Abstract

An alternative method for controlling Spodoptera frugiperda applies entomopathogenic fungi (EPF). The present research aimed to determine the impact of the endophytic EPF  on the growth and development of S. frugiperda. Twenty molecularly identified isolates of the endophytic EPF were used in seed treatments with the fungal suspension 1 × 1010 conidia.mL-1. The endophytic EPF that colonized corn leaves eaten by the neonate S. frugiperda larvae was able to significantly decrease the body weight of the larvae and pupae. The endophytic EPF could prolong the developmental time of all instar larvae and pupae.  The endophytic EPF could raise larval and pupal mortality and reduce the ability of adults to emerge from pupae,  and decrease egg laying by females.  The lowest percentage of adult emergence was observed in the adults from larvae consuming corn leaves colonized with Beauveria bassiana JaGiP and JgSPK isolates, which were 34.67% and 24%, respectively. Consequently, a reduced adult emergence could lead to a high cumulative death rate of 76% from larvae to adults. Finally, the endophytic EPFs negatively affect S. frugiperda growth and development.  B. bassiana JaGiP and JgSPK isolates are the most pathogenic fungi in inhibiting the growth and development of S. frugiperda. They are promising candidates for controlling S. frugiperda in the corn field.

Abstract

Insect pollinators are insects that play an important role in maintaining the existence of a plant species through pollination and maintaining the genetic diversity of plants in the population maintaining the existence of a plant species through pollination and maintaining the genetic diversity of plants in the population. Pollinator insects generally come from the Hymenoptera order. The purpose of this study was to determine the types of pollinator insect species that dominate coconut plantations in the Banyuasin area of South Sumatra. Data were collected by field observation using the plant survey method. The survey was conducted through direct observation of coconut plants owned by coconut farmers in the Banyuasin area. Observations were made on coconut plants by observing pollinator insect species that associate with flowers on coconut plants. Insect pollinator species found in coconut plantations in the Banyuasin area include Vespa affilish, Apis mellifera, and Apis dorsata. The most dominant type of pollinator insect found in coconut plantations in the Banyuasin area is Apis dorsata with 201 individuals. So, the results show that the abundance of individuals is high but has a low diversity index.
