Abstract

Online shopping is quite a new thing these days, although some people are still unaware of it. Although everyone uses the word "shopping" regularly, Internet shopping is becoming more and more popular these days. When everyone goes to shopping, some people get what they need, while others buy more. It means that it can satisfy an internal objective. If someone wants to talk to a close friend or relative, they can send them messages without any charges, search anything on Google, locate someone, express their love towards them through gifts, etc. This is an advantage of modern technology. This study examines consumers who purchase electronic goods online or offline. Even though traditional markets are shrinking due to the expansion of the Internet, some customers still prefer to shop offline. Since it is difficult to buy electronic products online, most people decide to buy offline, while some people prefer to buy online. The overall study aims to determine the percentage of consumers who prefer to purchase electronic items through both offline and online mediums.The research analyses what customers' preferences, decision-making processes and behavior vary between online and offline shopping scenarios. Through the analysis of the relationship between traditional offline merchants and online shopping, this study seeks to identify consumer decision-making variables in the complex market of Ahmedabad

Abstract

A field-collected laboratory population of Chrysoperla carnea, a polyphagous predator important in integrated pest management, was subjected to flonicamid selection pressure for three generations using a micro-droplet topical bioassay. Following selection, the flonicamid-selected strain exhibited 6.83-fold resistance (LC50 = 260,730 ppm; 95% FL = 148,090–1,561,600 ppm) compared with the unselected strain (LC50 = 38,122 ppm; 95% FL = 23,259–138,440 ppm). Reciprocal crosses between resistant and susceptible parents produced overlapping 95% FLs, demonstrating autosomal inheritance with no detectable maternal or sex-linked effects. Dominance metrics indicated incomplete to partial dominance of resistance (DLC = 0.60 for F1; DLC = 0.55 for F2). Effective dominance estimates at four diagnostic doses (27,875; 62,500; 125,000; 272,000 ppm) yielded ED values of 0.53, 0.79, 0.91, and 0.88, respectively, showing increased dominance at higher doses. Chi-square goodness-of-fit tests rejected the null hypothesis of monogenic inheritance (p < 0.05), confirming a polygenic resistance model. Cross-resistance bioassays further revealed substantial co-selection effects, with resistance ratios of 24.35-fold for acetamiprid, 23.58-fold for triazophos, and 15.17-fold for deltamethrin, comparing initial and final LC50 values that showed non-overlapping 95% FLs. These results indicate that flonicamid resistance in C. carnea is a polygenic, autosomal, and incompletely to partially dominant trait. The findings provide genetic foresight for incorporating resistant predator populations into insecticide-compatible IPM programs and highlight the importance of mode-of-action-based chemical rotation to mitigate resistance co-selection in beneficial predator populations.
