“…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). In the present study, combinations of CB 100 + CIP 5…”

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.

Precise identification of exotic whiteflies is a prerequisite to curb the invasive potential on to a new geographical location and to evolve effective management strategies. Conventionally, whitefly taxonomy is based on the description of the fourth‐instar nymph or puparium, however, in the current investigation egg to adult morphology along with morphometrics of rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin was critically analyzed and various morphological characteristics were illustrated. The morphometric analysis revealed that in the immature life stages of the pest, the length: width ratio decreased with each successive life stage, such as the egg, first, second, third, and fourth instar (2.472 ± 0.071, 1.913 ± 0.020, 1.550 ± 0.045, 1.297 ± 0.034, and 1.174 ± 0.058 mm), respectively. Across different nymphal instars, the shape of lingula was greatly modified from tongue‐like to triangle‐shaped. The number and distribution of compound pores also vary among the different nymphal stages. The ultra‐structures of the antenna through electron‐microscopy depicted finer details of sensory cones. The modulation in the shape and the structural arrangement of microtrichia on the plate was illustrated. The study indicated accurate diagnosis of various stages of RSW for effective interception of goods at quarantine stations and thus preventing the entry of exotic pests into the country.

“…High temperature and high humidity have a positive correlation with the whitefly population 47 . RSW complete its life cycle in 37.6 days at 20.05–23.9 °C, 67–71.5% RH and 59 days at 25–30 °C, 70–85% RH 24,48 . The availability of host plants in larger areas throughout the year and prevailing suitable weather, this highly destructive insect pest could able to complete 6–10 generations per year and may pose a serious threat to the cultivation of coconut and other horticultural crops under future climatic change.…”

BACKGROUND Rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin, is a highly polyphagous invasive pest native to Central America. The occurrence of A. rugioperculatus in the Oriental region was first reported from Pollachi, Tamil Nadu, India in 2017. This pest is widely distributed in India, causing severe economic damage to coconut and other horticultural crops. It is a recent invasion in India and information on its potential distribution is lacking. Thus, in the present study we used the latest Coupled Model Intercomparison Project phase 6 (CMIP6) dataset through Maximum Entropy species distribution modelling (version 3.4.1, MaxEnt) to determine the potential distribution of RSW in present and future climate change scenarios in 2050 and 2070 under Shared Socioeconomic Pathway (SSP) 126 and SSP585 emission scenarios. The performance of the model was evaluated using the area under the curve (AUC), true skill statistics (TSS) and the continuous Boyce index (CBI). RESULTS The MaxEnt model performed well and predicted the potential distribution of A. rugioperculatus with high‐accuracy AUC values of 0.991 and 0.989, TSS values of 0.891 and 0.842, and CBI values of 0.972 and 0.934 for training and testing, respectively. Jackknife analysis revealed that A. rugioperculatus distribution was mostly influenced by temperature‐based bioclimatic variables contributing 62.1% of the suitability, with precipitation variables contributing the remainder. The most important bioclimatic variables for RSW distribution were annual mean temperature (Bio 1, 28.9%) followed by mean diurnal range (Bio 2, 19.5%) and annual precipitation (Bio 12, 19.1). Potential suitable areas for RSW establishment were mostly found in all coastal and southern states of India. A. rugioperculatus prefers a warm and humid climate, indicating that the tropics, subtropics and temperate regions are ideal for its spread and invasion. Our results highlighted that the suitable habitat area for A. rugioperculatus is predicted to increase and highest probability of invasion and spread in 2050 and 2070 under future climate change scenarios of SSP126 and SSP585 compared to present climatic conditions. CONCLUSIONS This is the first study to use the latest CMIP6 models and it predicts the potential distribution of RSW in India under present and future climate change scenarios. The implementation of strict domestic quarantine measures may prevent the spread and damage of RSW to noncoastal regions of India. The results of the current study should help in timely monitoring and surveillance of RSW and to formulate integrated pest management strategies at the national level to restrict its spread, invasion and damage to new areas. © 2022 Society of Chemical Industry.
