Journal of Tropical Mycorrhiza is an international journal devoted to research into mycorrhizas - the widest symbioses in nature, involving plants and a range of soil fungi world-wide. The journal covers research into mycorrhizas, including molecular biology of the plants and fungi, fungal systematics, development and structure of mycorrhizas, and effects on plant physiology, productivity, reproduction and disease resistance. Coverage extends to interactions between mycorrhizal fungi and other soil organisms, and effects of mycorrhizas on plant biodiversity, ecosystem structure, reclamation and restoration of degraded land. Journal of Tropical Mycorrhiza presents original papers, short notes and review articles, along with commentaries and news items. It offers a platform for new concepts and discussions, and serves as the basis for a forum of mycorrhizologists from around the world.

ANTAGONISTIC ABILITY OF ENTOMOPATHOGENIC FUNGI METARHIZIUM ANISOPLIAE AND BEAUVERIA BASSIANA AGAINST MORTALITY OF WOOD GRASSHOPPER (VALANGA NIGRICORNIS) Mohamad, Danial; Lamangantjo, Chairunnisah

Abstract

The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana are potential biological control agents for suppressing the population of the wood grasshopper (Valanga nigricornis). This study aims to evaluate the antagonistic ability of the fungi M. anisopliae and B. bassiana against the wood grasshopper (Valanga nigricornis). This study is a descriptive study with a quantitative approach, applying inoculum suspension at four concentration levels (P1, P2, P3, and P4) and observing insect mortality and colony growth in culture media. The results showed that the P4 suspension treatment produced the highest mortality of 92% with a probit value of 1.28, while mortality in other treatments ranged from 0 to 75%. The highest infection viability showed that in the P4 treatment, the CFU value was 3.0×106 for M. anisopliae and 1.4×106 for B. bassiana. These findings indicate that high inoculum concentrations increase the antagonistic effectiveness and infection ability of entomopathogenic fungi.

Abstract

Information on the existence of indigenous Arbuscular Mycorrhizal Fungi (FMA) is needed as an early stage of FMA biofertilizer production to overcome the scarcity of subsidized fertilizers. The purpose of this study was to determine the type of indigenous FMA and determine the location that can be used as a source of FMA inoculum as a biological fertilizer material. Soil and root samples were observed in 4 types of land use, with 10 repeats. The results showed that for every 100 g of soil, the highest number of spores were found in natural forest types as many as 248 spores, in agroforestry land 138 spores, in ex-mining land 95 spores, and at least in sweet potato-intensive agricultural land only 58 spores. Natural forest areas have a high enough spore count so that natural forest locations have the potential to be a source of indigenous FMA inoculum than other types of land use. There are three genera of FMA found, namely Glomus, Gigaspora, and Acaulospora. Glomus is found on all types of land use except monoculture farmland and is the genus that dominates spore populations. The genus Acaulospora is found only in agroforestry land types. Indigenous FMA was found to be able to infect plant roots in natural forests in as much as 6 % and agroforestry land in as much as 16 % so it was included in the medium and low categories. Meanwhile, in the monoculture type of sweet potato and ex-mining land, no root infection was found.
