INTRODUCTION Four mealybug species cause economic damage in California vineyards. These are the grape mealy- bug, Pseudococcus maritimus (Ehrhorn); obscure mealybug, Pseudococcus viburni (Signoret); longtailed mealybug, Pseudococcus longispinus (Targioni-Tozzeti); and vine mealybug, Planococcus ficus (Signoret) (Godfrey et al., 2002). The grape, obscure, and longtailed mealybugs belong to the Pseudococcus maritimus-malacearum complex–a taxonomically close group of mealybugs (Wilkey and McKenzie, 1961). However, while the origins of the grape and longtailed mealybugs are believed to be in North America, the ancestral lines of the obscure mealybug are unclear. Regardless, these three species have been known as pests in North America for nearly 100 years. The vine mealybug, in contrast, was first identified in California in the Coachella Valley in the early 1990s (Gill, 1994). It has since spread into California’s San Joaquin Valley and central coast regions, with new infestations reported each year. The four species are similar in appearance; however, mealybugs in the P. maritimus- malacearum complex have longer caudal filaments than vine mealybug (Godfrey et al., 2002). -

Conotrachelus Nenuphar

HOSTS Conotrachelus nenuphar, a native weevil of North America, was originally a pest of native rosaceous plants. However, the introduction of exotic rosaceous plants into North America, notably cultivated plants such as apple ( Malus domestica) and peach (Prunus persica) trees, widened the host range of C. nenuphar and demonstrated its adaptability to new hosts (Maier, 1990). The distribution of C. nenuphar broadly conforms to the distribution of its native wild hosts Prunus nigra, Prunus americana and Prunus mexicana (Smith and Flessel, 1968). Other wild hosts include Amelanchier arborea, A. canadensis, Crataegus spp., Malus spp., Prunus alleghaniensis, P. americana, P. maritima, P. pensylvanica, P. pumila, P. salicina, P. serotina, P. virginiana and Sorbus aucuparia (Maier, 1990). Important cultivated hosts are apples, pears (Pyrus), peaches, plums and cherries (Prunus) and blueberries (Vaccinium corymbosum). In addition to its rosaceous main hosts, C. nenuphar can also be found on blackcurrants (Ribes spp. - Grossulariaceae) and blueberries (Vaccinium spp. - Ericaceae) (Maier, 1990). Second generation C. nenuphar adults appear to attack a narrower range of some cultivated species than the first generation (Lampasona et al., 2020). Prunus, Pyrus and Malus spp. are widely cultivated throughout the Euro-Mediterranean region. In addition, if the pest was introduced to this region, the adaptability of the species to new hosts would probably result in an extended host range. -
Birch Defoliator Yukon Forest Health — Forest Insect and Disease 4
Birch Defoliator Yukon Forest Health — Forest insect and disease 4 Energy, Mines and Resources Forest Management Branch Introduction The birch leafminer (Fenusa pusilla), amber-marked birch leafminer (Profenusa thomsoni), birch leaf skeletonizer (Bucculatrix canadensisella) and the birch-aspen leafroller (Epinotia solandriana) are defoliators of white birch (Betula papyrifera) in North America. Of the four, only the Bucculatrix is native to North America, but it is not currently found in Yukon. The other three species, as invasives, pose a far greater threat to native trees because their natural enemies in the form of predators, parasites and diseases are absent here. The birch leafminer was accidently introduced from Europe in 1923 and is now widely distributed in Canada, Alaska and the northern United States, though it has not yet been found in Yukon. The amber-marked birch leafminer was first described in Quebec in 1959 but is now found throughout Canada, the northern contiguous U.S., and Alaska. The amber-marked birch leafminer has proven to be, by far, the more damaging of the two species. Both species are of the blotch mining type as opposed to the skeletonizing Bucculatrix and the leafrolling Epinotia. Amber-marked leafminer damage is typically found along road systems. Infestations along roadsides are often greater in areas of high traffic, or where parked cars are common, suggesting that this pest will hitchhike on vehicles. It was first identified in Anchorage, Alaska in 1996 and has since spread widely to other communities. In areas of Alaska, efforts to control the spread of the amber-marked birch leafminer have been underway since 2003 with the release of parasitic wasps (Lathrolestes spp.). -

This study evaluated the effects of nitrogen fertilization (0, 75, 150 and 300 ppm N) on the growth, % nitrogen, % carbon, lipid, and protein contents of basil plants (Ocimum basilicum L., Lamiaceae), and the subsequent impacts of host-plant nutritional status on the life history and total lipid and protein contents of the Madeira mealybug. -

Parasitoid females are known to rely on these important sensory receptors in their antennae to locate and select the host [1-3]. Anagyrus sp. near pseudococci (4) is a solitary endoparasitoid of pest mealybugs (Hemiptera, Pseudococcidae), such as Planococcus ficus (Signoret) and P. citri (Risso) [5]. The females of A. sp. near pseudococci were recently shown to respond to the sex pheromone of P. ficus and use this kairomonal cue in host location [5, 6]. However, little is still known about the antennal receptors that might be involved in the parasitoid host selection behavior. In this study, using SEM (JEOL JSM 5200 LV), we describe the morphology and distribution of sensilla on the antenna of 18 females and 2 males of A. sp. near pseudococci. Eight types of antennal sensilla were found on adult wasps. -
