The occurrence of the leaf miner Asamangulia cuspidata Maulik (Coleoptera: Chrysomelidae: Cassidinae: Hispini) on sugarcane in Coimbatore, Tamil Nadu, India, is reported here with notes on pest biology and parasitoid activity. A minor pest in a few states of subtropical India, the miner was first noticed in May 2014 during routine surveys. Systematic observations in selected experimental and growers' plots revealed low levels of incidence and intensity, the highest mean attack rates being 4.18% on plant basis and 12.41% on leaf basis. Mean mined leaf area showed a high of 4.24 sq. cm and it constituted 1.28% of the total leaf area. Cross-sections of young and mature mines indicated feeding on softer tissues by the solitary grub in the early stages, but extensive mining by the grown-up grub leading to complete drying of the mined area. One apparently new Bracon sp. (Hymenoptera: Braconidae), two Pediobius spp. (Hymenoptera: Eulophidae) and one Eurytoma sp. (Hymenoptera: Eurytomidae) were recovered from the miner. While Bracon sp. contributed 70% to the overall parasitism rate of 39.3%, the remaining parasitoids accounted for 30% with likely hyperparasitism among them. The possible origin of the miner and the role of parasitoids in its natural control at the present study site are also discussed.Keywords

Phenacoccus manihoti Matile-Ferrero (Hemiptera: Coccomorpha: Pseudococcidae), one of the most serious pests of cassava worldwide, was recently introduced to India. Surveillance, early detection and mapping of its distribution in cassava-growing areas are essential to prevent it from spreading further. Several species of mealybug are known to infest cassava in India; their authoritative identification normally requires preparation of slide mounts, which is a highly skilled and time-consuming process. A simple method is described here for screening alcohol-preserved samples of mixed-species infestations for cassava mealybug.Keywords
