Rhamnolipids (RLs), biosurfactants produced by Pseudomonas aeruginosa, have gained attention for their potential role in pest management. This study investigated the efficacy of RLs controlling two-spotted spider mite (Tetranychus urticae) and whitefly (Trialeurodes vaporariorum), as well a novel non-commercial essential oil-based product, Petir Kilat, on cucumber tomato plants within controlled greenhouse environment.

The Aphis gossypii is a major threat of cotton worldwide due to its short life cycle and rapid reproduction. Chemical control the primary method used manage aphid, which has significant environmental impacts. Therefore, prioritizing eco-friendly alternatives essential for managing aphid. ladybird, Hippodamia variegata , predominant predator Its performance in plantation directly linked chemical communication, where volatile compounds emitted from aphid-infested plants play important roles successful predation. Here, we comprehensively studied interaction between pest, natural enemy host by analyzing profiles using gas chromatography-mass spectrometry (GC-MS). We then utilized identified electrophysiological recording (EAG) behavioral assays. Through tests, initially demonstrated clear preference both larvae adults H. plants. Subsequently, 13 compounds, namely α-pinene, cis -3-hexenyl acetate, 4-ethyl-1-octyn-3-ol, β-ocimene, dodecane, E-β-farnesene, decanal, methyl salicylate, β-caryophyllene, α-humulene, farnesol, DMNT, TMTT were All these electrophysiologically active induced detectable EAG responses adults. Y-tube olfactometer assays indicated that, with few exceptions larvae, all chemicals attractive particularly at highest tested concentration (100 mg/ml). outcomes this study establish practical foundation developing attractants open avenues potential advancements aphid management strategies understanding details communication tritrophic level.

Aquafeed production is a fast-growing industry, seeking novel, cost-efficient raw materials to diversify traditional ingredients like fish meal and oil. Insects, particularly BSF larvae, convert by-products waste into value-added biomass. In this study, co-products from two major fish-transforming industries in the Iberian Peninsula, i.e., tuna heads (THs) codfish frames (CFs), hydrolysates of THs CFs, TH oils, were supplied larvae improve their profile n-3 fatty acids (FAs), namely EPA DHA, protein/amino acid content. By testing replacement levels control diet with co-products, we evaluated amount FA that could be added larval tissues. The results showed high hydrolysed negatively impacted survival. addition, parameters such as moisture, protein content, viscosity substrate affected bioconversion rates. Nevertheless, fed these diets contained lysine (5.8–8.4%, dry weight (DW)), methionine (1.5–2.4%, DW), (14.4% DW: 6.7% DHA 7.1%). These findings suggest can effectively nutrient-rich biomass for aquafeeds, supporting diversification material sources promoting circular bioeconomy.

Stored products are significantly affected by certain well-known stored grain pests, with Sitophilus oryzae L. (Coleoptera: Curculionidae) being one of the most destructive pests products. It is a primary pest that causes substantial quantitative and qualitative losses. The present study was conducted to investigate insecticidal efficacy different plant extracts from four commonly grown plants in Pakistan: ginger (Zingiber officinale), neem (Azadirachta indica), clove (Syzygium aromaticum), tobacco (Nicotiana tabacum) against S. infesting wheat. Crude these were applied wheat at various dose rates (20, 40, 60, 80 mg). Adults introduced treated observed for mortality, repellency, damage. results indicated maximum mortality (99.17%) recorded due application crude extract Z. officinale, while minimum (67.50%) N. tabacum an mg rate after 10-day exposure interval. damage (0.19%) rate, (0.04%) officinale rate. also exhibited repellent effect on (95.77%). This concluded emerged as potent, readily available biopesticide oryzae, surpassing current alternatives near-eradication efficacy, minimal damage, proactive effect, paving way sustainable eco-friendly management.
