Attract-and-kill as a new strategy for the management of the potato tuber mothsPhthorimaea operculella(Zeller) andSymmetrischema tangolias(Gyen) in potato: evaluation of its efficacy under potato field and storage conditions

Abstract

Attract-and-kill is very effective in controlling the two potato tuber moth species under both field and storage conditions; it is a new, attractive and (for storage conditions) low-cost method that can be easily integrated in potato pest management programmes, especially in small-scale agricultural systems of the tropics and subtropics.

Successful management of Halyomorpha halys (Hemiptera: Pentatomidae) in commercial apple orchards with an attract‐and‐kill strategy

“…Moreover, formulation changes may result in season‐long lure attractiveness (Leskey and Short, unpublished), thus eliminating the need to replace lures and reducing the number of lures required annually. While the distance of attraction to these semiochemicals is currently unknown, AK may also act in areawide suppression of H. halys , locally depleting individuals on a farm, which may increase the economic viability of this approach. For example, a 40 km 2 comprehensive areawide pest management program with at least one AK trap per km yielded 91% and 61% reductions in fruit infestation in Hawaii by Ceratitis capitata and Bactrocera dorsalis (Hendel), respectively .…”

Tools for detecting insect semiochemicals: a review

“…In this case, pheromones are used in traps to attract a large number of insects and thus reduce the insect population to economically acceptable levels [16].…”

Occurrence of Parthenogenesis in Potato Tuber Moth

“…Potato tuber moth, Phthorimaea operculella (Zeller; Lepidoptera: Gelechiidae) is one of the major pests of solanaceous crops worldwide including potato ( Solanum tuberosum L.), tobacco ( Nicotiana tabacum L.), tomato ( Solanum lycopersicum L.), and eggplant ( Solanum melongena L.) ( Rondon 2010 , Kroschel and Zegarra 2013 , Andreadis et al 2017 ). Female moths prefer to deposit eggs on foliage, or directly on the eye buds and scars of the potato tubers in the field and the storage warehouse.…”

“…More effective and environmentally-friendly control tactics are needed. Pheromone traps have been used for population monitoring, mating disruption, and attract-and-kill of male moths ( Hindenlang et al 1975 , Persoons et al 1976 , Kroschel and Zegarra 2010 , Kroschel and Zegarra 2013 ). However, such practices can only be successful for insect species with sexual reproduction of which parthenogenesis development from unfertilized eggs does not occur.…”

“…The biology of P. operculella has been well documented ( Fenemore 1977 , Foot 1979 , Dogramaci et al 2010 , Rondon 2010 , Kroschel and Zegarra 2013 ), but parthenogenesis in this species has sparsely been mentioned. Early reports noted that parthenogenetic reproduction did occur in laboratory population of P. operculella but very rarely ( Poos and Peters 1927 , Hofmaster 1949 ).…”
