English grain aphid, Sitobion avenae (Fabricius) (Hemiptera: Aphididae), is an important pest of wheat (Triticumaestivum L.), and is usually controlled by intensive foliar sprays of pesticides under field conditions. In order toreduce labour costs and increase the utilization of pesticides, neonicotinoids seed treatment was studied as asimple and accurate control technology for S. avenae. We evaluated the mortality of imidacloprid, acetamiprid,thiamethoxam, clothianidin, nitenpyram and dinotefuran to the English grain aphid by seed dressing methods inthe laboratory, and found that the toxicity with that LC50 of clothianidin (20.97 a.i. g/100 kg seeds) and thiamethoxam(28.84 a.i. g/100 kg seeds) to S. avenae are higher than other neonicotinoids. LC50 values of nitenpyram,imidacloprid and acetamiprid ranged between 120 a.i. g/100 kg seeds and 210 a.i. g/100 kg seeds. Dinotefuran showed the lowest toxicity with LC50 value 565.76 a.i. g/100 kg seeds to English grain aphid. Fieldplot experiments were conducted to investigate the control efficacy of neonicotinoids seed treatment for theaphid, and the effects on growth of wheat. Field observations indicated that clothianidin and thiamethoxamprovided the better control efficacy on the English grain aphid than imidacloprid, and had no influence on wheatseedling emergence. These results showed that seed treatment by neonicotinoids was effective against S. avenaethroughout the growth period, furthermore, thiamethoxam and clothianidin were the effective and safe alternativeoptions for S. avenae management in the crop.

Sex pheromone of the jumping plant bug, Halticus minutus Reuter (Hemiptera: Miridae)

The jumping plant bug, Halticusminutus Reuter, is a pest of sweet potatoes, soybeans and turfgrass in China. Here we present our analysis of the female-produced sex pheromone. These plant bugs release their sex pheromone, consisting hexyl acetate (HA), hexyl butyrate (HB) and (E)-4-oxo-2-hexenal (4-OHE), at night. These three components, tested individually, elicited strong antennal responses. Field tests indicated that a ternary blend of HA, HB and 4-OHE, at ratios of 1:16:10, effectively attractedmale H. minutus. Our dose-response analysis showed optimal male capture at the trap dose of 13.5mg/trap. Higher trap doses did not improve capture rates. Higher ratios of HB in the pheromone mix led to substantially reduced captures, fromwhich we infer that HBmay function as an alarm pheromone or defensive secretion. Pipette tips were used as long-term lures, and whose longevities were evaluated. Results showed effective duration of pipette tip lures were N5 weeks. Thus, we suggest that the pheromone-baited traps are economically viable tools for long-term monitoring and trapping of jumping plant bugs.
