Considering that the citrus blackfly, Aleurocanthus woglumi Ashby (Hemiptera: Aleyrodidae), is an important citrus pest, the aim of this research was to develop a conventional sampling plan to assess adult populations of this insect in orange orchards. For this, we defined the sampling unit, number of samples, time and the cost of sampling. The third most apical leaf of the branch was the ideal unit to assess citrus blackfly adult densities and the sampling plan consisted of 58 samples. On average, the plan required 55.26 min to complete and costs US$ 1.78. The sampling plan developed here is an accurate, viable and low-cost tool that can be used in integrated pest managemant programs in orange orchards. Our methods can also be applied to study ecological and geographic parameters of this pest.

Leaves of cucumber, bitter gourd and watermelon were observed with virus like yellowing symptoms of interveinal chlorosis. DAS-ELISA and RT-PCR assay were performed to identify the infecting virus. Nucleotide sequence analysis confirmed the association of Cucurbit yellow stunting disorder virus (CYSDV), a Crinivirus belonging to family Closteroviridae. This study documented the prevalence of CYSDV on cucurbitaceous crops for the first time from India.
