Abstract
The effects of alternative inputs on the oviposition and viability of Leucoptera coffeella eggs and larvae were evaluated. Under controlled conditions, coffee seedlings cv. IAPAR-59, eight months old, were sprayed with brown propolis extract (1%), pyroligneous extract with pepper and garlic (PEPG) (2%), silicate clay (2%), kaolin (5%), lime sulfur (2%), neem oil (1%) and kaolin + neem oil (5% + 1%), distilled water and no apraying. In a first no-choice bioassay, coffee seedlings were sprayed before oviposition and kept in cages where adult insects within three days after emergence were released. Adults remained in the cages for 24 hours. Eggs were then recorded. A portion of these eggs were removed but 10 eggs per seedling were preserved to access larval mortality. Reduction of the number of eggs by propolis extract, neem oil, kaolin + neem oil and PEPG were observed in the evaluations. Treatments with neem oil caused great larval inviability. Treatments were also sprayed on eggs laid on leaves. Eggs viability was reduced by neem oil containing treatments and lime sulfur. Neem oil treatments made unfeasible adult emergence; intermediate viability on lime sulfur and slight inviability on silicate clay. Finally, treatments were also sprayed on leaves hosting first or third instar larvae. Neem treatment caused high mortality for 1st and 3rd larvae which was reduced when mixed with kaolin. However, these negative effects disappeared when considering adult survival. Results indicated that propolis extract, PEPG and neem oil treatment are suitable for reducing egg deposition and neem oil diminishes markedly larvae survival and adult emergence.
