Insecticide resistance survey is an in-situ biomonitoring method to assess potential impact of pesticides that exhibit direct economic consequences when leading to control failure of insect pest species. Nonetheless, the latter phenomenon is frequently neglected. Their spatial dependence and mapping are also seldom considered and when complexes of related pest species are involved, such as the rice stink bugs from the Neotropics, Oebalus poecilus, and O. ypsilongriseus, the scenario is even worst. Insecticide use is common against both species, particularly with the neonicotinoid thiamethoxam, and despite suspicion of a shift in O. poecilus historical dominance and complaints of control failure, the role of this insecticide in this context was never tested. Thus, we screened populations from both species for thiamethoxam resistance within rice fields from central Brazil. The levels of thiamethoxam resistance and control failure likelihood were recorded and their spatial dependence was tested and geographically mapped. The thiamethoxam potency was similar between species, which also exhibited overlapping levels of resistance. Thus, this insecticide does not seem involved in eventual shifts in species dominance and the occurrence of O. ypsilongriseus is frequent. Thiamethoxam resistance was detected in both species, nearly half of the populations of O. poecilus and about a third of O. ypsilongriseus, but at low levels (MenosInsecticide resistance survey is an in-situ biomonitoring method to assess potential impact of pesticides that exhibit direct economic consequences when leading to control failure of insect pest species.

Thiamethoxam resistance was detected in both species, nearly half of the populations of O. poecilus and about a third of O. ypsilongriseus, but at low levels (<ten-fold). As a consequence, the risk of control failure with thiamethoxam was also low. Spatial dependence was significant for both species and phenomena (i.e., thiamethoxam resistance and control failure), prevailing in about the same area and likely reflecting the local pattern of insecticide use. 650 $aInsecticide resistance 650 $aInsects 650 $aNeonicotinoid insecticides 650 $aOebalus poecilus 650 $aOebalus ypsilongriseus 650 $aPest management 650 $aRice 650 $aArroz 650 $aInseticida 650 $aOryza Sativa 650 $aPraga de Planta 650 $aResistência Química 653 $aNeotropical rice 653 $aSpatial survey 700 1 $aCAMPOS, S.

This study investigated the effects of irrigation using treated sewage effluent (TSE) combined with nitrogen (N) fertilization on the productivity and quality of bermudagrass, and on its economic feasibility under tropical conditions. The treatments employed were SI – no irrigation and no fertilization; A100 (control) – irrigation with potable water plus 520 kg N ha−1 year−1 provided as NH4NO3; E0, E33, E66, and E100: irrigation with treated sewage effluent plus 0, 172, 343 and 520 kg N ha−1 year−1 as NH4NO3, respectively. Chemical properties of TSE, shoot dry matter production, N concentration in bermudagrass were determined, and benefit–cost and economic viability analyses were carried out. Tree years of irrigation with TSE had agronomical benefits to bermudagrass such as: (i) saving 33% in N fertilizer by adding of 275 kg N ha−1 year−1, increasing N accumulation in the soil; (ii) providing 70% of the N as NH4 +, which is the form most quickly assimilated by the plants; (iii) building up dry matter production with 7 Mg ha−1 year−1 and (iv) increasing leaf N concentration in leaf tissue. The main benefit of TSE irrigation occurs in drought seasons with the increase in N concentration in bermudagrass shoots. Higher N concentration in leaf tissue elevates the quality and the sales price for the grass harvested, thus optimizing the benefit–cost ratio for the producer. Therefore, TSE irrigation is a viable cost-effective alternative if the N concentration in the leaf tissue is considered in the sales price.
