“…From India, GWF was first recorded from Nilgiri hills of Tamilnadu, southern state of India 10 and successively has been reported in other parts of the country 11 – 14 . The increase in area under protected cultivation and climate change in the Uttarakhand states of Indian Himalayan region are critical factors in vulnerability to introduction, invasion, and emergence of GWF in new areas.…”

The Greenhouse whitefly (GWF), Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae), is a destructive pest that affects protected cultivation worldwide. The Indian Himalayan region is particularly vulnerable to GWF introduction, invasion, and spread due to the expansion of protected cultivation and climate change. In this study, we collected 32 naturally occurring GWF populations, mainly from the Uttarakhand state in the Indian Himalayan region, to investigate the distribution pattern and genetic diversity of T. vaporariorum. Our sampling was representative of the region's vegetation diversity and geographical location, and we collected samples from multiple sites within each locality to account for local variations. The mtCOI gene was used to accurately detect and identify GWF and to sequence haplotypes prevalent in the Uttarakhand state. The maximum likelihood method used for phylogenetic studies revealed that all 32 whitefly samples in this study belonged to T. vaporariorum and were prevalent in all the collected localities. Our population genetic study using mtCOI showed variation within T. vaporariorum populations, with 20 distinct haplotypes present. Notably, haplotype 2 (H2) was the most dominant haplotype among the sampled populations. These results provide fundamental knowledge for understanding the geographical distribution and ecology of T. vaporariorum in the Uttarakhand state of the Indian Himalayan region. The discovery of geospatial and genetic diversity of GWF in the Himalayan region underscores the importance of pest alertness, research prioritization, and the development of sustainable management strategies to protect crops.

“…Esta estrategia permite no sólo eliminar las poblaciones de adultos que pudieran representar un riesgo en la trasmisión de virosis, sino también prevenir la emergencia de nuevos adultos que pudieran formar nuevas generaciones dentro del cultivo. Varios estudios han documentado la bondad de esta estrategia en la supresión poblacional de B. tabaci y disminución de virosis asociada (Chavan et al, 2013;Martínez-Tomás et al, 2015;Kashyap et al, 2016;Santos et al, 2018).…”

Background. The whitefly Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) is a pest that causes significant losses in field and greenhouse crops worldwide. Objective. To evaluate the incorporation of biorational and chemical insecticides on the population density of whitefly Bemisia tabaci, fruit yield and fruit quality in tomato. Methodology. Three pest management treatments were included: Biorational (botanical insecticides and insect growth regulators), Biorational-Intermediate (botanical insecticide and chemical insecticides) and Conventional (conventional chemical insecticides). Results. Overall, the population density of B. tabaci was low from the time when the pest-exclusion floating net was removed to the sampling periods 61 to 78 days after transplant (dat). However from 92 to 108 dat, the population density of inmature and adults increased dramatically. The treatment Conventional was the most effective to supress the population density of B. tabaci when they were low, but when an increase in population density of B. tabaci ocurred, the treatment Biorational-Intermediate was the most effective. The population density of eggs and nymphs on plant leaves were similar among treatments. The fruit yield and overall the bromatologic characteristics of fruits were not significantly different among treatments. Conclusion. The treatment Biorational-Intermediate would represent a feasible strategy to manage Bemisia tabaci in tomato crops.
