Food consumption of Chilocorus kuwamae Silvestri (Coccinellidae)

Temperature-dependent development of Chilocorus bipustulatus (Coleoptera: Coccinellidae).

The effect of temperature on development and survival of Chilocorus bipustulatus L. (Coleoptera: Coccinellidae), a predator of many scale insects, was studied under laboratory conditions. The duration of development of egg, first, second, third, and fourth larval instars, pupa, and preovioposition period at seven constant temperatures (15, 17.5, 20, 25, 30, 32.5, and 35°C) was measured. Develo...

Factors affecting utility of Chilocorus nigritus (F.) (Coleoptera: Coccinellidae) as a biocontrol agent

Chilocorus nigritus (F.) has been one of the most successful coccidophagous coccinellids in the history of classical biological control. It is an effective predator of many species of Diaspididae, some Coccidae and some Asterolecaniidae, with an ability to colonize a relatively wide range of tropical and sub-tropical environments. It appears to have few natural enemies, a rapid numerical respon...

Van Driesche et al.: Euonymus Scale Natural Enemies 1 RELEASE, ESTABLISHMENT AND SPREAD OF ASIAN NATURAL ENEMIES OF EUONYMUS SCALE (HOMOPTERA: DIASPIDIDAE) IN NEW ENGLAND

Between 1990 and 1995, the USDA/APHIS National Biological Control Laboratory in Niles, MI, Texas A&M University, and the University of Massachusetts conducted a biological control introduction program against the Asian diaspidid scale insect Unaspis euonymi (Comstock), a pest of woody landscape plants. Two species of predators ( Chilocorus kuwanae Silvestri, Coleop.: Coccinellidae and Cybocepha...

The Impact of Food Stamp Program on Relative Food Consumption and Food Choices

  I n this paper, the effects of the Food Stamp (FS) Program (now referred to as Supplemental Nutrition Assistance Program-SNAP) on individuals’ food choices are evaluated. In other words, I examine how households' food choice or relative food consumption is changed by FS participation. For this purpose six food groups are created using 2016 Consumer Expenditure Diary Surv...
