Dinâmica populacional do parasitoide de ovos erythmelus tingitiphagus (hymenoptera: mymaridae) em clone de seringueira, em Itiquira, MT

Abstract: e Joaquim Manoel da Silva 3 RESUMO -O percevejo-de-renda Leptopharsa heveae Drake & Poor (Hemiptera: Tingidae) é uma das mais importantes pragas da heveicultura no Brasil, principalmente nas regiões Sudeste e Centro-Oeste. Devido ao seu hábito sugador, na face abaxial das folhas, esta praga leva à senescência precoce das mesmas e a reduções na produção de látex em até 30%. Dentre os inimigos naturais de L. heveae está o parasitoide de ovos Erythmelus tingitiphagus (Soares) (Hymenoptera: Mymaridae), regulando s… Show more

“…Despite their somehow restricted area-wide application, the environmental and economic impact of fungi for L. heveae management cannot be overlooked. For instance, Michelin ran an 8000 ha rubber tree operation in the Brazilian municipality of Itiquira (MT) during the 1978-2009 period (Costa 2015), and starting in 1993/1994, these fungi allowed a considerable reduction in the costs for L. heveae control, from US$ 45,000 in 1992/93 when only chemical insecticides were used, down to US$ 10,000 in the following agricultural year when the microbial biocontrol strategy was initiated (Val 1994;Santos & da Silva 2013). In addition to Michelin, some other large rubber operations in Brazil, such as Fazenda Triângulo, no longer mass produce fungi.…”

“…Reductions in latex production as high as 30% may occur when trees are sucked by lace bug nymphs and adults (Tanzini & Lara 1998). Tolerant clones, chemical insecticides, and biological strategies have been adopted to manage population outbreaks of L. heveae (Tanzini 1996, Alves et al 2003, Santos & da Silva 2013.…”
