“…The genotype CNPA 9211-31 presents antibiosis resistance to A. argillacea (Ferreira & Lara, 1999) and the genotype CNPA 9211-41 plant is not considered appropriate for its development (Santos, 2001). In the present study, these materials did not indirectly influence in the reproductive capacity of P. nigrispinus.…”

Host plants may influence indirectly biological characteristics of predators, on a positive or negative way, poiting out the importance of studies evaluating the effect of cultivars on the third trophic level. This study evaluates the biological aspects and predatory capacity of Podisus nigrispinus adults fed Alabama argillacea larvae reared on cotton genotypes. The predator was fed daily with fourth instar larvae reared on leaves of the following genotypes CNPA Precoce 1 (hirsute), CNPA 9211-31 (high gossypol level), CNPA 9211-41 (medium gossypol level) and GL2 GL3 (gossypol glandless). The pre-oviposition, oviposition and post-oviposition periods and the oviposition capacity of P. nigripinus were not affected when preyed on cotton leafworms reared on the listed cotton genotypes. Mean weight of predator females was higher (126.2 mg) when they fed on A. argillacea reared on GL2 GL3 cotton leaves, in comparison to the observed weight (96.

“…Ferreira and Lara (1999) reported larval survival, depending on the cotton cultivar, ranging from 58 to 76% at 27°C, whereas Santos and Boiça (2001) study has it highest survivorship on CNPA Précoce 1 (86.2%) and CNPA 9211-29 (85.7%) cotton leaves. The low survival rate of A, argillacea larvae is believed to be due to poor food quality (low quantities of water and nitrogen, high quantities of fiber and tannin content; Carvalho 1981) and other secondary chemistry, such as gossypol (Stipanovic et al 2008).…”

“…Therefore, larval stage duration, survival rate, as well as pupal weight were altered according to the cotton cultivar. Penna et al (1989), Ferreira and Lara (1999), and Santos and Boiça (2001), reported that cotton genotypes affect pupal weight, survival and development of A. argillacea larvae. Although parameters such as oviposition and reproduction were not evaluated in our study, the pupal weight is positively related with the formation of healthy adults and consequently increases the number of eggs and fertility (Creenberg et al 2001).…”

“…This information can be used in developing a much better pest control strategies. Studies have evaluated the eff'ects of host plants on the potential of A. argillacea population growth (Montandon et al 1986, Ferreira and Lara 1999, Santos and Boiça 2001 or quantified the impact of this pest on cotton production reduction (Mai'chini 1976). However, this information about A. argillacea feeding is incomplete, especially for cotton that produces colored fibers.…”

Quantitative analysis of the consumption and use by herbivore pest's of the host plant is a common tool used for studying the interaction between insects and plants. Our goals were to quantify cotton leafworm, A/a¿)ama argillacea (Hübner) (Lepidoptera: Noctuidae), larval consumption rate in three cotton, Qos.njpium hirsutum L., cultivars that produce colored cotton fibers, and the effects of the consumption rate on A. argillacea pupal weight in greenhouse conditions. Larvae consumed a maximum of 0.69-1.03 g of leaf tissue over a 24-h period in all cultivars tested. Total consumption by A. argillacea larvae was highest when fed with 'BRS 200' leaves (2.89 g) and the lowest when fed with leaves from 'BRS Safira' (2.26 g). The regression analysis showed significant relationships between the quantity of leaf tissue consumed and pupal weights for each cotton cultivar. A. argillacea larvae fed on BRS 200 demonstrated a longer developmental period (14.84 d) than larvae fed on 'BRS Rubi' leaves (11.62 d) or BRS Safira (11.14 d). We concluded that BRS Safira presents the best quality food source for A. argillacea, BRS 200 is the worst, and BRS Rubí is intermediate. The longer developmental times of A. argillacea on BRS 200 may allow longer windows of opportunity for the use of biological control agents to reduce the damage caused by this pest and also would complete less generations per phenological cycle of the cotton crop.

“…Baseando-se neste parâmetro poder-se-ia considerar que esses dois genótipos não são adequados ao desenvolvimento de A. argillacea por causarem alta mortalidade, comportando-se, portanto, como resistentes a A. argillacea. Ferreira et al(1999), avaliando a resistência de A. argillacea a alguns genótipos de algodoeiro, determinou maior percentual de mortalidade das lagartas que alimentaram-se do genótipo CNPA 9211-31, concluindo que este material apresenta resistência do tipo antibiose.…”

ABSTRACT-Eleven cotton genotypes were evaluated for resistance to A. argillacea, considering biological aspects of young and adult phases of this insect. The trials were conducted in climatic chambers at 25±1 o C under relative humidity of 70±10% and photophase of 12h. The first instar was significantly larger when A. argillacea fed on CNPA 94/139 and CNPA Precoce 1 genotypes. During the second instar, the cotton leafworm fed CNPA 94/139 genotype presented significantly shorter period. The variation interval for the third and fourth instars duration was, respectively, 1.8 to 2.1 and 1.9 to 2.2 days. The cotton leafworm fed CNPA Precoce 2 presented fifth instar duration of 4.9 days. The leafworms average weight at 5 days of age was lower when fed CNPA Precoce 1 genotype. The pre-pupal and pupal periods ranged from 1.0 to 1.9 and 7.8 to 8.7 days, respectively. The interval variation for the larval phase was 13.1 to 14.7 days. CNPA Precoce 1, CNPA Precoce 2, CNPA 9211-18 and CNPA 9211-21 genotypes promoted significantly higher duration larva-adult period. During the larval and larva to adult periods, the leafworms fed CNPA 9211-41 and CNPA 9211-31 genotypes leaves presented lower survival rates, 64.2 and 60.7; 62.1 and 58.6% respectively. A. argillacea females originated from leafworms fed CNPA Precoce 1 genotype showed shorter oviposition period and lower number of eggs laid. It was concluded that CNPA 9211-31, CNPA Precoce 1, CNPA Precoce 2 and CNPA 9211-41 genotypes showed antibiosis and/or feeding nonpreference resistance, while GL2 GL3 and CNPA 9211-29 were susceptible to cotton leafworm.KEY WORDS: Insecta, host plant resistance, cotton leafworm, biology.RESUMO -Avaliou-se a resistência de onze genótipos de algodoeiro a A. argillacea, considerando-se aspectos biológicos das fases jovem e adulta deste inseto.
