Repelência de óleos essenciais e vegetais sobre pulgão-preto Aphis craccivora Koch na cultura do feijão-fava (Phaseolus lunatus L.)

A busca de bioinseticidas vegetais tem se intensificado, visto que os inseticidas naturais não são persistentes e degradam com maior velocidade que os sintéticos sem deixar resíduos nos alimentos ou no meio-ambiente. Objetivou-se com este trabalho avaliar a ação repelente de óleos essências e vegetais em pulgão-preto (Aphis craccivora Koch) em cultivares de feijão-fava (Phaseolus lunatus L.). Para realização do experimento, discos foliares foram imersos durante 30 segundos em uma solução de 0,05% de cada tratamento e a testemunha em água destilada. Em seguida, os discos foliares foram colocados, dois a dois (tratado e testemunha) em placas de petri com tampas contendo abertura no centro coberta com tecido tipo “voil”, contendo solução ágar-água a 1%, unidos por uma tira de papel. No retângulo de papel foram colocados adultos ápteros de A. craccivora. Foram testados os óleos essenciais: alecrim (Rosmarinus officinalis), copaíba (Copaifera langsdorfii), menta (Mentha L.) e citronela (Cymbopogon winterianus) e três óleos fixos de pequi (Caryocar brasiliense), girassol (Helianthus annuus) e mamona (Ricinus communis). Os dados coletados foram registrados no período de 48h. O número de fêmeas atraídas e de ninfas produzidas, foram analisados pelo teste não-paramétrico x2 (qui-quadrado). O óleo essencial de C. winterianus teve maior repelência e menor produção de ninfas, o óleo de R. communis não apresentou efeito significativo de repelência, aumentando a produção de ninfas e os óleos essenciais R. officinalis, C. langsdorfii e Mentha L. e os óleos vegetais C. brasiliense e H. annuus, apresentaram efeito significativo na redução de ninfas.

ABSTRACT In Brazil, there are few records of insects associated with the cultivation of lima beans; among them, there is the black aphid Aphis craccivora Koch, 1854. The objective of this study was to evaluate the effects of silicon application on the resistance induction of lima bean plants, Phaseolus lunatus, to the black aphid A. craccivora. The experiment was conducted in the Entomology Laboratory of the Phytosanitary Sector of Centro de Ciências Agrárias, Universidade Federal do Piauí (UFPI), Brazil. The effects of the following treatments on biological aspects of the insect were evaluated: silicon applied to soil; silicon applied to soil + leaf; silicon applied to leaf; and control, without silicon application. The following biological variables were evaluated: generation period, reproductive period, and the fertility and daily average of produced nymphs per female. Plant silicon and lignin content were also evaluated. A 1% solution of silicic acid (2.0 g of product diluted in 200 mL of water) was applied around the plant stem (on soil), 15 days after emergence. Leaf application was performed with a 1-L spray, 5 days after the soil application. The non-preference of A. craccivora on lima beans was also evaluated. The evaluations were performed after 48 and 72 hours of infestation by counting nymphs and adults at each leaf section. Silicon application reduces nymph production, thereby interfering in the biological aspects of A. craccivora. Therefore, it can be used in cowpea pest management programs.

Botanicals are promising and attractive alternatives for pest management. In the present study, three botanical oils namely neem (Azadirachta indica), karanja (Pongamia pinnata) and mehogony (Swietenia mahagoni) were tested against the nymphs of Aphis craccivora Koch to evaluate the toxic and repellent effects under laboratory conditions (25 ± 5oC, 65-75% RH). Four concentrations (0.5, 1.0, 1.5, and 2.0%) along with control were maintained with distilled water and tween-20 was used as emulsifier. Leaf dipped method were used for insect bioassay. Insect mortality was recorded at 24, 48 and 72 hours after intervals while repellency was carried out at 2 hours after intervals upto 10th hours and the collected data were analyzed through MSTAT-C program. Results indicated that all the tested oils had toxic and repellent effects against the A. craccivora nymphs. Among the tested botanical oils, no significant difference was observed in terms of mortality over treatment time. But significant difference was noticed over level of concentrations exerted by the botanical oils. The average highest mortality (28.62%) was recorded by the application of mehogony oil whereas neem oil showed the lowest mortality (27.21%) against the A. craccivora and the mortality was directly proportional to the level of concentrations and hour after treatment (HAT). Probit analysis showed the lowest LD50 values of mehogony oil which revealed the highest toxic effect against the nymph of bean aphid. The highest repellent effect (77.33%) was found in mehogony oil (repellent class IV) among all the botanical oils applied. On the contrary, neem (57.33%) and karanja (55.00%) oils belonged to the same repellent class that is repellent class II. Although all the tested botanical oils evaluated showed toxic and repellent effects but mehogony oil performed as the best potent oil against the nymphs. We therefore suggested using the mehogony oil for the management of bean aphid. SAARC J. Agric., 19(1): 139-154 (2021)

AbstractIn two trials, at Chitedze, Malawi, in 1966–1967, the spread of rosette virus disease in groundnuts (Arachis hypogaea) intersown with field beans (Phaseolus vulgaris) was less than the spread in groundnut monocultures comprising plant populations equivalent to the number of groundnut plants and to the total number of plants in the intersown crop. In one trial, numbers of early rosette transmissions were related to numbers of alate Aphis craccivora Koch, the vector of the virus, found on groundnut plants. Immigrant alate A. craccivora settling on the intersown crop were trapped by the hooked epidermal hairs of the bean plants and the observed reduction of rosette infection in the intersown crop was attributed to this effect. Inter-sowing with beans is considered less effective than early-sown, high-density monoculture as a method of reducing groundnut rosette infections and yields of groundnuts from inter-sown crops may be lower than those obtained from high-density monoculture.

O caruncho, Callosobruchus maculatus (Fabr.), é considerado a praga mais importante do caupi, Vigna unguiculata (L.) Walp., armazenado em regiões tropicais e subtropicais. Visando minimizar os efeitos indesejáveis dos inseticidas químicos sintéticos, o controle dessa praga com óleos de origem vegetal vem se constituindo numa alternativa promissora, de baixo custo e segura para os aplicadores e consumidores. Foram testados os óleos essenciais [(Cymbopogon martini (Roxb.) J.F. Watson], Piper aduncum L., Piper hispidinervum C.DC., Melaleuca sp., Lippia gracillis Shauer) e fixos (Helianthus annuus L, Sesamum indicum L, Gossypium hirsutum L., Glycine max (L.) Merr. e Caryocar brasiliense Camb.), em grãos de caupi, cv. Sempre Verde. Os óleos foram utilizados nas concentrações 10, 20, 30, 40 e 50mL/20g, correspondendo a 0,5, 1,0, 1,5, 2,0 e 2,5 L/t e impregnados aos grãos no interior de recipientes de plástico, com auxílio de pipetador automático e agitados manualmente durante dois minutos. Parcelas de 20g de caupi foram infestadas com oito fêmeas de C. maculatus, com 0 a 48 h de idade. Cada óleo foi testado, separadamente, em delineamento inteiramente casualisado com seis repetições. Os óleos essenciais de C. martini, P. aduncum e L. gracillis causaram 100% de mortalidade em todas as concentrações, P. hispidinervum a partir de 1,5 L/t e Melaleuca sp. nas concentrações de 2,0 e 2,5 L/t. A redução do número de ovos viáveis e de insetos emergidos foi de 100% para todos os óleos essenciais, exceto Melaleuca sp. Por outro lado, os óleos fixos, apesar de apresentarem baixa mortalidade em todas as concentrações testadas, reduziram em praticamente 100% o número de ovos viáveis e de insetos emergidos.
