Abstract

Abstract. Puspitarini RD, Fernando I, Setiawan Y, Anggraini D, Rizqi HA. 2021. Short Communication: First record of the cassava lace bug Vatiga illudens (Drake, 1922) (Hemiptera: Heteroptera: Tingidae) from East Java, Indonesia. Biodiversitas 22: 2870-2876. The cassava lace bug, Vatiga illudens (Drake, 1922) (Hemiptera: Heteroptera: Tingidae) is recorded from Indonesia for the first time. This species is found on the abaxial surface of leaves of cassava (Manihot esculenta Crantz, Euphorbiaceae) in several plantations of East Java and heavily infest this plant. Vatiga illudens is native to the Neotropical Region and seems to be the alien species in the Oriental Region. This tingid has already spread over a wide region of East Java, suggesting that the invasion of the lace bug endangers the other regions cultivating cassava.

Occurrence of Cassava Lace Bug <i>Vatiga illudens</i> (Drake, 1922) (Hemiptera: Heteroptera: Tingidae) in Bali, Indonesia

“…This is in line with the research by Cho et al (2020). Morphological identification was carried out following the results of previous publications (Froeschner 1993;Bellon et al 2012;Puspitarini et al 2021). Referring to these morphological characters, the key to identification is the head with a pair of frontal spines (median spine), antennal segment I, and the costal area of the hemelytron.…”

“…The adult female has a single groove along the midline of the ventral side of the apical part of the abdomen. The adult male has no groove at the apical part of the abdomen (Figure 6), the morphological character was compared with previously report by Puspitarini et al (2021). Male insects have a distinctive part like nails (claws) at the end of their abdomen (Figure 6B), while females do not have them (Figure 6A).…”

“…Currently, CLB is already in Indonesia (East Java). In East Java CLB was discovered in Malang, Pasuruan, Blitar, Mojokerto, and Probolinggo, according to the findings of Puspitarini et al (2021). In addition, the distribution of CLB Bali has not been reported.…”

“…At the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, Udayana University, insect samples were prepared for morphological identification under the microscope Nikon smz25. The characterisation of insect morphology was matched with a key determination from a previous publication by Puspitarini et al (2021), and validation of the identification process was conducted by Puspitarini.…”

“…According to Froeschner (1993) the V. illudens has antennal segment I (scape) not longer than head (Figure 4F, 5F). According to Puspitarini et al (2021) costal area of hemelytron with two rows of areolae without apex throughout its length (Figure 4D, 5D). Those keys show that this species is clearly compatible with V. illudens (Figures 3, 4 and 5).…”
