The agroecological movement in Brazil started with critiques of the impacts of agricultural systems based on the Green Revolution. The value of yield losses caused by insects is around 1.6 billion dollars annually 5 Chemical insecticides, applied mainly to control fruit flies and moths, still represent the primary form of control in the Serra Gaúcha imunizadoras em porto alegre Region, although recent progress has been achieved by alternative pest-control technologies, such as the use of pheromones, toxic baits and mass trapping 6 , 7 , 8 Chemical control through insecticides is often ineffective and it may have an indirect effect on non-target pests, mainly due to its negative impact on natural enemy populations.
If these infringements are indeed occurring, they could be impacting pollinators through excessive use of these products as a result of incorrect dosages, times of day, methods of application and even incorrect mixtures of different products see 21. For example, the Brazilian Ministry of the Environment recently published a document on risk assessment of insecticides regarding bees containing instructions and listing bee-friendly practices 57. Therefore, even if farmers prefer to use insecticides for pest control, they can adopt attitudes that would reduce the risk of serious harm to bees 57.

Considering the damage caused by terrestrial gastropods in strawberry producing areas in southern Brazil, this study aimed to i) identify the species associated with Fragaria x ananassa in rural properties in municipalities of Parana State, Brazil; ii) describe and illustrate the diagnostic morphological and conchology features of the mollusk species; iii) construct an illustrated key based on these morphological and conchology features; iv) analyze two species collected in March 2017 to investigate the possible occurrence of parasitic nematodes of medical importance.
Species that were collected in small numbers per plant and were restricted to only 1 municipality or micro-region of São Paulo were: Ceroplastes floridensis Comstock, Parasaissetia nigra (Nietner) (Coccidae), Melanaspis smilacis (Comstock) (Diaspididae), and L. minutus (Pseudococcidae) ( Fig.

If insecticide use in Brazil could be reduced considerably, at least four major advantages of partnerships between farmers and beekeepers could be reaped: (1) greater growth of honey production, (2) increased profits for beekeepers from hive rental, (3) increased size of harvests in tonnage due to increased weight of fruit and seeds resulting from more effective pollination and (4) expansion and increased value of Brazilian agricultural products ("green card") in more demanding international markets.
Such relatively low activity against aphids may indicate that these plant species are not aphid-resistant or that aphid settling inhibition activity may be found in more lipophilic compounds such as those located on the leaf surface, which may have not been extracted in our study.
The state of Rio Grande do Sul produces 63% of all rice in Brazil 56 The association between rice paddy workers and leptospirosis has already been described in the literature 6 , 57 Working conditions in rice fields have been studied in Peru and results highlight occupational hazards linked to leptospirosis infection, such as long period of exposure to water, lack of use of any personal protection equipment, and presence of skin wounds 57 It is very important to raise awareness about the risk of this disease in critical areas and promote personal protection equipment (PPE).

Some of the main damage symptoms caused by scale insects on citrus trees observed during this study were: (1) chlorosis on the leaves, caused mainly by species of diaspidids; (2) dieback of twigs and branches on plants infested by U. citri and L. rugosa; (3) early fruit drop in fruits infested by P. cinerea, in the calyx region; (4) sooty mold f
