“…In the present study, the intrinsic rate of increase (rm) was observed to be higher on Bt 88 and lower on the non-Bt cultivar (Table 3). This finding was correlated by Samih et al (2014), who found 0.1010, 0.1286 females/female/day on cotton and rapeseed; Musa and Ren (2015) who reported 0.1875 females/female/day on soybean; Calvitti and Remotti (1998) who ranged between 0.0844 to 0.1121 females/female/day for B. argentifolii on six cotton cultivars; Kakimoto et al (2007) who observed 0.168, 0.153, 0.143 and 0.110 females/female/day on eggplant, cucumber, sweet pepper, and tomato; Ahmad and Rizvi (2014) who founded 0.190, 0.114, 0.147 and 0.136 females/female/day on eggplant, chili, tomato, and okra. The population of whitefly was faster growing on Bt cultivars than non-Bt.…”

Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) is a common cotton pest that causes massive economic losses yearly, directly or indirectly. This study aimed to investigate the effects of Bt cotton on the biological and life table parameters of B. tabaci under controlled conditions.The incubation, nymphal, and pupal periods were recorded as shortest on Bt and longest on non-Bt cultivars. It completed immature stages within 27.8, 28.2, and 28.6 days on Bt, whereas it took 30.4 days on the non-Bt cultivars. Adult longevity increased in Bt cultivars while decreasing innon-Bt cultivars. The male lived for a shorter duration and was smaller than the female. Pre-oviposition was higher in non-Bt cultivars and lowered in Bt cultivars. Bt cultivars had longer oviposition periods than non-Bt cultivars. Fecundity was relatively higher on Bt (57.5, 55.1, and54.2 eggs/female) but reduced on non-Bt (48.2 eggs/female). The life table parameters were also modified using different cotton cultivars. Age-survivorship declined with age, and the highest mortality was recorded at the egg stage, with non-Bt having a longer life span than Bt cultivars. In the egg stages, life expectancy was similarly greater. The net reproductive rate (RO) was recorded as the highest, and the intrinsic rate of increase (rm) was the lowest on Bt cultivars. Non-Bt cultivars had the highest finite rate of increase, mean generation time, and population doubling time, while Bt cultivars had the lowest. The experimental findings showed that Bt was slightly more suitable for developing B. tabaci than non-Bt cultivars.

“…And also per cent egg hatchability of RSW was reduced in guava followed by banana, coconut and sapota. This might be due to the food quality, food quantity, temperature, host plants and biotype influence the developmental rate and reproduction of the host insect (Samih et al, 2014). Host plant characteristics include physical (waxy covering, fibrous lamina, trichomes on foliage) and biochemical substances that influence the growth period of the rugosa whitefly (Pradhan et al, 2020).…”

The rugose spiralling whitefly is an invasive sucking pest on horticultural crops found in India. Elimination of endomicrobial communities harboured in hosts through antibiotic treatments adversely affects the fitness parameters of rugose spiralling whitefly. Keeping this in view, the present study aimed to evaluate the ovicidal action of antibiotics against rugose spiralling whiteflies reared on four host plants. Antibiotics with varied modes of action were erythromycin, ciprofloxacin, carbenicillin and cefotaxime and were applied to coconut, banana, sapota and guava leaves for whitefly oviposition. Antibiotic treatment, carbenicillin 100 μg/mL + ciprofloxazin 5 μg/mL significantly (p<0.05) reduced the oviposition and % egg hatchability of whiteflies reared in coconut (13 eggs/spiral and 61.54%), banana (15 eggs/spiral and 60.00%), sapota (15 eggs/spiral and 66.67%) and guava (16 eggs/spiral and 56.25%). The reduction in the number of eggs per spiral and hatchability percentage proved that antibiotic treatments significantly (P<0.05) reduced rugose spiralling whitefly fecundity. Antibiotic material affects the fitness parameters of whitefly by disrupting the endomicrobial communities associated with whitefly. Antibacterial materials have a potential plant protection role in the management of whiteflies by reducing population growth.

“…The higher values of the population parameters except mean generation time exhibit a large population size (Goundoudaki et al 2003). The significant differences in these population parameters were demonstrated by two biotypes of B. tabaci reared on G. hirsutum L. and Brassica napus L. (Samih et al 2014). Musa and Ren (2005) reported that based on population parameters, rapeseed and cotton offered slow development of B. tabaci as compared to soybean.…”

“…The most advanced form of life table is the age-stage two-sex life table developed by Chi (1988) and Chi and Liu (1985) which considers stage differentiation and offers a nearly appropriate estimate of the future population in varying conditions. Unfortunately, the use of the age-stage two-sex life table remained underemphasized to study the biology of sucking pests due to inappropriate handling of a large amount and misinterpretation of data (Samih et al 2014).…”

The sucking pests, especially whitefly, have damaged various fields and fruit crops across the globe. The study of life-history is of prime importance to monitor the dynamics for preference of a species to its host. This study tested the prevalence and preference of a whitefly species, Bemisia tabaci (Gennadius) B biotype (Hemiptera: Aleyrodidae) on tomato, cotton, pepper, and okra as hosts using age-stage two-sex life table. Results revealed the highest pre-adult developmental duration, survival rate, and fecundity on tomato while the lowest values on okra. Population parameters such as the net reproductive rate (R0), intrinsic rate of increase (r), and finite rate of increase (λ) were demonstrated longer on cotton and tomato compared to much lower R0, r, and λ on pepper and okra. Okra responded significantly differently in the case of the mean generation time, T among all tested genotypes. These findings suggest the possibility of summer vegetables as more favorable hosts for B. tabaci. © 2021 Friends Science Publishers
