“…Leafhoppers were collected from the leafy vegetable farms of South Rudbar-e-Jonoob located 320 km south of Kerman province using an insect sweep net and were transferred to greenhouse under cold conditions using an ice box. Subsequently, adult insects from two genera, Circulifer and Austroagallia, were separated using external morphology [21][22][23][24][25] and caged on healthy parsley seedlings using an aspirator and transparent cylinder sealed at one end with cotton mesh. Leafhoppers were kept under insect-proof conditions in greenhouse at ~ 25 ºC.…”

This study investigates the transmission potential of parsley yellow leaf curl virus (PYLCV; family Geminiviridae) by Austroagallia sp. leafhopper commonly found in vegetable farms in Kerman province, Iran. Accordingly, following two days of acquisition access period, nymphs from the non-viruliferous colony of Austroagallia sp. successfully transmitted the virus from PYLCV infected parsley to healthy seedlings after seven days from the start of feeding. On the basis of male genitalia morphology, the species of the leafhopper, was identi ed as A. sinuata. To our knowledge, this is the rst report of a plant virus transmission by a species of Austroagallia in the world.

Background The susceptibility of pests and natural enemies to conventional insecticides is a critical element in judging the success of integrated pest management programs implementing biological control as a tactic. In this study, the susceptibility of the cotton leafworm Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) to an organophosphorus insecticide (chlorpyrifos) and the entomopathogenic fungus Beauveria bassiana was evaluated through field applications during two successive sugar beet seasons. The populations of the coccinellid, chrysopid, and formicid predators were estimated to indicate pesticide risk assessment strategy. The root and sugar yields were compared during the whole experiment to emphasize the impact of both control strategies on the pre-harvest loss in this strategic crop. Results Results indicated that over the course of the two seasons of the investigation, chlorpyrifos significantly reduced the population density of S. littoralis and its associated predators. It showed a detrimental effect on S. littoralis larval population than untreated areas, causing an overall reduction of 97 and 92% during the 1st and 2nd seasons, respectively. The biopesticide based on entomopathogenic fungus Beauveria bassiana caused an overall reduction of S. littoralis, reaching 96 and 65% during the 1st and 2nd seasons, respectively. Meanwhile, B. bassiana slightly affects the population of predators compared to insecticide-free areas, so it was recommended for application in sugar beet fields without providing considerable risk to the associated insect predators. The sugar beetroot production and its sugar content increased significantly in both treatments during the two growing seasons compared to non-treated plots. Conclusion Chlorpyrifos is not recommended for pest control; instead, B. bassiana is considered an effective biopesticide in the Egyptian sugar beet fields infested with S. littoralis as part of an integrated pest management program. Their effect was direct through reducing pest population and indirectly increasing the sugar beetroot production and increasing its total sugar content. Hence, both the sugar beetroot quality and quantity were improved favoring the microbial agent over the chemical insecticide in application for mitigating the chemical hazards toward the associated predators.
