Dependence on multiple nutritional endosymbionts forming a metabolic unit has evolved many times in insect taxa that feed on nutritionally unbalanced diets. It has been shown that the distribution of nutrient biosynthesis between nutritional symbionts coexisting within the same host goes hand in hand with their assignment to distinct specialized ho...
This study investigated the effects of synbiotics on the early growth of okra (cv. Kirikou) and as biopesticides. The treatments included two probiotics viz. Lactobacillus plantarum (LP) and Bacillus subtilis (BS), each mixed with oligofructose as prebiotic, synthetic pesticide containing Lambda-cyhalothrin + dimethoate and a non-synbiotic treatmen...
Studies on interactions between plants and belowground organisms, or between plants and aboveground organisms, are numerous and highlight their importance in understanding ecosystem functioning. However, these two compartments are rarely studied together, despite the direct link formed by the plant itself. Soil organisms can influence interactions ...

The scarcity of freshwater for agriculture in many regions has led to the application of sewage and saline water for irrigation. Irrigation with non-conventional water sources could become a non-harmful process for plant cultivation, and the effects of their use on crops should be monitored in order to develop optimal management strategies. One pos...

Global warming strongly impacts many organisms' development, distribution and population structure. This problem has attracted the attention of many scientists to understand and study its actual effects, especially on insects influenced by environmental temperatures. Aphids are a model for studies of the genetics and physiology of stress. Aphids ar...
Three viral diseases transmitted by aphids can cause significant yield losses in beet, straw cereal and oilseed rape production. For a long time, these crops were protected against yellows by targeting aphids using plant protection products that have recently been banned (neonicotinoid family) or are still authorised, but whose effectiveness may be...
Metarhizium anisopliae (Metschnikoff) Sorokin and Beauveria bassiana (Balsamo) Vuillemin are entomopathogenic fungi commonly used in microbial control of arthropods. In this study, we evaluated the insecticidal potential of six isolates of B. bassiana (BIITAC10.3.3, BIITAC6.2.2, and BIITAC8.1.5) and M. anisopliae (MIITAC11.3.4, MIITAC6.2.2, and MII...

Aphids are valuable models for studying the functional diversity of bacterial symbiosis in insects. In addition to their ancestral obligate nutritional symbiont Buchnera aphidicola , these insects can host a myriad of so-called facultative symbionts. The diversity of these heritable bacterial associates is now well known, and some of the ecological...
Background Aphids often harbor bacterial symbionts that confer resistance to biotic and abiotic stress. Previous studies have primarily examined the direct effects of symbiont infection on parasitoid success but less on aphid population dynamics under indirect parasitic situations, for example when exposed to parasitoid wasp odor. Deciphering this ...
