“…Diamondback moth is a specialist herbivore feeding only on members of the family Cruciferae (Talekar & Shelton 1993). However, Gupta & Thorsteinson (1960a,b) found that under laboratory caged conditions DBM females laid eggs on plants of pea, sweet clover, coumino clover and tomato; larvae showed feeding and survival to various extents on these plants but could complete its life cycle only on pea, Pisum sativum . Recently, Löhr & Rossbach (2004) found a field DBM population on pea crops in Kenya, and demonstrated that this DBM population could survive well on both pea and kale.…”

Experience‐induced preference for oviposition repellents derived from a non‐host plant by a specialist herbivore

Foraging adults of phytophagous insects are attracted by host-plant volatiles and supposedly repelled by volatiles from non-host plants. In behavioural control of pest insects, chemicals derived from non-host plants applied to crops are expected to repel searching adults and thereby reduce egg laying. How experience by searching adults of non-host volatiles affects their subsequent searching and oviposition behaviour has been rarely tested. In laboratory experiments, we examined the effect of experience of a nonhost-plant extract on the oviposition behaviour of the diamondback moth (DBM), Plutella xylostella, a specialist herbivore of cruciferous plants. Naive ovipositing DBM females were repelled by an extract of dried leaves of Chrysanthemum morifolium, a nonhost plant of DBM, but experienced females were not repelled. Instead they were attracted by host plants treated with the non-host-plant extract and laid a higher proportion of eggs on treated than on untreated host plants. Such behavioural changes induced by experience could lead to host-plant range expansion in phytophagous insects and play an important role in determining outcome for pest management of some behavioural manipulation methods.

“…Glucosinolates act as key stimulants for oviposition to adults (Gupta and Thorsteinson, 1960b;Reed et al, 1989), and as feeding stimulants to larvae (Thorsteinson, 1953). In addition, allyl isothiocyanate stimulates egg production in adults (Hillyer and Thorsteinson, 1969) and inhibits dispersal of larvae from host plants (Gupta and Thorsteinson, 1960a).…”

Larvae of the diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), a crucifer specialist, refuse to feed on the wintercress, Barbarea vulgaris R. Br. (Brassicaceae). The mechanism of this unacceptability to P. xylostella was evaluated by a series of no-choice bioassays using leaf disks. Topical application of sinigrin enhanced feeding of the larvae on the leaf disks of a non-host plant, lettuce (Lactuca sativa L.), but not on those of B. vulgaris. Application of the crude methanolic extract from B. vulgaris leaves deterred P. xylostella feeding on the leaf disks of cabbage (Brassica oleracea L.) in a dose-dependent manner. This feeding deterrent activity was transferred predominantly to the chloroform fraction, but not to the n-hexane or water fractions. These results suggest that the unacceptability of B. vulgaris to P. xylostella larvae is mainly due to chemical constituent(s) extractable with chloroform.

“…Diamondback moth has been recorded in the field from host plants outside its 'natural' (=crucifers) host plant range before. Unfortunately, no data were taken on survival and growth of DBM but the authors "did not observe any differences between the survivors on peas and the ones raised on mustard" (Gupta and Thorsteinson, 1960a). To date, only few studies have looked into the host plant range of DBM, all under laboratory conditions.…”

“…Because of the continuous increase in percentage mining through all generations of selection on pea and the almost parallel increase of survival, it appeared mining was the key to adaptation. The importance of a feeding stimulus for neonate DBM larvae was also stressed by Gupta and Thorsteinson (1960a), who found that larval survival on (non-host) leguminous plants is greatly enhanced when neonate larvae are allowed to feed first on mustard for 10-12 hours. The data showed as well that there was a significant interaction between mining and generation of selection.…”

A strain of diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), adapted to peas was detected in 1999 in the export vegetable growing area south of Lake Naivasha in the Rift Valley Province of Kenya. The pea strain (DBM-P) was compared in laboratory studies to the normal crucifer strain (DBM-C). Whereas DBM-P performed comparably well on kales and peas, the cabbage strain (DBM-C) suffered heavy mortality on peas. Out of the 250 DBM-C first instars, only six reached adult stage on pea. In addition, larval development was prolonged by five days on peas as compared to kale, and larval growth was greatly reduced. Pupal weights of DBM-C survivors on pea were significantly lower (3.8 mg) than of DBM-P (4.6 mg) and those of both strains on kale (5.7 and 5.3 mg, respectively). Neonate larvae of the pea strain mined on both kale and pea but both the proportion of larvae mining and the number of mining days were lower than for DBM-C on kale. The latter failed completely to mine on pea.A laboratory culture was started with the DBM-C survivors on pea and the performance of the progeny compared on kale and pea in three additional generations of selection. Larval survival increased from 2.4% in the first generation to 28.6%, 41.3% and 49.7% in the second, third and fourth generation, respectively. Pupal weight of larvae reared on pea increased with each generation of selection, but it remained significantly lower than of larvae reared on kale. In spite of the large differences in larval mining on the two host plants, performance on peas was not related to the ability of DBM-C to mine on pea but rather to the ability to initiate feeding without the normal stimuli present in crucifers. Pupal mortality for larvae from both hosts was similar when larvae of equal weight were compared, suggesting acceptable suitability of pea for larval development once the new host is accepted. The implications of these findings on adaptability of DBM to plants beyond its normal host range are discussed.Key Words: Plutella xylostella, host range, new host record, selection for adaptation to non-hosts Resume-Une souche de la fausse-teigne des cruciferes, Plutella xylostella (L.)
