Extreme gastronomy tourism can usually be defined in many ways, it because of the cooking methods or interesting ingredients. Some countries like China and Thailand have unique gastronomy, so does city Tomohon Indonesia. In fact, has turned into one world’s threads since extreme ingredients were part pandemic’ causes. Not to mention, most them are taken from wildlife where we not predict whether they been vaccinated yet. This trouble will eventually cause all over world would start another lockdown which also affect due lack mobility, on other hand factors why increased recently. short, concluded that impact pandemic stop activity affecting a country’s economy too. journal is reviewing journals literature Google Scholar, Nature Pubmed.

Beauveria bassiana PfBb is a new strain with high host specificity to the target pest Phauda flammans. We conducted series of experiments optimize biphasic fermentation system B. by screening medium compositions and environmental conditions in both liquid solid fermentations. In fermentation, glucose yeast extract C:N ratio 17:1 were optimal carbon nitrogen sources, respectively, for mycelium growth blastospore production, an inoculation concentration 1 × 108/mL inoculum content 50 mL conidial suspension, at 180 rpm/min rotation speed, pH 7 26 °C, favored growth. However, additional trace elements did not significantly improve fermentation. wheat bran chaff 8:2 identified as best substrates that facilitated sporulation germination, 20% content, 50% water 3-day darkness had highest conidia yield. The resulting conidia, stored -20, 4, 20 °C one year, change prolonged storage duration, germination was higher -20 4 °C. Moreover, year maintained its validity virulence, which toxic all instar larvae P. Our results provide essential support commercial production PfBb-based biopesticides.

This study aimed to explore the physiological and biochemical mechanisms of interaction between N. grossedentata A. nigripes. First, specimens were categorized into low- (6.16% ± 0.66%), medium- (9.23% 1.19%), high-content groups (21.23% 1.23%) based on initial dihydromyricetin concentration in grossedentata. Subsequently, we assessed variations total flavonoids, dihydromyricetin, myricitrin, myricetin plants 24, 48, 72 h post-feeding. Concurrently, analyzed impact plant leaf consumption detoxifying [glutathione S-transferase (GST), carboxylesterase (CarE), acetylcholinesterase (AchE), cytochrome P450 (CYP450)] protective enzyme [superoxide dismutase (SOD), peroxidase (POD) catalase (CAT)] activities nigripes, along with its metabolic processes. The results demonstrated that enhanced secondary metabolites, particularly as a defensive response insect-induced stress. nigripes utilized detoxification systems mitigate effects high flavonoid levels host plant, particular emphasis roles enzymes (GST, AchE, CYP450, CarE) metabolism, which showed significant correlation (p < 0.01) exhibiting coefficients 0.689, 0.633, 0.579, 0.561, respectively. Additionally, key flavonoids observed accumulate different degrees during digestion metabolism insects. These findings lay theoretical foundation for further exploration molecular adaptation flavonoid-rich inform development novel pest control strategies selection resistant varieties.

Leafcutter ants (Atta spp.) are one of the mos t economically harmful pests in agriculture, considered dominant Neotropics and South America. Mature colonies A. mexicana have a great economic impact on Mexico’s agriculture. Microbial agents form biopesticides an effective component integrated pest management (IPM) strategies may present better alternative to synthetic insecticides. Among fungi most used as biological insecticides there Beauveria bassiana Metarhizium anisopliae. The objective this research was evaluate effect entomopathogenic B. M. anisopliae commercial origin native strain from México (MA-Bb1) adults Atta under controlled conditions. In bioassay, five formulations control group were tested (B. MA-Bb1, MA-Bb1+ Diatomin®, bassiana®, anisopliae®, Tween 80 (0.01%). Diatomin® biopreparation induced highest mortality (100%) four-week-old mexicana, followed by bassiana® biopreparations, which caused 83.33%, 73.98%, 68.70%, respectively. Treatments containing efficient controlling achieved with fungus presented total death rate 96 h post infection, contrast (Tween 80), attained lowest speed investigation.

Neem, a biopesticide, offers safer alternative to the synthetic insecticides commonly used in mulberry cultivation, which can harm silkworms. This study aimed investigate effects of Thai neem seed extract on all instar larvae polyvoltine hybrid silkworm, Bombyx mori L., Dok Bua strains, focusing mortality rate and activities esterase (EST) glutathione S-transferases (GST) enzymes. Acute toxicity was assessed using leaf-dipping method. Results showed that tended be higher younger instars than older ones. The first exhibited highest at 94%, whereas LC50 third 5.23 mg L−1 72 h. trend aligns with EST GST, were evaluated whole bodies midgut tissue fifth larvae. As concentration increased, activity decreased while GST increased both These findings highlight is toxic larvae, playing crucial role detoxification, particularly body silkworm.

Abstract BACKGROUND Traditional chemical pesticides are easily lost by surface runoff and only small quantities reach the target, thus causing serious environmental pollution. In this work, dinotefuran@zeolitic imidazolate framework‐8@polydopamine@zein (DNF@ZIF‐8@PDA@zein), was constructed to deliver DNF with pH enzyme double response of release, thereby achieving targeted release efficient long‐term pest control. RESULTS DNF@ZIF‐8@PDA@zein synthesized three hydrated diameters (249.73 ± 9.99 nm, 142.94 5.63 nm 75.16 4.66 respectively). The from after 28 h significantly higher at 5.0 (89.22 7.18%) compared that 8 (81.8 6.11%). Protease‐assisted notably than without protease (pH 5: 89.22 5.55% versus 27.19 3.22%; 8: 81.8 6.11% 25.39 3.87%). stimuli‐responsive increased decreased particle size due pore size, reduced binding forces (i.e., weaker π–π stacking, hydrogen bonding, Zn–N covalent bonding), shortening diffusion path, leading faster disintegration drug release. Additionally, anti‐photolysis ability 3.2 times pure DNF. insecticidal activity improved smaller nanoparticles rate greater inhibition detoxification more zinc ion (Zn 2+ ) dissolution. CONCLUSION dual‐responsive as well increase nanoparticle showing effective management in potential application prospects sustainable agriculture. © 2024 Society Chemical Industry.
