	abstract = {Both weevils, Neochetina bruchi (Hustache) and Neochetina eichhorniae Warner feed on water hyacinth plants as a biocontrol agents. Tetranychus urticae Koch infested the plants grown under light and thermostatic controlled aquatic weed green house, and caused repellency of the weevils. Studying some histological structure, of water hyacinth leaves infested with mites, showed increase of the thickness of upper epidermis, number of palisade cell and thickness of leaf petiole, compared with the control and leaves infested with weevils which recorded decrease in the thickness of leaf petiole and increase in lower palisade tissue. The mites infested plants lost chlorophyll, turned brownish and lost size of vacuoles or air chambers used to store the oxygen. The volume of these vacuoles was very small in case of mite infested plants compared with leaves infested with weevils as the same as control. The weevils feeding reflected in increase in both, length and width of fed upon leaves.},

	abstract = {Water hyacinth (Eichhornia crassipes (Mart.) Solms-Laub.) remains a problem waterweed worldwide, for which biological control offers a sustainable solution. Under laboratory conditions, we investigated the interaction between two established weevil species Neochetina eichhorniae (Warner), Neochetina bruchi Hustache and the mirid Eccritotarsus catarinensis (Carvalho) which have been released together in several countries. Adult and immatures of E. catarinensis had high mortality on plants with high levels of old feeding scars from adult N. eichhorniae and N. bruchi and was significantly different at p 0.05. In contrast, mirid survived well on plants with recent feeding scars from Neochetina spp. or on undamaged plants. Our results indicate that the mirid is compatible with the two weevil species for improving biological control of the weed.},

	abstract = {Data on the occurrence of ten weevils species associated with Pistia stratiotes L. (Araceae), from Ilha de Marchantaria, Manaus (Amazonas, Brazil) are presented for the irst time. During the period from March to August 2005, 809 weevils specimens were sampled on P. stratiotes, distributed across nine species allocated in five genera of Stenopelmini, in addition to one unidentiied species in the Cryptorhynchinae. Among the Stenopelmini, Argentinorhynchus breyeri Brethes, 1910 (N = 665) was the dominant species, with the highest abundance in July (N = 189) and the lowest in August (N = 11), while Ochetina uniformis Pascoe, 1881 (N = 63), Neochetina bruchi Hustache, 1926 (N = 45), Neohydronomus pulchellus Hustache, 1926 (N = 15), Neohydronomus afinis Hustache, 1926 (N = 10), A. squamosus (Hustache, 1926) (N = 5), Neochetina eichhorniae Warner, 1970 (N = 4), A. minimus O{\textquoteright}Brien \& Wibmer, 1989b (N = 1), and Tanysphiroideus sp. (N = 1) had lower abundances. In addition, the co-occurrences of A. breyeri, A. minimus, and A. squamosus on P. stratiotes were recorded for Brazil and the irst records of A. minimus and A. squamosus were observed for the State of Amazonas.},
