Abstract

Anthracnose is a disease caused by Colletotrichum sp., which can reduce the quality and yield of red chili by 45-60%. This study aimed to determine the ability of different Beauveria bassiana isolates to control anthracnose in chili. The research employed a Randomized Block Design (RBD) consisting of 6 treatments and 5 replications. The treatments included a control and 5 different B. bassiana isolates (PD114, TD312, WS, BbKo, KT2B21). The observed variables included incubation period, disease incidence and severity, plant height, number of leaves, flowering time, and chili fruit weight. The results showed that the application of different B. bassiana isolates have effectively inhibited the development of Colletotrichum truncatum, which caused anthracnose in chili. B. bassiana has demonstrated the ability to prolong the incubation period of C. truncatum (5.40 days) and reduce the percentage of disease incidence (16%). Furthermore, the application of B. bassiana increased the height of chili plants (40.40 cm) and the number of leaves (32 leaves), accelerated the flowering time (42.80 days), and boosted chili production (178.25 g). The WS and TD312 isolates revealed the most significant results. Although the severity of the disease was not impacted, the 2 isolates provided notable agronomic benefits to the chili plants.

Abstract

Spodoptera frugiperda J.E. Smith, sometimes known as armyworm, is a serious pest in maize crops. This pest affects maize plants' leaves, resulting in yield losses of up to 79.9%. Entomopathogenic fungi is one alternate method for controlling the pest. Various entomopathogenic fungus can be found in nature, one of which thrives endophytically on plants, such as Trichoderma asperellum. The purpose of this study was to obtain and evaluate T. asperellum's pathogenicity in suppressing S. frugiperda eggs. This investigation used five T. asperellum isolates (A116, PC21, S2D11, SD34, and AB2B3) obtained from diverse plant tissues. S. frugiperda larvae were treated with 2 mL of a conidia suspension containing 108 conidia/mL and sterile distilled water as a control. The observation variables comprised S. frugiperda egg mortality, first-instar larvae mortality, pupae formation percentage, and imago formation percentage. The findings indicated that the endophytic fungus T. asperellum can infect S. frugiperda eggs. The mortality rate for S. frugiperda eggs ranged from 43.27 to 78.34%. The mortality rate of first instar larvae ranged between 36.94% and 60.22%. The application of T. asperellum to S. frugiperda decreased pupae and imago production by 39.78% and 37.87%, respectively. T. asperellum SD324 is the most effective isolate for infecting S. frugiperda eggs. Keywords: endophytes fungus, entomopathogenic fungus, larvae, maize, Spodoptera frugiperda

Abstract

Beauveria bassiana is one of the entomopathogenic fungi to control various kinds of insect pests. Virulence of B. bassiana against insects could be affected by ultraviolet (UV) light. The study was aimed to determine the effect of different times of UV light exposure to B. bassiana against Spodoptera litura. The study was arranged in a Completely Randomized Design (CRD) with six different times of UV light exposure (control, 0, 15, 30, 45, 60 minutes) in four replications, respectively. Those B. bassiana were inoculated on the second instar of larvae of S. litura. The parameters observed were colony growth of B. bassiana, conidial germination, larval mortality, percentage of pupae, and adults formed. The data were analyzed by analysis of variance and LSD test at the 5% significance level. The results showed that exposure of B. bassiana to UV light reduced its germination but not inhibit the growth of B.bassiana. The exposure for 45 minutes and 60 minutes increased the virulence of B. bassiana that indicated by an increase of S.litura mortality (15.0-62.5%) and shorter LT50 (6.29-10.92).
