Combined treatments of spinosad and chlorpyrifos-methyl for management of resistant psocid pests (Psocoptera: Liposcelididae) of stored grain

The combined efficacy of spinosad and chlorpyrifos-methyl was determined against four storage psocid pests belonging to genus Liposcelis. This research was undertaken because of the increasing importance of these psocids in stored grain and the problem of finding grain protectants to control resistant strains. Firstly, mortality and reproduction were determined for adults exposed to wheat freshly treated with either spinosad (0.5 and 1 mg kg(-1)) or chlorpyrifos-methyl (2.5, 5 and 10 mg kg(-1)) or combinations of spinosad and chlorpyrifos-methyl at 30 degrees C and 70% RH. There were significant effects of application rate of spinosad and chlorpyrifos-methyl, both individually and in combination, on adult mortality and progeny reduction of all four psocids. Liposcelis bostrychophila Badonnel and L. decolor (Pearman) responded similarly, with incomplete control of adults and progeny at both doses of spinosad but complete control in all chlorpyrifos-methyl and combined treatments. In L. entomophila (Enderlein) and L. paeta Pearman, however, complete control of adults and progeny was only achieved in the combined treatments, with the exception of spinosad 0.5 mg kg(-1) plus chlorpyrifos-methyl 2.5 mg kg(-1) against L. entomophila. Next, combinations of spinosad (0.5 and 1 mg kg(-1)) and chlorpyrifos-methyl (2.5, 5 and 10 mg kg(-1)) in bioassays after 0, 1.5 and 3 months storage of treated wheat were evaluated. The best treatment was 1 mg kg(-1) of spinosad plus 10 mg kg(-1) of chlorpyrifos-methyl, providing up to 3 months of protection against infestations of all four Liposcelis spp. on wheat.

Acute lethal and behavioral sublethal responses of two stored-product psocids to surface insecticides

BACKGROUND: The psocids Liposcelis bostrychophila Badonnel and L. entomophila (Enderlein) (Liposcelididae) are emerging pests of stored products. Although their behavior, particularly their high mobility, may contribute to the reported relatively low efficacy of insecticides against them, studies to investigate this have not been conducted. The present study aimed to assess the label rate efficacy of three commercial insecticides (β‐cyfluthrin, chlorfenapyr and pyrethrins) applied on concrete surfaces against L. bostrychophila and L. entomophila, and also their sublethal effect on the mobility of these species. RESULTS: The synthetic insecticides β‐cyfluthrin and chlorfenapyr showed high short‐term efficacy (LT₉₅≤15 h) against both psocid species, unlike the natural pyrethrins (LT₉₅ ≥ 4 days). Liposcelis bostrychophila was slightly more tolerant (≥1.2×) than L. entomophila to all three insecticides. Behavioral assays with fully sprayed and half‐sprayed concrete arenas indicated that the insecticides reduced the mobility of both species. Pyrethrins seem to elicit weak repellence in L. bostrychophila. CONCLUSION: β‐Cyfluthrin and chlorfenapyr were effective against both psocid species, but not pyrethrins. The mobility of both species does not seem to play a major role in the differential selectivity observed, but the lower mobility of L. bostrychophila may be a contributing factor to its higher insecticide tolerance.

嗜卷书虱和嗜虫书虱酯酶性质的比较研究

对嗜卷书虱Liposcelis bostrychophila和嗜虫书虱L. entomophila羧酸酯酶及乙酰胆碱酯酶(AChE)的生物化学性质进行了初步研究。结果表明:嗜虫书虱的羧酸酯酶活性明显高于嗜卷书虱,嗜卷书虱和嗜虫书虱羧酸酯酶对底物α-NA的Km值分别为0.665 7、0.285 7 mmol/L,Vmax值分别为1.672 2和2.463 1 mmol·(mg·30 min)-1。嗜卷书虱和嗜虫书虱乙酰胆碱酯酶的活性差异不显著,嗜虫书虱略高于嗜卷书虱。通过聚丙烯酰胺凝胶电泳,检测出8条嗜卷书虱、7条嗜虫书虱酯酶同工酶谱带,嗜卷书虱的酶谱分布比嗜虫书虱广。     

磷化氢对3种储粮书虱致死浓度与时间的比较研究

比较测定了磷化氢对嗜卷书虱Liposcelis bostrychophila(Pearman)、嗜虫书虱L.entomophila(Enderlein)和小眼书虱L.paeta(Pearman)等3种储粮书虱的毒力,并研究了在室温条件下磷化氢浓度分别为100、200、300、400和500mL/m3的完全致死时间。结果表明:磷化氢对嗜卷书虱、小眼书虱和嗜虫书虱的LD50值(95%置信限)分别为0.0039(0.0038～0.0042)、0.0804(0.0750～0.0887)和0.0815(0.0815～0.0892)mg/L,嗜虫书虱对磷化氢的耐受力比嗜卷书虱高20多倍。在试验浓度下第7d可全部致死嗜卷书虱,100mL/m3的浓度完全致死小眼书虱和嗜虫书虱则需22d多;200mL/m3完全致死小眼书虱和嗜虫书虱的时间约为19d,300mL/m3浓度完全致死小眼书虱和嗜虫书虱的时间在13d和16d,400mL/m3及以上浓度完全致死小眼书虱在7d以内,完全致死嗜虫书虱仍需13d。500mL/m3的浓度完全致死嗜虫书虱仅缩短到10d。采用磷化氢熏蒸书虱在100～500mL/m3的浓度范围内,提高浓度可以使完全致死书虱的时间明显缩短。
