Malathion has been released to the environment mainly as a result of its use as an insecticide on food and feed crops, noncrop agricultural use, home and garden use, and public health use (for medfly and mosquito control). (cdc.gov)

Understanding the biology and behavior of weevils is essential for effective pest management in various agricultural and industrial settings. (michepestcontrol.com)
In order to take advantage of this behavior, collect the adult curculios with a wide mouth container half full of soapy water. (tripod.com)

The primary aim of this study was to assess the individual impact of the gorse seed weevil (Exapion ulicis), gorse spider mite (Tetranychus lintearius) and gorse thrips (Sericothrips staphylinus) on the growth and development of gorse. (edu.au)
A bioassay was conducted to determine the toxicity of herbicides and adjuvants commonly used to control gorse on adult and juvenile gorse thrips. (edu.au)
The herbicide triclopyr/picloram was found to be consistently the most toxic chemical to both juvenile and adult gorse thrips. (edu.au)
Metsulfuron methyl was not significantly toxic to either adult or juvenile gorse thrips. (edu.au)
Both adjuvants seemed to increase the toxicity of all the herbicides on both juvenile and adult gorse thrips The integration of chemical and biological control using the gorse thrips is discussed. (edu.au)

This weevil presents an enormous threat to the ornamental and edible date palm industries in California. (ucr.edu)
In December 2010, this weevil was discovered infesting ornamental Canary Islands date palms (CIDP) (Phoenix canariensis) in Tijuana. (ucr.edu)

Understanding their life cycle, relationships with other organisms, and methods of control can lead to a more nuanced appreciation of these tiny giants in the insect world. (plantpropagation.org)

In many cases the weevil has cleared salvina infestations by 90% or more in under one year. (wikipedia.org)
Recent research has been conducted using electronic listening devices or dogs trained to recognize the scent of weevils or palm decay to detect infestations at low densities earlier in the process. (ict4water.eu)

Once they became established, weevil numbers and damage decreased dramatically. (fieldcropnews.com)
Weevil damage increases the longer the crop remains not harvested. (infonet-biovision.org)
Rose weevils damage to roses in several different ways. (tripod.com)
First the weevils damage roses by making feeding punctures with their long beaks on rose buds, calyx, and peduncle. (tripod.com)
The greatest damage to roses is cause when adults feed on flower buds. (tripod.com)
Rose weevils start to damage roses at the first sight of bud formation and they tend to prefer certain roses more than others. (tripod.com)
Keeping notes on varietal preference is important for successful scouting the and control of the weevils early before they cause widespread damage on the roses. (tripod.com)

The Municipal District of Bonnyvllle is killing off the noxious weed, Canada Thistle, one weevil at a time. (bonnyville.ab.ca)

Many weevils have wings, but they are often hidden beneath the hardened elytra. (michepestcontrol.com)
When weevils are at rest, their wings are tucked under the elytra. (michepestcontrol.com)

You can also discover more about work on M. borraginis for houndstongue and other biological controls for other weeds in the Weed Biological Control Progress Report 2020 from CABI in Switzerland here . (cabi.org)
In many states, counties, and cities, control of noxious weeds is mandated by law. (pesticide.org)
1 Many states designate weeds as noxious, and both state and local governments commonly have laws that require landowners to control noxious weeds that grow on their property (7 U.S.C. 61 § 2802). (pesticide.org)
That means these weeds must be controlled, which is difficult to do. (bonnyville.ab.ca)
The bio-control releases are a component of the Lapwai Creek restoration plan's objective of reducing noxious weeds within the watershed. (nezperceswcd.org)
The release of L. minutus is part of a program to introduce a complex of spotted and diffuse knapweed enemies to help control these weeds. (cornell.edu)

Even people who work on pollination don't usually consider weevils as one of the main pollinators, and people who work on weevils don't usually consider pollination as something relevant to the group," says de Medeiros. (earth.com)
Oil palm, which is used to make peanut butter and Nutella, was not a viable industry until someone figured out that the weevils found with them were their pollinators," says De Medeiros. (earth.com)
He argues that the preconception of weevils as non-pollinators held back the industry from realizing this potential for much longer than necessary. (earth.com)
In summary, while weevils might be small, their ecological impact as pollinators is anything but. (earth.com)
Adult Green Lacewings are minor pollinators and do not provide active pest control themselves. (arbico-organics.com)

In cooperation with the Nez Perce Tribe's BioControl Center, District staff assisted with a county wide survey to determine the extent of the bio-control agent distribution. (nezperceswcd.org)

The eggs hatch inside the pest where the young wasp feed and develop, eventually killing the weevil. (fieldcropnews.com)

In my garden near Sacramento, California the weevils usually show up from early April thorough early May. (tripod.com)

The results show that D. suzukii has adapted to exploit a succession of irrigated crops and feral habitats in mixed landscapes of a semi-arid region with cold winters and hot dry summers, and are shaping strategies for pest management and for biological control. (bioone.org)

To facilitate field-based identification of this predator, we present descriptions of eggs, nymphal stages, and adults. (bioone.org)

Adult pepper weevils feast on leaves and blossoms, and both adults and larvae bore into young fruit pods in order to feed on their seeds [Figure 2] Typically, infested fruit pods become discoloured and abort after withering at the stem and/or calyx [Figure 3]. (greenhousecanada.com)

Rose weevil adults on rose buds. (tripod.com)
Weevils use the buds for feeding and laying their eggs. (tripod.com)
The adults drill small round holes deep into the flower buds and hips for feeding and egg-laying. (tripod.com)
The adult punctures the floral parts contained inside buds. (tripod.com)
If flower buds are not plentiful, the adult curculio may feed on the tips of new rose shoots, causing the death of terminals. (tripod.com)
Since the adult made holes in the buds, the peduncle (stem right below the hip) becomes weak and eventually the buds fall off. (tripod.com)
In the absence of buds on preferred varieties, the weevils will feed on growing tips. (tripod.com)

In the meantime, we are maintaining colonies of the weevil at CABI and in quarantine in the USA, so that we will be ready to release it when all the necessary checks and approvals have been done and granted. (cabi.org)
In the lab, colonies of adult weevils can be maintained for 2-3 months on a mixed diet of cut apples and bananas (with the skin left on), and split sugar cane. (ucr.edu)

The recommendation by the United States Department of Agriculture (USDA) Technical Advisory Group (TAG) signals a key accomplishment in the process of getting M. borraginis released in the field as a classical biological control agent against houndstongue ( Cynoglossum officinale ) - a rangeland weed in the western USA and adjacent Canadian provinces. (cabi.org)
It works very effectively in combination with Beauveria bassiana, Pseudomonas fluorescens, Trichoderma Viride, the bio control agent. (biosar.in)
