Action Thresholds of Empoasca terminalis (Homoptera: Cicadellidae) on Soybean in South Sulawesi, Indonesia

Probing Behavior of Empoasca vitis (Homoptera: Cicadellidae) on Resistant and Susceptible Cultivars of Tea Plants

Feeding activities of the tea green leafhopper, Empoasca vitis (Gothe) (Homoptera: Cicadellidae), on resistant and susceptible cultivars of tea plants (Camellia sinensis L.) were recorded and analyzed using the direct current electrical penetration graph (EPG) system. Six distinct EPG waveforms characterizing the feeding behavior of the tea green leafhopper, categorized as waveforms A, C, E, S,...

Variation in tolerance and resistance to the leafhopper Empoasca fabae (Hemiptera: Cicadellidae) among potato cultivars: implications for action thresholds.

The potato leafhopper, Empoasca fabae (Harris) (Hemiptera: Cicadellidae), is an emerging pest of potato and insecticide applications to control this insect have increased in recent years. Based on field observations of leafhopper-crop dynamics, however, currently recommended action thresholds seem to be overly conservative. As a result, we initiated two experiments designed to quantify the impa...

Malaria in North Sulawesi, Indonesia

The incidence and impact of malaria in North Sulawesi have declined both in the short term during the 1990s, and over a much longer timespan (though perhaps less continuously) since the end of the colonial period. The improvement already seems to have been well underway before deliberate vector control activities became extensive in the second half of the 1970s, and environmental changes affect...

Two new species of the leafhopper subgenus Empoasca (Empoasca) Walsh (Hemiptera, Cicadellidae, Typhlocybinae, Empoascini) from China

Two new species of the leafhopper subgenus Empoasca (Empoasca) namely, E. (E.) dorsodenticulata Yu & Yang, sp. n. and E. (E.) spiculata Yu & Yang, sp. n. from China are described and illustrated and a key provided for Chinese subgenera of Empoasca.
