Abstract

Lepidopteran pests such as S. litura might cause yield losses in many crops especially during pest outbreak. The combinations of microbial and botanical insecticides were expected to increase the effectivity in controlling the respected insect pest. This research aimed to evaluate the combination of plant extracts and B. bassiana to control S. litura. The compatibility of B. bassiana with different plant extracts such as Neem, Chinaberry, Mexican Sunflower and Lantana leaves was studied in the laboratory. The compatibility was evaluated based on B. bassiana colony growth, conidia density, conidia viability, and mortality of S. litura larvae. After 12 days after application (DAA), colony growth of B. bassiana was reduced by all plant extract treatments. For the mortality of S. litura, the combined mixture of B. bassiana and 0.25% Chinaberry extract resulted the maximum mortality rate (44%). After 12 and 15 DAA, the 0.25% Chinaberry showed the highest colony growth (3.93 and 4.37 cm). The most suitable treatment was B. bassiana with 0.25% Chinaberry that had the conidial density at 1.77 x 108 conidia/ml and conidial viability of 75.63% and can enhanced the mortality of S. litura larvae.

Abstract

This study aims to determine the pathogenicity and feeding inhibition of three B. bassiana isolate strains with different densities and concentrations of EDT (Tobacco Leaf Extract) in controlling P. xylostella. Research conducted in the Lab. Brenjonk Biological Agency and Lab. BPTPH Pasuruan from October to December 2022. This study used a Randomized Block Design (RAK) to examine the mortality and feeding inhibition of B. basiana and EDT strain isolates against P. xylostella. And probit analysis to find out the LC50 value and LT50 value. In this study, there were 17 treatments consisting of 15 larvae in each treatment and 4 repetitions were carried out. The results showed that the highest mortality percentage of P. xylostella was found in B. bassiana isolates of Bojonegoro and Jatisari strains at densities of B. bassiana 108 and 1010. The lowest LC50 value of B. bassiana isolates was the Bojonegoro strain and the EDT LC50 value was 43.79 ml/lt. Meanwhile, the lowest LT50 value was found in the EDT treatment at 28.40 hours. Based on the test results, it was also known that B. bassiana and EDT had potent feeding inhibition against P. xylostella. However, the use of EDT in controlling P. xylostella was less effective and efficient than the application of B. bassiana.

Abstract

Rice field bunds function as a reservoir of biodiversity, one of which is entomopathogenic fungi (EPF), which plays a role in controlling insect populations and increasing plant resistance. This study aimed to explore the interaction between organic matter content, soil pH, and EPF diversity in rice fields from Mulyoagung Subdistrict, Malang Regency. EPF was isolated using the insect bait method, followed by pathogenicity testing on Tenebrio molitor larvae. The Shannon-Wiener index (H'), evenness (E), and dominance (C) were used to assess the diversity of EPF on rice field bunds. Spearman correlation analysis was conducted to test the relationship between organic matter content, soil pH, and EPF diversity. Based on the results of the study, three genera of EPF were found in the rice fields, namely Beauveria, Fusarium, and Metarhizium. The presence of EPF is influenced by understory plants and the amount of organic matter in the soil. Therefore, preserving rice field bunds is very important to maintain the EPF population.
