“…The diamondback moth, Plutella xylostella , is an example of invasive species that act as a significant universal pest of various crops ( Nakaishi et al, 2018 ). P. xylostella also generates an enzyme that avoids the generation of dietetic isothiocyanates that act as plant defense compounds emitted by the host plant and regulate feeding behavior of diamondback moths female ( Hussain et al, 2019 , 2020 ). Furthermore, P. xylostella has been discovered to be resistant to a wide range of chemical pesticides.…”

Insect pests cause significant agricultural and economic losses to crops worldwide due to their destructive activities. Pesticides are designed to be poisonous and are intentionally released into the environment to combat the menace caused by these noxious pests. To survive, these insects can resist toxic substances introduced by humans in the form of pesticides. According to recent findings, microbes that live in insect as symbionts have recently been found to protect their hosts against toxins. Symbioses that have been formed are between the pests and various microbes, a defensive mechanism against pathogens and pesticides. Insects’ guts provide unique conditions for microbial colonization, and resident bacteria can deliver numerous benefits to their hosts. Insects vary significantly in their reliance on gut microbes for basic functions. Insect digestive tracts are very different in shape and chemical properties, which have a big impact on the structure and composition of the microbial community. Insect gut microbiota has been found to contribute to feeding, parasite and pathogen protection, immune response modulation, and pesticide breakdown. The current review will examine the roles of gut microbiota in pesticide detoxification and the mechanisms behind the development of resistance in insects to various pesticides. To better understand the detoxifying microbiota in agriculturally significant pest insects, we provided comprehensive information regarding the role of gut microbiota in the detoxification of pesticides.

BACKGROUNDMultiple and simultaneous attacks by pathogens and insect pests frequently occur in nature. Plants respond to biotic stresses by activating distinct defense mechanisms, but little is known about how plants cope with multiple stresses. The focus of this study was the combined interaction of fungal infection caused by Leptosphaeria maculans (synonym Plenodomus lingam) and arthropod infestation by the diamondback moth (Plutella xylostella) in oilseed rape (Brassica napus). We hypothesized that infection by the fungal pathogen L. maculans could alter oilseed rape palatability to P. xylostella‐chewing caterpillars. Feeding preference tests were complemented with analyses of defense gene transcription, and levels of glucosinolates (GLSs) and volatile organic compounds (VOCs) in L. maculans‐inoculated and non‐inoculated (control) leaves to determine possible causes of larval choice.RESULTSCaterpillars preferred true leaves to cotyledons, hence true leaves were used for further experiments. True leaves inoculated with L. maculans were more palatable to caterpillars over control leaves during the early stage of infection at 3 days post inoculation (dpi), but this preference disappeared in the later stages of infection at 7 dpi. In parallel, genes involved in the salicylic acid and ethylene pathways were up‐regulated in L. maculans‐inoculated leaves at 3 and 7 dpi; L. maculans increased the level of total aliphatic GLSs, specifically glucobrassicanapin, and decreased the level of glucoiberin at 3 dpi and altered the content of specific VOCs. A group of 55 VOCs with the highest variability between treatments was identified.CONCLUSIONWe suggest that the P. xylostella preference for L. maculans‐inoculated leaves in the early stage of disease development could be caused by the underlying mechanisms leading to changes in metabolic composition. Further research should pinpoint the compounds responsible for driving larval preference and evaluate whether the behavior of the adult moths, i.e. the stage that makes the first choice regarding host plant selection in field conditions, correlates with our results on larval host acceptance. © 2024 Society of Chemical Industry.

“…Efek limbah cair tahu terhadap preferensi oviposisi P. xylostella dapat terjadi secara langsung maupun tidak langsung. Secara langsung, proses preferensi P. xylostella akan dipengaruhi oleh kandungan senyawa primer sebagai nutrisi di dalam tanaman dan senyawa sekunder, seperti aroma (odour) yang dikeluarkan oleh tanaman kubis (Hussain et al, 2020;Long-Liu et al, 2020;Conchou et al, 2019), dan juga stadia perkembangan dari tanaman kubis (Barbosa et al, 2019). Secara tidak langsung, aroma yang dihasilkan dari limbah cair tahu juga dapat memengaruhi preferensi oviposisi P. xylostella.…”

Tofu wastewater containing a high proportion of organic compound may cause various adverse impacts, such as water pollution which bad smell and degrading the aesthetics of the environment. The efforts uses of tofu wastewater is a organic liquid fertilizer. The aims of this study was to determine the effect of tofu wastewater on cabbage growth and preference of Plutella xylostella. The experiment was carried out from April to June 2018, at Ciparanje Experimental Field, Faculty of Agriculture, Universitas Padjadjaran. Randomized block design was used with nine treatment concentration of tofu wastewater consist of control 0%, 12.5%, 25%, 37.5%, 50%, 62.5%, 75%, 87.5%, 100%, and three replication. The result showed that tofu wastewater by 100% could increase the growth of cabbage. The highest female P. xylostella preference.
