In this paper we examined the conidial attachment of Metarhizium anisopliae on the southern green stink bug, Nezara viridula, using the exuvia and nymphal stage of the host as a subtrate for M. anisopliae conidiospores. Initial studies using fluorescein isothiocyanate (FITC)-labeled conidia examined the differential binding of conidia to various sites on the cuticle. Both the topography and the chemistry of the cuticle affected conidial adhesion. Conidia were trapped in areas containig large numbers of setae (e.g., antennal tips, apical portions of tibia and tarsi). Chemical treatments to remove the cuticle proteins did not affect conidial adhesion, but solvent extraction of cuticular lipids significantly reduced the adhesion of M. anisopliae spores. Germination of M. anisopliae conidia attached to N. viridula cuticle was much less than conidia attached to other insect cuticle substrates. Afer a 24-hr incubation, only 5-20% of the conidia produced detectable germ tubes. The aldehyde (E)-2- decenal, a primary component of the stink bug scent gland, was detected in cuticle extracts and found to be selectively fungistatic to certain entomopathogenic fungi, including M. anisopliae. The hydrocarbon fraction (nC13 and nC21 to nC31 hydrocarbon series) served as a binding substrate for M. anisopliae, but conidia did not degrade these hydrocarbons and did not use them as a carbon source. |

Abstract: Integrated crop-livestock-forest (ICLF) systems involve intercropping of various crops to achieve beneficial and synergistic outcomes, enhancing both economic viability and environmental sustainability. Considering the complexity of integrated agrosystems and the economic importance of soybean production in Brazil, we aimed to investigate the effects of two ICLF systems on the physical characteristics and quality of soybeans produced. The treatments comprised plots (two ha) with either single-row (ICLFS) or triple-row (ICLFT), tree configurations intercropped with soybean (maize and forage grass), and control plots (one ha), whose crops were cultivated under full sunlight (CFS). Soybeans were harvested from plants located at 3, 6, 10 and 15 m from tree bands in the north and south faces of the ICLF systems and at random positions in the CFS plots. The moisture content, electrical conductivity of the exudate solution, hue angle and chroma index of grains harvested from ICLFS and ICLFT were similar to those of CFS-grown soybeans. However, the mass of 1000 grains and the bulk density values of ICLF-grown soybeans were significantly higher (P ≤ 0.05) than those of grains harvested from CFS plots. We conclude that the quality of soybean seeds was not negatively affected by the conditions prevailing in the ICLF systems. Moreover, it appears that the forest component contributed positively to the ecosystem by providing a favorable microclimate for the development of soybean grains.
