Abstract

The cassava lacebug, Vatiga illudens (Drake) (Hemiptera: Tingidae), is a pest that feeds on cassava foliage, significantly reducing the yield of tuberous roots. Recently introduced to Asia, this invasive exotic pest has been reported only in Indonesia, where it poses a serious threat to cassava cultivation. This study aimed to determine the resistance levels of ten Indonesian cassava cultivars to V. illudens. The leaf nutritional profile (proximate content), as well as phenol and hydrogen cyanide (HCN) content, were analyzed as potential factors affecting the biological parameters of V. illudens. Results from the choice test revealed that V. illudens adults exhibited a clear preference for certain cultivars, with the highest numbers observed on Gajah (10.00 individuals), Adira 1 (5.60 individuals), and Mentega (5.20 individuals). In contrast, adult numbers on the remaining cultivars were lower, ranging from 2.40 to 3.60 individuals. In the no-choice antibiosis test, the nymphal developmental period (from first instar to adult) ranged from 11.70 to 20.40 days, while adult longevity varied from 9.05 to 16.30 days. Leaf HCN content was the only chemical property found to be associated with the degree of resistance in cassava cultivars, with low-HCN cultivars like Gajah (9.66 mg/g) and Mentega (11.26 mg/g) being more preferred by V. illudens. The insect also exhibited faster development and extended adult longevity on these cultivars, leading to increased population growth. These findings are expected to provide valuable information for the management of V. illudens.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
