“…This work complements the large volume of research conducted elsewhere (28,74,82,110,111), and as shown in these studies, Chinese research shows that fecundity typically declines when DBM is reared at constant temperatures higher than 25 • C (13,61,69,72). However, data show enormous variations and the effects of host plant, adult feeding, quality of adult food, photoperiod and temperature, and interactions between these fundamental factors on DBM growth, development, and potential fecundity remain poorly understood.…”

The diamondback moth (DBM), Plutella xylostella (L.), costs the Chinese economy US$0.77 billion annually, and considerable research has focused on its biology, ecology, and management. Much of this research has been published locally and is inaccessible outside China. Since 1990 Brassica vegetable production has increased 20-fold and production practices have intensified, but losses continue to increase. Insecticide use is widespread and many DBM populations, particularly in southern provinces, are resistant to multiple compounds. The molecular bases of several insecticide resistance mechanisms are well understood, and genetic studies suggest that insecticide-resistant populations migrate northward in spring and that back migrations may occur in southern provinces. Fundamental studies have improved our understanding of the effects of temperature on DBM population dynamics and distributions and of interactions between DBM and its well-established parasitoid fauna. Nationally coordinated research is developing regional management strategies that integrate locally appropriate biological, physical, cultural, and insecticidal control, but sustaining their adoption will prove an enormous challenge.

“…(1991) indicated that females fed on C. bursa‐pastoris during the larval stage deposited significantly fewer eggs than those reared on broccoli and cabbage. Yamada and Umeya (1972) reported that P. xylostella collected from cabbage fields during winter had larger pupae and laid more eggs than those collected during summer. The long‐winged females of the carabid beetles Calathus cinctus Motschulsky and C. melanocephalus L. had higher fecundities than the short‐winged females (Aukema 1991), and longer‐winged females of the milkweed bug Oncopeltus fasciatus Dallas (Hemiptera: Lygaeidae) had a larger body size and a higher fecundity than the shorter winged females (Palmer & Dingle 1989).…”

The diamondback moth Plutella xylostella (L.) (Lepidoptera: Plutellidae) is an important pest of cultivated brassicaceous crops worldwide. The host plant preferences, developmental biology and survival and longevity of P. xylostella are relatively well understood on commercial crop species; however, its relationship with brassicaceous weeds is poorly known. Sinapis arvensis L., Erysimum cheiranthoides L. and Capsella bursa-pastoris (L.) Medicus are among the most common brassicaceous weeds worldwide and can serve as important bridge hosts of P. xylostella. In this study, preference and performance of P. xylostella were compared on these weed species. In free-choice situations, females deposited 5.5 and 18.8 times more eggs on S. arvensis than on E. cheiranthoides and C. bursa-pastoris, respectively. Survival from neonate to pupa and from pupa to adult was highest on S. arvensis and E. cheiranthoides and lowest on C. bursa-pastoris. Development was fastest, foliage consumption was greatest, pupae and silk cocoons were heaviest, adult body masses and longevities were highest and forewings were largest for both females and males when reared as larvae on S. arvensis. Realized fecundity of new generation adults was highest for individuals reared on S. arvensis compared to those reared on E. cheiranthoides or C. bursa-pastoris. Relative growth rates of pupae and adults were highest on S. arvensis, suggesting that this plant species is a high-quality host for P. xylostella compared with other species tested. Potential impacts of these wild brassicaceous species on P. xylostella populations are discussed.

“…Flight behavior of insects is influenced by adult 203 size and composition. In some species, such as the scolytid Dendroctonous pseudotsugae (Atkins, 1975), the fruit fly Drosophila melanogaster (Roff, 1977), the pentatomid Nezara viridula (Kester & Smith, 1984), the lygaeid Oncopeltus fasciatus (Holmes et al, 1979) and the yponomeutid Plutella xylostella (Yamada & Umeya, 1972), individuals with increased flight activity tend to be larger or contain a higher percentage of lipid. In others, such as the culicid Aedes taeniorhynchus (Nayar & Sauerman, 1969), Cicadulina species (Cicadellidae) (Rose, 1972), and the tortricids Choristoneura fumiferana (Sanders & Lucuik, 1975) and Epiphyas postvittana (Danthanarayana, 1976), smaller individuals tend to show increased flight activity.…”

Rearing larvae of Ips calligraphus (Germar) (Coleoptera: Scolytidae) in bolts of typical slash pine, Pinus elliottii Engelm. var. elliottii, with ‘thin’ (TN; 0.5–1.5 mm) phloem (inner bark) relative to adult beetle body width significantly reduced body weight and lipid content of emerging adults compared with ‘thick’ (TK; 2.5–3.5 mm) phloem‐reared adults. Unmated (pre‐nuptial) TK beetles averaged 2‐fold longer daily and lifetime flight duration than TN beetles. Daily flights were highly variable, averaging < 20 min (longest daily flight = 173 min). TK and TN beetles initiated flight, and the greatest number flew, on the first or second day after emergence from their rearing bolt % of beetles flying and survival gradually declined to zero by day 9. Males (both TK and TN) averaged 2.5 days of flight, ca. 1 day longer than females. Fliers lived ca. 2‐fold longer than non‐fliers. Among TK and TN fliers, significant but weak positive correlations occurred between body weight and lifetime flight duration. Poor correlation between lifetime flight duration and longevity suggests little physiological cost to flight, but effects on fecundity were not assessed. Flight by mated, egg‐laying (post‐nuptial) beetles was substantially delayed (peaking on day 6), suggesting degeneration and subsequent regeneration of flight muscles. Résumé Comportement de vol d'Ips calligraphus élevé sur Pinus elliottii au phloem plus ou moins épais; relations avec l'âge, le poids et la teneur en lipides Le comportement de vol d'Ips calligraphus GERMAR (Scolytidae) a été examiné au laboratoire par une technique de vol captif. La génération parentale avait été artificiellement introduite, suivant la taille des adultes (1,6 à 2,1 mm) dans des morceaux de Pinus elliottii Engelm. variété elliottii au phloeme épais (TK = 2,5 à 3,5 mm) ou fin (TN = 0,5 à 1,5 mm) les larves se sont développées dans ces morceaux de pin. Le poids et la teneur en lipide des adultes obtenus à partir de TN étaient sig‐nificativement inférieure à ceux de TK. Le poids des mâles les plus gros a été plus réduit que celui des femelles; les mâles les plus petits semblaient être moins efficaces dans l'initiation des attaques sur les arbres, et les femelles les plus petites ont eu une fécondité réduite. Les durées de vol quotidiennes pendant la vie des mâles TK vierges étaient en moyenne deux fois plus longues que celles des mâles TN. Les durées de vol quotidiennes étaient très variables: en moyenne moins de 20 minutes, mais la plus longue a été de 173 mn. En moyennes les adultes TN et TK ont commencé à voler, et volaient en plus grand nombre, le premier et le second jour après l'émergence. Ensuite la fréquence d'adultes volants et le pourcentage de surviveants, ont graduellement diminué jusqu'à tomber à zéro le neuvième jour. Les mâles TN et TK avaient des vols quotidiens plus longs et volaient environ 1 jour de plus que les femelles. L'activité de vol accrue des mâles reflète leur besoin de trouver dans la nature des arbres convenables; les vols des femelles peuvent généra...
