. Thus, understanding oviposition preferences of pests and parasitoids in crop plants can be a key factor in optimizing biological control programs. The present study was aimed at determining the oviposition preference of Plutella xylostella and Trichogramma pretiosum in collard greens. Bioassays consisted of collard plants in cages and P. xylostella adults released inside to lay eggs on the leaves. After 24 hours, the adults were removed and T. pretiosum females released. In another experiment, cardboard strips containing P. xylostella eggs were offered to T. pretiosum released in cages with a collard greens plant inside and replaced every 2 hours for 24 hours. The results showed that P. xylostella has a preference for laying eggs on the leaves of the middle region of the plant, on the upper part of the adaxial surface. For T. pretiosum, no preference was observed, but mean parasitism rates were highest on the upper region of the adaxial surface, where most of the eggs were found. In the second experiment, the highest mean parasitism rates by T. pretiosum were observed at temperatures ranging from 25.9 to 37.4 °C and relative humidity between 42 and 78% in the photophase. No parasitism occurred in scotophase, indicating that field releases should be performed preferably in the early hours of the morning.

Wax Removal and Diamondback Moth Performance in Collards Cultivars

The diamondback moth Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae) is an herbivorous specialist on Brassicaceae species. Brassicas spp. plants developed a range of defenses (chemical, physical, and morphological) to prevent herbivores attack. In this study, we reported the antixenotic and antibiotic effects of outermost layer of two species of epicuticular wax of Brassicaceae, Brassica oleracea L. var. "Santo Antônio," and Hybrid Kope F1 100MX, on larvae and adult of P. xylostella. In the choice experiment, P. xylostella adults showed an oviposition preference for collard cultivars Santo Antônio (control) and Hybrid Kope F1 100MX with wax removal. In the no-choice experiment, oviposition was 6.4 times higher in the Hybrid Kope F1 100MX with wax removal than without wax removal. There were significant differences among larvae feeding on leaf disks of Hybrid Kope F1 100MX in the treatments with (65.3 mg) and without wax removal (23.5 mg). The net reproduction rate (R ), and intrinsic (rm) and finite rates of increase (λ) of P. xylostella in the cv. Santo Antônio were bigger in the treatment without wax removal (R = 50.4, rm = 0.23 and λ = 1.26) than treatment with wax removal (R = 28.5, rm = 0.20 and λ = 1.22). However, only the R value was affected by mechanical wax removal in the Hybrid Kope F1 100MX (with wax removal R = 43.3 and without wax removal R = 30.8). In conclusion, the results indicate that collard's wax is important to accessibility and development of P. xylostella, and its removal changes the resistance of collard's varieties to P. xylostella.
