“…Cotton is a major crop in Pakistan and about 62% of all country pesticides are used for its pest management (Khan et al 2010). In cotton growing areas of Pakistan, 8-10 applications per season of several chemistries such as organophosphates (OPs), pyrethroids, neonicotinoids, insect growth regulators (IGRs), and avermectins, are conducted for the control of different cotton pests (Saeed et al 2018;Banazeer et al 2020). The over-use of pesticides to protect the economically important crops of developing countries such as cotton in Pakistan, frequently results in resistance development.…”

Dusky cotton bug Oxycarenus hyalinipennis (Costa) (Hemiptera: Lygaeidae) has been found to infesting cotton and other plants in Pakistan and some other countries. However, in Pakistan the increasing infestation of O. hyalinipennis was controlled with different insecticides, but some degree of resistance has been reported. Inheritance and cross-resistance of dimethoate resistance selection have not been documented in O. hyalinipennis previously. Therefore, this study for the first time characterized dimethoate resistance in O. hyalinipennis by inducing it in the laboratory for six generations. The selected population was 9.70-and 157-fold resistant compared with the field and laboratory population, respectively. The dimethoate resistance selection did not bring about any cross-resistance with lambda-cyhalothrin (1.47-fold) but had a very low cross-resistance with chlorfenapyr (3.03-fold) and acephate (2.21-fold) compared with the field population. The overlapping in 95% confidence limits of LC 50 ratios of F 1 (R♀ × S♂) and F 1`( R♂ × S♀) indicated the lack of maternal effects, whereas their degree of dominance of 0.54 and 0.51 suggested an incompletely dominant resistance inheritance. Multiple factors were involved in dimethoate resistance as implied from Chi-square analyses of backcrosses. In conclusion, O. hyalinipennis develops easily resistance to dimethoate due to selection. Lack of/or very low crossresistance with lambda-cyhalothrin, chlorfenapyr and acephate implies that these insecticides can be used in rotation. Moreover, dimethoate resistance inheritance was incompletely dominant, autosomal and polygenic which implies that resistance to dimethoate can be delayed by using it in rotations, alterations, mosaics and combinations.

“…41 The current results of this study indicate that the O. hyalinipennis has the ability to develop resistance to many insecticides. 7,22,60 Therefore, the Field-Pop of O. hyalinipennis was selected with sulfoxaflor under the continuous laboratory conditions for 18 generations and showed 3064.92-fold and 107.69-fold resistance in a selected strain compared to the UNSel-Pop and Field-Pop, respectively. The study of reciprocal crosses also indicated that incomplete degree of dominance.…”

BACKGROUND: Oxycarenus hyalinipennis (Costa) (Hemiptera: Lygaeidae) is a polyphagous insect pest. In Pakistan, O. hyalinipennis is managed by using different insecticides, a major concern for cotton producers, and has developed resistance to many of these. Sulfoxaflor belongs to a newly released sulfoximine family that has high efficacy for controlling sap-feeding insect pests.RESULTS: A sulfoxaflor selected-population (Sulfo-Sel-Pop) of O. hyalinipennis showed a 3064.92-fold level of resistance after continuous selection for 18 generations with sulfoxaflor compared to unselected population (UNSel-Pop). The Sulfo-Sel-Pop showed a reduction in resistance (from 3064.92 to 635-fold) without exposure for five generations, indicating unstable resistance to sulfoxaflor. Cross-resistance studies of the Sulfo-Sel-Pop revealed no or very low cross-resistance to triazophos (0.42 to 0.30-fold), deltamethrin (0.85 to 0.18-fold) and acetamiprid (1.16 to 4.86-fold) from G 4 to G 19 compared to the field population (Field-Pop). The mean value of realized heritability was 0.15 in the Sulfo-Sel-Pop (G 19 ). Significantly reduced relative fitness was determined in the Sulfo-Sel-Pop (Rf = 0.21) followed by Crossand Cross 2 [(Sulfo-Sel-Pop ♀ × UNSel-Pop ♂) (Rf = 0.70)] compared with the UNSel-Pop. The values of intrinsic rate of natural increase (r m ), biotic potential (Bp) fecundity, egg hatching, and net reproductive rate (R0) were also significantly less in the Sulfo-Sel-Pop compared to UNSel-Pop. CONCLUSION: A very high fitness cost, unstable resistance and no or very low cross-resistance in the Sulfo-Sel-Pop have great implications in designing effective strategies for managing insecticide resistance to O. hyalinipennis.

BACKGROUND: Dusky cotton bug, Oxycarenus hyalinipennis Costa (Hemiptera: Lygaeidae) is an important pest of cotton and causing economic losses to this crop. It also remains active round the year, infesting a number of host plants. Spirotetramat is a systemic insecticide and is effective against many sucking insect pests. A field collected population of O. hyalinipennis was reared in the laboratory under continuous spirotetramat selection pressure for 21 generations for the development of resistance to spirotetramat. The Spiro-Sel population was further reared for seven generations without insecticide exposure to assess the stability of spirotetramat resistance. Leaf dip method was used for the bioassays and selection. In this study, the impact of spirotetramat resistance on its stability and life history traits of Spiro-Sel, C 1 (15 Spiro-Sel♀ × 15 UNSEL ♂) and C 2 (15 Spiro-Sel♂ × 15 UNSEL ♀) O. hyalinipennis was assessed.RESULTS: Spiro-Sel (G 21 ) population developed 2333-fold and 20.83-fold resistance compared with the susceptible and unselected (UNSEL) populations, respectively. Resistance to spirotetramat was unstable after seven generations (G 28 ) when reared without exposure to any insecticide. A significant reduction in overall nymphal survival, fecundity, egg hatching and net reproductive rate of Spiro-Sel population was observed when compared with UNSEL population. Intrinsic rate of natural increase, biotic potential and mean relative growth rate were also lower in Spiro-Sel population compared to UNSEL population. The Spiro-Sel, C 1 and C 2 population had a relative fitness of 0.44, 0.51 and 0.44, respectively. CONCLUSION: Results of our study suggested that fitness cost is involved in the development of spirotetramat resistance. Unstable resistance and high fitness cost may provide great benefits to limit the evolution of resistance to spirotetramat in O. hyalinipennis.
