... correlated with DAP and whitefly on both USDA accessions and local varieties. Maximum and minimum temperatures, rainfall and wind velocity were negative and non-significantly correlated while, % relative humidity (%R.H) was found non-significantly and positively correlated both with USDA accessions and local varieties. On overall basis, during the course of the season, lowest number of jassid/leaf was recorded on USG-12-8 (1.7) followed by USG-12-44 (3.2) and...

Recent advances in geminivirus detection and future perspectives the last two decades, whitefly-transmitted geminiviruses have emerged as serious pathogens of several agricultural and horticultural crops (like tomato, chillies, cotton, pulses, papaya, cucurbits, okra etc.) causing enormous losses in the tropics, which provide ideal conditions for the perpetuation of viruses and the insect-vector. Despite concerted efforts to contain begomoviruses and their vectors, menacing disease epidemics caused by newly emerging or r...

Evaluation of insecticidal schedules for the management of insect pests of potato population of aphids, whitefly and epilachna beetle was observed in the treatment T which received soil application of phorate followed by spraying of chlorpyriphos,imadicloprid and cartap hydrochloride, respectively at 40, 55 and 70 DAP than other treatments. Maximum yield of healty potato tuber was recorded in the plot treated with chlorpyriphos before planting and foliar spray of acephate, imadichloprid and chlorpyriphos + cypermethrin at 40, 55 and 70 D...

Virus- vector relationship of yellow vein disease of calendula and the whitefly
...ap inoculation. A single whitefly could transmit the virus and showed 20.55% infection and fifteen whiteflies were required for 100 percent transmission. The minimum acquisition access feeding period and minimum inoculation access feeding period for the present virus were 10min and 30min, respectively. Acquisition access feeding period and inoculation access feeding period was 100 percent at 6hr and 3 hr respectively. A pre-acquisition access feeding period of...

Occurrence of potato pests in different dates of planting in Gangetic plains of West Bengal, India
...nfestation. However, the whitefly infestation was found lower in second and third plantings (at 4th week of November and 1st week of December). The infestation of soil pests such as molecricket, cutworm and potato tuber moth were found minimum in crops of 1st date of sowing resulted in producing highest number of healthy tubers. The rat damage was not so influenced by different dates of planting. But, the total tuber yield was obtained maximum in second date (...

Efficacy of different insecticidal treatment schedules against aphid and whitefly on brinjal
...edules against aphid and whitefly on brinjal was studied by conducting two field experiments at 'Adisaptagram Block Seed Farm, Hooghly, West Bengal, India in two consecutive kharif seasons i.e., 2010 and 2011. The experiment was laid in RBD with seven treatment schedules and three replications. Among all the treatments soil application of phorate at transplanting, followed by foliar spray with acephate, thiodicarb and Bacillus thuringiensis var. kurstaki at 50...

...liar application against whitefly, Bemisia tabaci (Gennadius). Imidacloprid 17.8 SL @ 50 g a.i./ha, was found superior against whiteflies among other treatments, received lowest number of whitefly population (1.55/plant) and offered maximum reduction of whiteflies (83.15%) as well as highest marketable fruit yield (146.50 q/ha). However, imidacloprid at lower doses showed nearly similar results. The other neonicotinoid, thia...

...en lacewings. Similarly, whitefly parasitism recorded in the Confidor and Jozer plots was very close to that of control plots for both post-treatment observations. Based on these findings, Confidor and Jozer are recommended to be considered for their integration in sucking pests’ management strategies on transgenic crops such as Bt cotton.

The results showed that whitefly population was significantly suppressed by both the botanical oils and extracts as compared to the control treatment but in general botanical oils showed significant results as compared to plant extracts. Soybean oil was quite...

A survey of whitefly populations and its parasitism with connection to temperature and relative humidity was conducted in fourteen cotton growing districts of Sindh province (southern Pakistan) for 2012 and 2013 seasons. There was a significant difference in

...s, a single viruliferous whitefly had the capacity to transmit the virus, but for 100 percent transmission a minimum of five whiteflies per seedling were required. The minimum requirement of AAP was 30 minutes, which was longer than inoculation access period (IAP) of 20 minutes. For 100 percent acquisition and transmission, a minimum of 10 hours was required. The latent period was five to seven hours. The virus persisted in its vector, Bemisia tabaci, upto 10 ...
