Interspecific competitions are important mechanisms in structuring ecological communities, including agroecosystems, which different species may share the same food resource. In melons, two major pests coexist time and space, Liriomyza sativae Blanchard (Diptera: Agromyzidae) Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). The former feeds on leaf mesophyll, while latter phloem sap. Theref...

The release rhythm of volatiles is an important physiological characteristic of plants, because the timing of release can affect the function of each particular volatile compound. However, most studies on volatiles release rhythms have been conducted using model plants, rather than crop plants. Here, we analyzed the variations in volatile compounds released from healthy and leafminer (Liriomyza...

Recent studies on plants genetically modified in jasmonic acid (JA) signalling support the hypothesis that the jasmonate family of oxylipins plays an important role in mediating direct and indirect plant defences. However, the interaction of two modes of defence in tritrophic systems is largely unknown. In this study, we examined the preference and performance of a herbivorous leafminer (Liriom...

Wing-motion of hovering small fly Liriomyza sativae was measured using high-speed video and flows of the wings calculated numerically. The fly used high wingbeat frequency (≈265 Hz) and large stroke amplitude (≈182°); therefore, even if its wing-length (R) was small (R ≈ 1.4 mm), the mean velocity of wing reached ≈1.5 m/s, the same as that of an average-size insect (R ≈ 3 mm). But the Reynolds ...

Hydrogenated cardanol derivatives were evaluated as potentially active insecticides/repellent agents against insect pests such Liriomyza sativae (Diptera: Agromyzidae) and Bemisia tabaci biotype B (Hemiptera: Aleyrodidae). Benzoylation, acetylation, methylation made on the hydrogenated aromatic ring to synthesize ingredients with potential insecticide action. Nuclear magnetic resonance spectra ...
