“…We were unable to observe the egg in this investigation because it is embedded in the leaf tissue by the female. To see the eggs, one must carefully dissect the leaf at a precise oviposition site (da Silva Wengrat et al 2015). The measurements of the nymphs and adults of V. illudens are presented in Table 2.…”

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.

“…The adults are grayish brown, measuring approximately 3 mm (Froeschner, 1993). The nymphs are whitish and approximately 0.65 to 2.3 mm long depending on the nymphal period (Wengrat et al, 2015). Initially the lace bug populate the undersides of basal and middle leaves of the cassava, but at high population it can infest the apical leaves, being favored by dry periods (Bellotti et al, 2012;Pietrowski et al, 2010).…”

Vatiga manihotae (Drake 1922) (Hemiptera: Tingidae) is an important cassava pest due to the great potential damage and the increasing population in recent years. However, few studies about bioecology and control of the cassava lace bug have been conducted and their results don't provide adequate control strategies. An alternative to maintain the population below economic injury levels is through the adoption of host plant resistance. To improve the understanding about the bioecology and find new sources of resistance in cassava, the biological parameters and demographics of V. manihotae on five cassava genotypes (Santa Helena, MEcu 72, Col 22, Clone 02 and Clone 03) under controlled conditions (25±2°C, 14L/10D) were evaluated. Duration and viability of the stages, the period egg-adult, sex ratio, the pre-oviposition period, fecundity and longevity of male and female was determined, and a fertility life table was prepared. Insects fed on MEcu 72 showed increased nymphal, egg-adult, and pre-oviposition periods and reduced female fecundity and longevity in comparison to the other genotypes. Demographic parameters (Ro, r m , T, DT) showed a significant impact on the growth potential of V. manihotae fed on MEcu 72 indicating that the populations would diminish over time. The combined effect of these parameters indicated that MEcu 72 has resistance on V. manihotae specimens hindering their development.
