ABSTRAK Entomopatogen dari genus Steinernema berpotensi digunakan sebagai pengendali berbagai serangga hama, terutama ordo Lepidoptera, seperti Helicoverpa armigera. Penggunaan Steinernema untuk pengendalian H. armigera akan menguntungkan karena aman terhadap lingkungan, mudah diproduksi massal, toleran terhadap berbagai macam pestisida, dapat aktif mencari serangga sasaran, tidak menyebabkan resisten dan resurjensi, serta dapat diaplikasikan dengan alat semprot standar. Namun, formula pestisida hayati mengandung Steinernema masih sangat terbatas. Tujuan penelitian adalah membuat formula Steinernema sp. yang efektif terhadap hama penggerek buah kapas (H. armigera). Penelitian dilaksanakan di laboratorium Patologi Serangga, Balai Penelitian Tanaman Pemanis dan Serat, Malang mulai bulan Mei-Juli 2010. Larva instar III Steinernema sp. dibuat dalam 6 macam formula perlakuan dengan bahan pembawa (carrier) berbeda-beda, yaitu (1) suspensi (akuades + sukrosa), (2) pellet-2 (sekam padi), (3) pellet-1 (tanah liat + arang), (4) agar + spon, (5) kapsul (Ca-alginat), dan (6) kontrol (akuades). Setiap formula diinokulasikan 10 6 juvenil infektif (JI). Masing-masing perlakuan disusun dalam rancangan acak lengkap (RAL) dengan tiga kali ulangan. Penurunan jumlah juvenil infektif (JI) pada setiap formula yang diamati per minggu selama ± 4 minggu. Isolat yang digunakan untuk penelitian ini berasal dari Asembagus. Untuk mengevaluasi efektivitas formula, larva H. armigera diperlakukan dengan JI yang berasal dari masing-masing formula setiap minggu selama empat minggu. Perlakuan ini menggunakan rancangan acak lengkap dengan empat ulangan. Jumlah penurunan JI setiap minggu selama empat minggu setelah perlakuan. Persentase JI yang hidup pada pellet-1, suspensi, pellet- 2, agar + spon, kapsul, dan kontrol berturut-turut sebesar 53; 12,4; 44; 63,8; 17,6; dan 5%. Pada minggu pertama sampai minggu keempat setelah perlakuan terlihat bahwa formula yang paling baik mempertahankan JI adalah agar + spon dan kemudian berturut-turut diikuti oleh pellet-1, pellet-2, kapsul, suspensi. Steinernema sp. yang disimpan selama empat minggu dalam berbagai bentuk formula terhadap H. armigera berkisar antara 80-99%. Formula agar dan spon paling baik untuk menyimpan Steinernema sp. selama empat minggu, karena formula ini memberikan tingkat viabilitas dan efektivitas Steinernema sp. paling tinggi. Kata kunci : efektivitas, formula, Helicoverpa armigera, Steinernema sp., viabilitasABSTRACT Entomopathogenic nematodes genus Steinernema for are potential to be used as a control for various insect pests, especially ordo Lepidoptera, such as Helicoverpa armigera. The use of Steinernema to control H. armigera is beneficial because it is environmentally friendly, easy to produce, tolerant to several pesticides, actively search the target insect, does not cause resistance and resurgence, and can be applied by using standard sprayer. Unfortunately, biological pesticide containing Steinernema is still limited. The study was aimed at formulating a biological agen containing Steinernema sp. to control the cotton bollworm weevil (H. armigera). The experiment was conducted at insect pathology laboratory, Indonesian Sweetener and Fiber Crops Research Institute, Malang from May to July 2010. Steinernema sp. instar III larvae was formulated in six different forms such as Pellet-1 (clay+carbon), suspension (distilled water+sucrose), Pellet-2 (rice husk), agar+sponge, capsule (Ca-alginate), and control (distilled water). Each formulation was inoculated with 10 6 Infective Juvenile (IJ). Each treatment was arranged in completely randomized design (CRD) with three replicates. Each formulation observed showed decrease in IJ number every week for + 4 weeks. Isolates used for this research were originated from Asembagus experimental station. For evaluation of the formulation effectiveness, H. armigera larvae was treated using IJ from the formula weekly for four weeks. On the first week after treatment, the percentages of living IJ in Pellet-1, suspension, Pellet-2, agar+sponge, capsule, and control were 53; 12.4; 44; 63.8; 17.6; and 5%, respectively. Effectiveness of Steinernema sp. stored for four weeks in various formulations against H. armigera ranged from 80-99%. The best formula of Steinernema sp for storage was agar+sponge because of its ability to viability and effectiveness of Steinernema sp.

AbstractDifferent Shin-Etsu twist-tie rope formulations, containing either the cotton bollworm, Helicoverpa armigera (Hübner) pheromone or pink bollworm, Pectinophora gossypiella (Saunders) pheromone, or both, in the same rope, were tested in Israel for mating disruption. The success of mating disruption was evaluated by the mating table technique, comparing the percentage of mating of virgin sentinel females in pheromone-treated and control plots. Two variants of this technique were evaluated, one with two mating tables per plot, each containing five to seven females, and the other with six to eight mating tables per plot, with only one female per table. The latter method was more sensitive than the former, particularly at low population densities. Two tests were conducted in 1995 in order to compare a blend of five components of H. armigera pheromone with a blend of two components for mating disruption. The application consisted of 2000 ropes/ha, each with 80 mg pheromone. Evaluation by the two mating table methods showed clearly that the formulation containing two components was superior to the five-component blend for mating disruption, suppressing mating almost completely for 49 days. A new combined formulation, HPROPE, containing 175 mg of the H. armigera two component blend and 65 mg of P. gossypiella pheromone was tested in 1996 for mating disruption of both pests. Application of 625 ropes/ha caused a high level of suppression of mating of H. armigera females for at least 94 days and that of P. gossypiella females for 161 days. The pheromone release rates were c. 625 mg/day/ha for H. armigera and 162 mg/day/ha for P. gossypiella. A ‘long-life’ formulation of P. gossypiella pheromone, PBW rope LR, applied at 125 ropes/ha releasing 137 mg/day/ha achieved complete suppression of mating over 75 days. This release rate of P. gossypiella pheromone was much lower than that currently used in Israel (275 mg/day/ha). The present study indicates that mating of females of two moth pests with different pheromones can be disrupted by one combined formulation.

Helicoverpa armigera (Hübner, 1805) (Lepidoptera: Noctuidae) is a cosmopolitan pest with wide geographical distribution in Brazil. This pest was officially registered in 2013 on cotton, soybean, corn, and some weeds, although this species may have been present in the country since 2008. The objective of this work was to evaluate the efficiency of eight insecticides (seven chemicals and a biological product) to control small and large H. armigera caterpillars. The experiment was conducted under laboratory conditions (T 22±1 °C; RH 70±10%; 12h photoperiod), with nine treatments (g a.i./ha dose): flubendiamide (72), chlorantraniliprole + lambda-cyhalothrin (30 + 15), chlorfenapyr (288), spinetoran (18), indoxacarb (120), emamectin benzoate (10), metomil (322.5), Bacillus thuringiensis (500), and control (water). A completely randomized design was used with four replications for each size of caterpillars (small and large), and each repetition (plot) consisted of five H. armigera caterpillars fed with bean leaves immersed in the different treatments evaluated. The larval mortality evaluations were performed at one, three, five, and seven days after contact with the treated bean leaves, determining the control efficiency (E%) through the formula of Abbott (1925). All chemical and biological treatments tested caused significant mortality of small and large H. armigera caterpillars, reaching a control percentage of 100% at seven days after treatment, demonstrating the possibility of using the insecticides tested to control this pest under field conditions.

Helicoverpa Armigera Hubner

The addition of synthetic (E)-anethol to the known attractant phenylacetaldehyde synergized attraction of the cotton bollworm Helicoverpa armigera, the blend invariably catching 4 to 6 times more than phenylacetaldehyde on its own. Highest catches were recorded by the 1:1-3:1 blends. The addition of salicyl aldehyde, ±linalool, (R)-(+)-limonene, 2-methoxybenzyl alcohol and 4-methoxybenzyl alcohol (compounds described earlier in the literature as co-attractants for H. armigera), increased catches when added to phenylacetaldehyde. However, the addition of these compounds did not increase catches of the (E)-anethol+pheny- lacetaldehyde blend. When directly compared with performance of the synthetic pheromone, the (E)-anethol +phenylacetaldehyde blend caught an average of 27% of the catch in pheromone baited traps. On an average 79% of moths caught in traps with the (E)-anethol+phenylacetaldehyde blend were females, while traps with pheromone caught only males. The (E)-anethol+phenylacetaldehyde blend described in this study may form the basis for the development of an efficient bisexual lure for H. armigera AFTER further optimization.
