Minyak kelapa sawit adalah salah satu komoditas perkebunan diIndonesia dan telah tersebar luas di Indonesia. Salah satu hama yang menyerang kelapa sawit adalah serangga, dan hama yang paling merusak biasanya dari Lepidoptera. Tujuan dari penelitian ini adalah untuk menentukan parasitoid yang memparasitisasi hama pemakan daun kelapa sawit di perkebunan kelapa sawit PTPN VIII Cindali, Bogor. Penelitian dilakukan di 6 blok perkebunan kelapa sawit PTPN VIII Cindali dari September 2014 -Juni 2015 dengan pengamatan sebulan sekali. Sampel diambil dengan cara masing-masingblok diambil 5 tanaman di setiap plot secara acak untuk diamati dan serangga pemakan daun palem diambil untuk disimpan sampai parasitoid muncul. Parasitoid yang keluar kemudian dihitung dan diidentifikasi. Hasil penelitian menemukan 6 spesies hama pemakandaun palem dan 5 spesies Hymenoptera parasitoid yang memparasit hama ini. Hama yang ditemukan adalah Setora nitens, Amatissa sp., Birthosea bisura, Mahasena corbetti, Metisa plana dan Pseudococcus sp. Sedangkan parasitoid yang ditemukan adalah Spinaria spinator, Charops bicolor, Telenomus podisi, Aphanogmus sp. dan Acerophagus sp.

ABSTRACT The use of pesticides in the soybean crop may impair the biological control, if the products are not selective to Telenomus podisi and Trissolcus basalis, which are important stink bug egg parasitoids. This study aimed to assess the selectivity of 15 pesticides registered for soybean crop on adults of T. podisi and T. basalis. Three laboratory bioassays were performed, totaling 18 treatments, in a completely randomized design, with four replications. The insecticides (g or mL of a.i.) imidacloprid + beta-cyfluthrin (0.25 + 0.03), deltamethrin (0.06), thiamethoxam + lambda-cyhalothrin (0.27 + 0.35), acephate (1.87) and fenitrothion (1.25) are harmful to both parasitoids species. Flubendiamide (1.20), diflubenzuron (2.00), Bacillus thuringiensis (0.08) and lufenuron (0.12) are innocuous to both parasitoids. The fungicides azoxystrobin + flutriafol (0.31 + 0.31), trifloxystrobin + prothioconazole (0.37 + 0.44), pyraclostrobin + metconazole (0.33 + 0.12) and trifloxystrobin + cyproconazole (0.94 + 0.40) are innocuous to T. podisi, but slightly harmful to T. basalis. The herbicides glufosinate ammonium salt (0.50) and glyphosate isopropylamine salt (1.20) are innocuous to both parasitoids.

O potencial reprodutivo e a longevidade do parasitóide de ovos Telenomus podisi Ashmead foram estudados, em laboratório, em ovos dos percevejos hospedeiros Euschistus heros (F.), Piezodorus guildinii (West.) e Nezara viridula (L.). A capacidade reprodutiva e a longevidade de fêmeas de T. podisi foram significativamente diferentes nas três espécies de percevejos. A maior produção de descendentes por fêmea ocorreu nos primeiros 10 dias de vida, em ovos de E. heros e P. guildinii. O parasitismo em N. viridula foi muito baixo (8,1%) e somente cinco indivíduos completaram seu desenvolvimento. Fêmeas jovens geraram maior número de fêmeas do que de machos, ocorrendo proporção inversa com o avanço da idade da fêmea. A razão sexual do parasitóide quando desenvolvido em E.heros e P. guildinii foi de 0,67 e 0,61 e a fertilidade média da fêmea durante a sua vida reprodutiva foi de 211,0 e 76,1 descendentes, respectivamente. A longevidade das fêmeas de T. podisi foi diferente em cada espécie hospedeira, vivendo, em média, 19,9, 30,9 e 40,6 dias quando parasitaram ovos de P. guildinii, E. heros e N. viridula, respectivamente. Os machos, entretanto, tiveram sempre longevidade maior em relação às fêmeas, apresentando um tempo de vida semelhante nos três hospedeiros (32,0, 34,5 e 43,5 dias, respectivamente). Os resultados sugerem que E. heros e P. guildinii são os hospedeiros mais adequados ao desenvolvimento de T. podisi.

Rice Stink Bug

Biological control of Oebalus insularis eggs is considered an important strategy in the control of this rice “stink bug”. Effects of essential oils (EOs) from Piper jacquemontianum Kunth and Piper marginatum Jacq. (Piperaceae) on the viability of parasitized and unparasitized eggs by Telenomus podisi, in concentrations of 0.5 to 2.0%, were evaluated. EOs from both species at a concentration of 2% affected the development of embryons of O. insularis as well as of T. podisi after 24 and 48h of their administration. In both species, P. jacquemontanium and P. marginatum LC50, 24 h before the application of treatments on eggs of O. insularis was 3.835 y 3.037, respectively. LC50 after 48 h of treatment with EOs showed contrasting results which varied from 2.207 and 1.811. for P. jacquemontianum and P. marginatum, respectively. LC50 calculated before 24 h in parasitized eggs of O. insularis by T. podisi, was 3.037 and 2.171 for P. jacquemontianum y P. marginatum, respectively, while after 48h of treatment it was 1.166 y 1.935, respectively. Absorption of the EO components by the unparasitized and parasitized eggs of O. insularis by T. podisi was higher after 48 h of exposition. This is due to the longer exposure time, which allows higher penetration of the EOs into the interior of insect eggs by microscopic pores and micropyle.
