Microbial Biopesticides in Agroecosystems [PDF]
Microbial biopesticides include several microorganisms like bacteria, fungi, baculoviruses, and nematode-associated bacteria acting against invertebrate pests in agro-ecosystems. The biopesticide sector is experiencing a significant growth and many discoveries are being developed into new biopesticidal products that are fueling a growing global market ...

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

Syndromic convergence (SyCo) reframes aquaculture disease as the synergistic product of climate‐driven stressors, pathobiome communities, and host immune compromise, not single pathogens. A five‐criterion scoring matrix, composite early warning index, and three‐layer intervention framework together operationalize this shift toward predictive ...

ABSTRACT Rationale Bioactive (E)‐stilbenoids in vine extracts are prone to light‐induced transformation into the respective (Z)‐isomers and further degradation products, often resulting in a loss of bioactivity. We sought to study stilbenoid degradation beyond that of the well‐researched resveratrol due to the high diversity of stilbenoids in nature ...

ABSTRACT Background and Aims Overuse and misuse of chemical pesticides remain a major threat to public health in agricultural communities of the least developed and low‐income countries. Gender‐based differences in agricultural settings, access to agricultural information, and decision‐making play a crucial role in influencing farmers' knowledge ...

ABSTRACT In the current era, climate change has emerged as a fundamental threat to African agriculture, driven by increasingly erratic climatic patterns such as prolonged rainfall, decadal droughts, and escalating thermal stress. This review evaluates contemporary agricultural productivity by gathering and analyzing empirical data from academic ...

Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Lethal (mortality) and sublethal (fecundity, fertility) effects of the biopesticide Prev‐Am Plus (containing ~6% sweet orange essential oil) were assessed on the tachinid fly Exorista larvarum. Mated females were exposed via contact and oral routes across five concentrations (0.25%–20%) using protocols adapted from Apis mellifera.

This study assessed the non‐target effects of commonly used agrochemicals on the egg parasitoid Trichogrammatoidea cryptophlebiae, an important biological control agent in South African orchards. Agrochemical impacts varied across life stages, with several insecticides allowing adult survival but significantly reducing parasitism and developmental ...
