Abstract

Helicoverpa armigera is one of the most important agricultural pests because it has a high reproductive rate and resulted in economic losses. One of the H. armigera control techniques that is in accord with IPM principle is the utilizing of entomopathogenic fungus. The aim of this research was to test the pathogenicity of Lecanicillium (Lecanicillium sp. PTN01) against H. armigera. Pathogenicity test was conducted by conidia application of Lecanicillium sp. PTN01 on both the larvae and eggs at density of 105, 106, 107 conidia/ml. The control group was only treated with steril water. Polymerase chain reaction (PCR) was performed for molecular identification Lecanicillium sp. PTN01. The results showed that Lecanicillium sp. PTN01 able to inhibit egg hatching 13.75%, and cause mortality of first instar larval survival 98.75%. The result of virulence test to the highest larval mortality at 107 conidia/ml density was 41,25%, with the values of LT25, 50, 75 were 3.95, 7.12, 12.82 (days) and LC25, 50, 75 were 4.6 x 105, 1.7 x 106, 4.6 x 109 (conidia/ml). The DNA sequence analysis of ITS 1 and ITS 4 primers showed that Lecanicillium sp. PTN01 was similar to fungus species L. kalimantanense strain BTCC F23 with 94% homology.

Abstract

Pest infestation is a major problem in corn cultivation because it causes a decrease in crop productivity or even crop failure. This study aimed to evaluate the level of crop damage caused by Helicoverpa armigera and Ostrinia furnacalis in three tropical altitude variations. Ten hybrid corns from cross-breeding strains and three commercial hybrid corn varieties were evaluated at three locations with different altitudes, classified as lowland (30 masl), midland (600 masl), and highland (1000 masl). The evaluation was carried out on the level of crop damage and plant resistance. The results showed that the highest percentage of H. armigera attack on hybrid corn was 75% at Caps 17B x Caps 23 (moderately susceptible) at the lowland and the lowest was 8% at Caps 2 x Caps 17A (resistant). The percentage of H. armigera attack was 100% at Caps 15 x Caps 22 (very susceptible) and the lowest was the evaluation of Caps 5 x Caps 17B was 58% (susceptible) at the midland. Meanwhile, the highest attack percentage was 92% on the Caps 17A x Caps 17B, Caps 17A x Caps 22, and Caps 5 x Caps 22 hybrids (very susceptible), while the lowest was 67% on the Caps 3 x Caps 17B and Secada hybrids (moderately susceptible) at the highland. O. furnacalis attack showed that all hybrid corns were classified as resistant except for Caps 5 x Caps 22 and Paragon was moderately resistant with a percentage attack of 25% at lowland. At the midland, Caps 5 x Caps 17B hybrid corn was classified as very susceptible with an attack of 92%, while Caps 15 x Caps 22 was classified as resistant with an attack percentage of 8%. At an altitude of 1000 masl, Caps 17A x Caps 17B, Caps 3 x Caps 17A, and Caps 5 x Caps 17B were moderately resistant with an attack percentage of 33% and other hybrids were resistant with an attack percentage of 8%.

Abstract

Pest infestation is a significant challenge in corn cultivation due to the potential damage it can cause, leading to reduced crop productivity or even complete crop failure. This study aims to assess the infestation of Spodoptera frugiperda on corn in Bengkulu, considering various elevations. Ten hybrids resulting from crosses between promising lines (Caps 2 x Caps 17A, Caps 3 x Caps 17A, Caps 3 x Caps 17B, Caps 5 x Caps 22, Caps 5 x Caps 17B, Caps 15 x Caps 22, Caps 17B x Caps 23, Caps 17A x Caps 17B, Caps 17A x Caps 22, Caps 22 x Caps 23) and three commercial hybrid varieties (Bonanza, Paragon, and Secada) were evaluated across three locations at different elevations: lowland (30 meters above sea level) (masl), midland (600 masl), and highland (1000 masl). The assessment focused on the extent of damage and the plant’s resistance to S. frugiperda infestations. The infestation of S. frugiperda is higher at an elevation of 30 masl compared to locations at 600 masl and 1000 masl. Scoring leaf damage caused by S. frugiperda infestation at 30 masl: 2.73–4.86, at 600 masl: 2.73–3.55, and at 1000 masl: 2.4–3.37.

Abstract

Etiella zinckenella is a significant pest of peanuts in Indonesia, causing pod yield losses of up to 100% in infested fields. This study aims to identify an appropriate strategy for the sustainable management of E. zinckenella by validating the effectiveness of various integrated pest management approaches through field trials. The experiment was conducted in two locations, Natar (Lampung) and Muneng (East Java), using 11 treatment combinations with three replications. The peanut variety planted was Gajah (GH 51). The treatments included a range of pest control technologies, such as seed treatment with thiamethoxam, application of carbofuran, neem seed powder (NSP), release of Trichogrammatoidea bactrae-bactrae, application of Spodoptera litura Nuclear Polyhedrosis Virus (SlNPV), trap crops (Crotalaria, soybean, maize, mung bean), organic fertilizer, and lambda-cyhalothrin. The findings revealed that the population density of pod borers and the extent of pod and seed damage were higher in Natar than in Muneng. In Natar, pod damage ranged from 43.7% to 76.3%, with the highest levels recorded in untreated plots and those treated with lambda-cyhalothrin. Similarly, the highest pest population densities in Natar were observed in untreated plots and those treated with lambda-cyhalothrin. In contrast, Muneng exhibited significantly lower pod damage, ranging from 0.2% to 2.6%, with the highest recorded damage at 2.64%. The most effective pest management strategy in both locations was a combination of thiamethoxam seed treatment, carbofuran, NSP, T. bactrae-bactrae, SlNPV, and Crotalaria trap crops, which reduced pod damage to 43.7% in Natar and 0.2% in Muneng. These results suggest that an integrated pest management approach effectively mitigates E. zinckenella infestations in endemic areas. This method not only minimizes pest damage but also helps maintain populations of natural enemies, including Formicidae, Coccinella sp., Paederus sp., and Oxyopes sp., thereby supporting ecological balance. Furthermore, trap crops such as maize, soybean, and mung bean, when planted around peanut fields, demonstrated considerable efficacy in reducing pest attacks compared relative to chemical insecticides, highlighting their potential for a sustainable pest management strategy.
