Ricania simulans (Walker, 1851) (Hemiptera: Ricaniidae) a new pest for Turkey

Abstract

This study was carried out to determine distribution, host plant and biology of Ricania simulans (Walker) (Hemiptera: Ricaniidae) in Eastern Black Sea Region of Turkey between 2009 and 2011. There is no important plant pest in the Eastern Black Sea Region of Turkey except this species. However, population of R. simulans being harmful in many wild and cultivated plant species in both nymphal and adult stages has been increased since 2009. As a result of this study, it was determined that R. simulans has been widespread on coastal areas of Eastern Black Sea Region of Turkey with an extensive host range including elderberry, bean, kiwifruit, wild blackberries, hydrangea, fig tree, alder, cherry laurel, tea tree and grapevine. Nymphs of the pest emerge in the middle of May and it has 5 nymphal stages, the adults emerge early July and started to lay their eggs in early August, overwinter as eggs and gives one generation in a year.

“…As a result of the study, it was determined that the plant wastes that had the eggs of the pests, and were cleared and destroyed, caused decreases in the nymph population of 86% and 71%, respectively. Ak et al (2015) conducted a study on the spread, density and biology of the pests between 2010 and 2013, and based on the biological results it was determined that cleaning of the areas and the destruction of the eggs and infected plants / branches will reduce the population of the pests in the following year before the nymphs emerge. This is due to the winter period where the pests of the host plants are about to dry.…”

“…Apparently the spread of this species reaches near by the Black Sea coast. Imura (2003) and Ak et al (2015) reported that the nymphs and adults of R. simulans existed in a variety of weed families and on many plants, feeding on stems and fresh shoots by absorbing the plant juice in plants, and the adults causing harm with their egg laying. Studies reported that Scolypopa australis, which belongs to the same family as R. japonica, in Australia and New Zealand, which has similar biological features and exists on kiwis and some other crops, was commonly found in many weed species and was a significant pest to kiwis; and it was also reported that broad-spectrum insecticides were used against this pest (Logan et al 2002;Charles et al 2004).…”

“…The results in 2014 and 2015 showed the increasing trend for the abundance for the Trabzon city and towns. Ak et al (2015) noted that the most abundant area for the Orosanga specimens is Kemalpaşa. Our results indicated that the hatchling time of the eggs varied yearly and changed from the first week to the fourth week of May and our findings correlated with the results of Ak et al (2015).…”

Ak et al (2015) stated that hatchling time of eggs was the last week of May in 2009 and 2011, but they found that in 2010 the hatchling time was the second week of May.…”

The Weed Flora of Turkish Tea Plantations

“…Tea plants grown in Turkey have recently been significantly affected by both insects (Ricania simulans Walker) (Ak et al, 2015) and weeds. Weeds may significantly reduce yield and impair crop quality, resulting in financial losses to the farmers (Kavaliauskaitė and Bobinas, 2006).…”
