Efeito de espécies vegetais em bordadura em cebola sobre a densidade populacional de tripes e sirfídeos predadores

Abstract: Effect of different species of border plants on the population density of thrips and syrphids predators in onion cropThe effect of planting different species of border plants on the population density of thrips (Thrips tabaci Lind), and syrphid predators (Toxomerus spp.), population density were evaluated at EPAGRI, Santa Catarina State, Brazil. The research was carried out from August to December 1998. The treatments were onion monoculture; onion intercropped with buck wheat (Fagopyrum esculentum Moench) (Pol… Show more

“…Therefore, the main phytophagous species were more abundant in onion plants 30 m from marigold, while the main predators were more abundant in plants close to the attractive species. However, Gonçalves & Souza-Silva (2003), studying only T. tabaci and Toxomerus spp. (Diptera: Syrphidae) populations in relation to different plant species in rows surrounding the onion field, observed no population decrease of the pest species.…”

“…No sistema de cultivo de alface com cenoura (Consorcio II) foi registrado o menor diâmetro comparado com os outros tratamentos, para o cultivo solteiro da alface não diferiu estatisticamente do consórcio alface com cebola (Consócio I). Discordando destes resultados, Bezerra Neto et al (2003) observaram, com relação ao diâmetro de plantas de alface no sistema de cultivo solteiro, que os valores maiores foram obtidos quando consorciados com cenouras.…”

“…O consórcio de culturas tem sido uma das formas de aumento da produtividade e do lucro por unidade de área entre os pequenos produtores rurais em regiões tropicais (BEZERRA NETO et al, 2003), onde os fatores climáticos, como temperatura e energia luminosa, não apresentam limitações. Arranjos espaciais, épocas de semeaduras e cultivares são importantes fatores de manejo que podem ser manipulados, com o objetivo de aumentar a eficiência na prática de consórcios em hortaliças (NEGREIROS et al, 2002).…”

“…They are native to Mexico and Central America (Peres, 2007;Santos, 2013). Among the species of this genus, Tagetes patula points out for being used due to its effect of attractiveness or repellency of insects (Gonçalves and Silva, 2003;Peres., 2007;Silveira et al, 2009). Besides, it is popular for having medicinal properties, such as analgesic, antispasmodic, immune stimulant, laxative and anthelmintic (Duque, 2006;Priyanka et al, 2013) and bactericidal (Rondón et al, 2006;Jain et al, 2012).…”
