“…1,3–5 This obnoxious pest ( B. zonata ) occurring in different ecological regions of Pakistan often causes up to 100% losses in different fruits. 6,7 European Plant Protection Organization categories B. zonata as an A1 key quarantine pest 8 by several countries 9 and being polyphagous, 10 tephritidae flies attack on several fruit and vegetable species such as mango ( Mangifera indica ), guava ( Psidium guajava ), peach ( Prunus persica ), fig ( Ficus carica ), apple ( Malus domestica ), apricot ( Prunus armeniaca) and tomato ( Solanum lycopersicum ), pepper ( Piper nigrum ) and eggplants ( Solanum melongena ) as secondary hosts. 11 In addition, the environmental conditions (temperature, rainfall and relative humidity (RH)) are also known to influence the extent of infestation which may vary between 30% and 100%.…”

The indiscriminate application of synthetic pesticides on horticultural plants for the management of Bactrocera zonata has both economic and environmental implications due to the biomagnification of harmful residues in humans via the food chain. This necessitates the use of some eco-friendly control measures such as insect growth regulators (IGRs) as an alternative. A laboratory experiment was laid out to determine the potential chemosterilant effect of five IGRs including pyriproxyfen, novaluron, lufenuron, buprofezin, and flubendiamide at six different concentrations on B. zonata after treating adult diet. Using the oral bioassay, B. zonata were fed on IGRs impregnated diet (50–300 ppm/5 mL diet) which was replaced with the normal diet after 24 h of feeding. Ten pairs of B. zonata were placed in a separate plastic cage accommodating an ovipositor attractant guava for eggs collection and calculation. An analysis of the result revealed that fecundity and hatchability were higher at a low dose and vice versa. Lufenuron at 300 ppm/5 mL of diet significantly decreased the fecundity rate (31.1%) as compared to pyriproxyfen, novaluron, buprofezin and flubendiamide, which had 39.3%, 39.3%, 43.8%, and 47.5%, respectively. The lowest hatchability (19.9%) was noted in lufenuron treated diet followed by pyriproxyfen, novaluron, buprofezin, and flubendiamide, which had 22.1%, 25.0%, 30.9%, and 31.6%, respectively. Furthermore, in a population of crosses between the lufenuron treated male and female, a significant decrease in fecundity (45.5%) and hatchability (51.7%) was noted as compared to other IGRs. Overall, this study identified the chemosterilant potential of lufenuron on the population of B. zonata which can be integrated for its management strategy.
