Approximately 400 articles covering various aspects of floral morphology and pollinator attraction were reviewed for the present study. The flowers have been reported to exhibit diverse morphologies, which attract floral visitors to them. Balsams are a real group of plants used to evaluate the overall frequency, relative importance, and various unique pollinator evolution processes. Apart from African species, most species in India are predominantly pollinated by bees. The floral morphological variations, including colour, sepal, petal, and spur morphology, are used to attract or pollinate bees, moths, butterflies, and birds. Pale to deep pink flowers with shallow lower sepals and a narrow entrance have been pollinated by butterflies. In contrast, yellow, white, or pale pink, funnel-shaped lower sepals with hood-like dorsal petals and short spurs have been preferred for pollination by bees. Similarly, red or orange flowers with a broad entrance were usually pollinated by birds, whereas moths pollinated funnel-shaped white flowers with long spurs. The outcome of various studies on the floral morphology of <i>Impatiens</i> in relation to pollination has shown that nectar spur features were highly adopted with the type of pollinators visiting the flower.

Leaves were taken from healthy plants and from plants with mild to severe ant infestations, then tested for photosynthetic efficiency and antioxidant activity. During the initial phase of infestation, mutualism between ants and plants was observed, while severe ant infestations strongly reduced photosynthesis, with a major decline in the plant’s ability to use light energy. While mildly infested leaves showed an initial boost in protective antioxidant enzymes, these defences collapsed under severe infestation, leading to oxidative stress and cellular damage. Overall, the study reveals that while a small presence of ants may stimulate plant defences, large ant colonies harm the plant leaves by overwhelming its protective systems.

We expected that the genetic variability between bitter gourd genotypes is responsible for the varying degree of resistance to fruit fly infestation through distinct morpho-chemical traits. Field screenings (preliminary and final) of twenty bitter gourd genotypes revealed significant differences in fruit infestation and maggot density per fruit and identified five resistant (US-6214, Asmita, Meghnad-2, Vivek and Chandramukhi), nine moderately resistant (Noble Katahi, Palee, Contai Bolder, Mohar, PAN-1983, Chottu, Deb-520, Malaypuri and NS-454) and six susceptible genotypes (Karishma, Abhishek, Akash, Krishna Kantedar, Prachi and Pusa Do Mausami). Resistant genotypes exhibited antixenotic traits such as long tubercles, higher tubercle density, thicker pericarp and tougher fruits, and higher concentrations of protein, total sugar, ascorbic acid, tannin, flavonols, total phenols, peroxidase and polyphenol oxidase. These traits were negatively associated with fruit infestation and maggot density, while higher fruit moisture and chlorophyll contents in the susceptible genotypes were positively correlated. Multiple regression models revealed pericarp thickness, fruit toughness, tannin and flavonols accounted for maximum variation in fruit fly infestation among all morpho-chemical factors.
